Hawaii 3

WOW! Look at that lizard!

I could spend all day watching and photographing these geckos. So I did. These geckos are so pretty! I would totally buy car insurance from one if it asked me. Originally from Madagascar and released by a University of Hawaii student years back with the purpose of filling my heart with joy and saving me a trip all the way to Madagascar, this is the gold dust day gecko.

Phelsuma laticauda which is Latin for "I should get a new hobby."

I could easily post one hundred more pictures and rant about how gorgeous these geckos are, but I'll spare you from boredom and post this equally self-indulging video instead. 

But there is still some boring science to be learned! Geckos, and lizards in general, tend to be visually oriented animals. Our star knocks down a piece of debris at the :12 second mark with its tail and immediately changes its gaze towards the falling object. Unfooled, the insurance spokesperson goes onto to examine the camera, spending most of the video staring directly at it. There is also a tongue flick at :43 seconds probably picking up my greasy fingerprints on the casing of my GoPro. So unfortunately, I didn't capture a lizard behaving completely "naturally" in its "natural environment," but it does show you that lizards aren't (completely) dimwitted cold-blooded lugs. They're creatures that are keenly aware of their environment and smart enough to realize when someone is trying to record them with a camera.

Hawaii 2

Frogs

You might think Hawaii is a horrible place to live if sea turtles are the only reptile readily available, but thanks to the meddling of the human race, the islands are overrun by a handful of species of lizards and frogs. Perhaps the most exciting amphibian to see is the aptly named green and black poison dart frog.

It really is green and black!

It's so exciting that you should forget about the other less exciting slimy jumpy things. But it's true, the only other frogs on Oahu include the cane toad, which is the quintessential boring toad and the American bullfrog, arguably the standard frog. There is also the Japanese wrinkled frog, but it's not terribly exciting (unless you're a weirdo who likes to find reptiles and amphibians...) and I failed at getting a nice picture of one. If only there were some fast and easy way to search for images on the internet. Oh well. Here's another fun and exciting poison dart frog.

Green and black poison dart frog? More like "fun and exciting poison dart frog."

These were intentionally released in an attempt to control the mosquito population in the wetter areas of the island, but they shirked this responsibility and are now one of the most popular attractions for visitors to this great state, further solidifying its status as a vacation hotspot. Even though we're taught the evils of moving animals around the globe, what a cool species to introduce. Someone should give that guy a Nobel Peace Prize. 

Hawaii harbors tourists of all types, human and herpetological. 

Hawaii 1

See turtles here. 

Hawaii. What negative things are there to say about Hawaii? Nothing. Hawaii was paradise. Between the beach, Spam, and streets overrun by Japanese tourists, what more could you want? Oh yeah. Reptiles. So without further ado, here is Hawaii's own green sea turtle: the Hawaiian green sea turtle.

And what's better than just one measly sea turtle? Two measly sea turtles.

"What did one sea turtle say to the other?

We're BOTH sea turtles."

And what could be better than two sea turtles? Three sea turtles, of course. But I don't have a picture with three sea turtles even though there were five of them lying on the beach together. Instead, here's this exciting shot of a sea turtle getting hit by the sea.

Ouch. 

And that's all for Hawaii's native reptiles. Every other slimy or scaly creature is an evil introduced hitch hiker, besides the rarely seen yellow-bellied sea snake which floats throughout the entire Pacific Ocean.

Aloha.

Graveyard Super Fun Time

I've come back with a terrible sunburn on my neck and a broken foot. Actually, I don't know if my foot is injured, but it kind of hurts when I walk. Regardless, I'm not into feet. I'm into lizards. They're so interesting that I'll spend all day in a graveyard in the middle of Queens observing and photographing them. Just another completely normal activity for a completely normal person.

Behold!

But these aren't your average lizards. Actually, they might as well be. They're greenish with a long tail, four legs and they're cool. But the killer is that these are lacertids! Which means they're in the family lacertidae! Which means they're originally from the Old World and have no reason being in the Americas. This is concerning because "introduced species are bad," but if you're an optimist  like me, it's really an amazing opportunity to study a species from a completely unique and distinct lineage that is normally unavailable here in the United States.

Apparently a pet shop in Long Island went out of business way back when and with great foresight let loose their stock of Italian wall lizards, Podarcis sicula. Despite New York being colder than their native Italy, the lizards did not die off in the winter, but proceeded to spread around Long Island and various parts of New York City. Someone should give that guy a medal or the key to the city or a Nobel prize. Whichever is the easiest to mail.

Another common name for these fine reptiles is "ruin lizard" because they're often found on rocky wall faces, but it seems that tombstones make a fine substitute. Also, as you may notice from the bit of Hebrew above, this was a Jewish cemetery making me even more of an oddball to see stalking through the graves with a lizard noose and DSLR. Here is a video detailing the habitat and me walking around contemplating whether or not I am disrespecting the deceased.

 

A lizard does make a quick, barely-visible appearance in this video.
Watch in 1080 and full screen for your best chance of finding it. 

These lizards were extremely abundant and it was hard not to walk a few steps without seeing or hearing one a two dash off into the vegetation or under a loose gravestone. Instead of amazing camoulfage, these lizards rely on their wariness and speed to escape from predators or lizard-crazy weirdos like me. This alertness is visible as you can see the lizard staring back at the camera in some photos.

As exciting as watching lizards run away from you can be (very) , lizards occasionally do other things too. One tried and true method to observe lizards behave naturally is to simply sit and wait for them to ignore your presence. As I sat on a conveniently placed bench nestled next to some graves, I was soon surrounded by a handful of lizards going about their business, although the lizard in the grave closest to me remained wary and only peeked his head out.

At this point in the day the lizards seemed to be bumming out in the shade, not doing much. But the stiff tension was broken when two large quarreling males brought their disputes to the ground next to my feet. The tail-less male below was being chased by another male with a complete tail. Unfortunately this was more of a chase than a fight, but it was an interesting moment of natural history. Who doesn't love those?!

If you have too much time on your hands and spent a good chunk of time staring at these pictures or reading about lizard biology, you may have noticed the difference in head size between photos. In this case, males have larger jaws relative to females presumably because they spend so much time fighting each other. Males with bigger heads have stronger bite force and defeat punier males and then proceed to take all the ladies, just like in humans. 

Not the best picture to highlight the differences, but the male is on the left. 

And as if you haven't had enough enthralling facts and pictures of lizards today, the peeling sunburnt skin on the back reminds me that lizards also shed. 

This is what my neck looks like. 

Wasn't that just wonderful and enlightening? Knowledge is power and power corrupts, so be careful.

The End of Summer

Well, the summer's over. Remember, it's a magical world and you should go exploring. It's been a good run.

Fine, the it's only mid-June and there's still plenty of good sunshine left to bring out the reptiles, but I'll be leaving the magical realm known as the temperate northeast for a while due to personal-medical-unemployment reasons AKA no actual reason at all. Actually I'll be going somewhere with many lizards. And then somewhere new with pretty lizards. More on that later. So before I leave here are some updates to the cliffhangers left by the last few taxonimically oriented posts to close out the end of the middle of the season.

Snakes: I have learned how to find snakes. I've found nine snakes since my last post. I am getting snake fever. I am no longer satisfied unless I find a snake.

Turtles: I found the box turtle. It was a very pleasant experience. I love turtles.

Salamanders: I got a shot of the red backed gerrymander with the added bonus of a worm. See if you can tell the two apart.

Frogs: are still omnipresent and I still take pictures of them.

The end. If you'd like to see my photographic progress from the whole season you can do so here. I've managed to produce 44 pictures in the month I've been exploring the badlands of the northeast, surpassing the 29 pictures I took in Florida. Yeah, yeah I was only in Florida for a week and there were way more reptiles, but despite the depauperate herpetofauna I've had a blast this past month getting to know the fauna of my childhood and what the buttons on my camera do.

Also, don't forget to submit your questions, comments, and criticism to the Super Fun 3000 Views Extravaganza Festival Q&A Party that is coming up once 3000 views are reached. This is thanks to all of you! Yes, even you spambots from Russia.

That's all folks!

Salamanders

If you asked me what my favorite group of animals was in elementary school I would have said salamanders. I think I've always wanted to focus on lizards, but they weren't around while salamanders were locally abundant and served as a superficial substitute. So I settled, but I was still the annoying kid who would harp on the differences if anyone were to generalize these two fundamentally different organisms. One key difference can barely be seen in the picture below:

Somewhere between the artsy fartsy-ness is a larval salamander in the genus Ambystoma. 

If you squint really hard there's an alien like creature floating towards the surface in the above picture. It has tiny toothpicks for hindlimbs and feathery plumes projecting from the back of its head to let it breath underwater. This may sound strange, but if you've ever played Pokemon this is the inspiration for Wooper and Mudkip. Except the design for Wooper is wrong because no salamander develops its legs before its arms. That's what frogs do. If you haven't played Pokemon and have no idea what I am talking about then I'm afraid there is nothing that can be done at this point (see hyperlinks).

Another reason why salamanders trump frogs in my unjust biased opinion is that all salamanders are born with a taste for blood. You'll never find a baby salamander being a wimp and scraping off some algae like some (but not all!) tadpoles. It's a general rule (in Jon's Guide to Cool Animals) that carnivorous animals are more interesting than herbivorous ones. Watching your pet lizard chase crickets is a lot more exciting than watching your pet tortoise chase a head of lettuce.

What are you looking at? You should be reading!

I could go on about the biology of salamanders for days, so I will. The next set of pictures illustrates the interesting life cycle of the interesting eastern newt. After the aquatic gilled Pokemon stage, this salamander goes onto land for two to seven years as a brightly colored " red eft" before finally going back to the water as an adult.

Devoted subscribers may notice I already used the bottom picture before.
Good thing I don't have any of those!

Efts are extremely abundant on the forest floor after rains and it can be hard to walk without squashing one every few steps. It's quite unusual to see a salamander strutting about so boldly in broad day light as most of them are secretive nocturnal creatures, but the efts are toxic and if you eat them you will die. Actually, I'm not sure if a human could be killed by eastern newt toxins, but their cousins in California are extremely toxic having killed a human (upon ingestion). Despite the potential harm to people, eastern newts are conducive for studies of limb and eye regeneration therefore of use to humans; which is really the point of biodiversity anyway.

Eastern newts are so cool because aquatic amphibians are cooler than terrestrial ones (see Jon's Totally Unbiased Guide to Cool Animals). Unfortunately the next salamander is not aquatic. It even went so far as to pop out miniature adults without gills severing its dependence on freestanding water although it still needs to live in moist environments because it doesn't have lungs and breathes through its skin. Imagine that.

You can barely see the lungs on this guy. 

So without further ado we have the slimy salamander AKA Plethodon glutinosus although sticky salamander is a more fitting name. It secretes a very sticky mucus upon being picked up by curious herpetologists. I've actually only heard about this species in the field guides of yore so I cried tears of happiness upon finding one under a rotting log. Actually I cried tears of sadness because the first one was extremely skittish and disappeared before I could get a good picture so I cursed the heavens and flipped everything in sight until finding another. 

Most woodland salamanders could easily be mistaken for a worm, but that's not the case for ye olde slimy sally-mander. This was a huge skink-sized beast of around six inches that could easily eat lesser manders for breakfast. One of these smaller salamanders is the omnipresent redbacked salamander whose accumulated biomass in a forest can be heavier than deer according to some studies which I do not have a picture of yet. This is a shame as this species was the first amphibian I ever saw. 

Thus ends Taxon Week as the weather is nice again and I won't be sitting on my computer all day. We're coming up on 3000 views which is just 11,239,232 views short of the average viral video, an important milestone nonetheless. To celebrate I ask you, the readers, to ask me whatever it is you wanted to know about this mysterious man of mystery who writes such inane posts. Comment below or send a letter to my estate. 

Frogs

Frogs are boring. They do not have tails, further removing them from the semblance of lizards and causing me to lose interest. Snakes are virtually an entire tail so they get a pass. Salamanders might as well be lizards unless you're a nerd. Turtles are unique, beautiful creatures and despite modifying their ribcage into a shell, they still have a tail. Tadpoles are great. Frogs are not. But they are amphibians so I'll still take pictures of them. And at the end of they day they're more interesting than dogs, monkeys, and mammals.

A green frog, but not a green frog.

So that's a bullfrog. As a seasoned reader of this blog you can probably see how it is a totally separate entity from the below frog, which is the completely different green frog. Gee, these entries sure have gotten into the habit of questioning the validity of species, at least with relevance to the average person. Louis C.K. sums it up pretty well.

A green frog, but it is rather brown.

But I must stick to my derpetologist roots and spearhead awareness of biodiversity. Obviously, you can tell these two species apart by the presence of dorsolateral ridges on the green frog which are absent on the bullfrog. In English, this means that there's a line that extends down the green frog's back visible in the above picture. In the bullfrog picture you can see how the ridge simply curls around the tympanum (the round thing; its what frogs use to hear) and extends downwards, not onto the back of the frog. Also, bullfrogs are huge. And they sound different. And their genomes probably have a bunch of differences. And the two frogs don't interbreed. But for the sake of easiness, perhaps we should just call all frogs "green frogs."

What better time to break the controversy with the first video of the season. I'm breaking into the educational nature video sector with this (extremely) short film to show you the differences between the calls of the two species in question. I imagined that simple frog calls by themselves would be a little dry so I added the most popular music on today's radios: jazz.

Watch in 1080!

Does it work? I don't know. You tell me. Either way, it's short and to the point. Anyway, let's celebrate the first video of the Magical Temperate Northeast project with everyone's favorite puzzle: Where's the Lithobates sylvaticus?

There is a frog here. Somewhere.
