Quite possibly the angriest animal met all year. As soon as my professor saw it, he ran into that muck you see in the background(which in some places was deep enough to pull your entire foot in) and grabbed him. Also, I can assure you, that is the safest way to hold a snapping turtle, both for the handler and the turtle. Holding them by their legs is fine, so long as you don't hold them by the tail. We held him for maybe 20 seconds to get the picture then set him down. He kinda hissed at us before walking maybe 2 feet away and burying himself in the muck. By the time we left, he had completely submerged himself, which was interesting to watch.

The aforementioned angry snapper, moments before he began sinking into the muck.

Dragonfly larvae if I'm not mistaken. These guys were literally everywhere when we were drop netting. You should thank them for their service, as they are the main reason mosquitoes don't swarm around temporary ponds. These little guys are the alpha predators of the puddle.

Slithery and cute, but also very angry because we almost stepped on him. He was just sunbathing in the middle of the trail. After we put him down he glared at us for a while before making a break for it.

Another angry dude who got pissed at us for disturbing his peaceful napping spot...directly in the middle of a common running path. We slid him off to the side just in case.

A big ol' tadpole. Don't worry, we put all of them back. There was even a middle school fieldtrip happening nearby so we got to show some kids a bunch of tadpoles and frogs.

This little guy was fished out of a pond and actually posed for us. We thank him for his patience.

Some cute little Two-lined Salamanders IIRC. These guys are everywhere if you know where to look. Under rocks near the edges of streams, yet not in running water. Careful when handling though as they do secrete toxins. Nothing dangerous enough to get through your skin, but make sure you don't rub your eyes after holding one.

What a photogenic frog.

The pudgiest newt you ever saw. I wanna say it's a spotted newt, but can't say for certain. I'll probably just use the general term salamander.

Newt making a break for it.

Just for everyone's peace of mind: We made sure to release everything we caught(even the little bugs we fished out with nets) and put them all back under the rocks we found them in the case of newts/salamanders. We were doing a survey to assess species diversity in streams of varying urbanization levels. Photos are a courtesy of all of my classmates as our professor wanted to thoroughly document our field trips.

No this is the pudgiest newt you ever saw!

I'm scared of the US nature. Can't be worse than Australia, but I'm scared. Thank God Europe is so save and filled with fluffy animals.

Snapping turtles are mean, angry assholes

8 years ago | Likes 1 Dislikes 0

Some are, many are just scared though since they can't fully retreat into their shells like other turtles, so they have to be aggressive.

No problem! Was probably my favorite lab of all time, so thought it'd be cool to share.

Very cool! Did you also test the water quality based on animal diversity?

The last two pics are of the eastern red spotted newt. They have a super cool lifecycle, and are poisonous but only if you chew them.

8 years ago | Likes 1 Dislikes 0

Also I don't think those are two lined slamanders. Usually their stripes are very prominant while these are mottled and have different tails

But maybe thats just the variatiom where I am and they look different wherever you are. Great finds though!!!

What's the dark triangle on the tail of the newt in the last picture?

7 years ago | Likes 1 Dislikes 0

The two lined salamanders and the spotted newt are both eastern newts.

Hold those snappers above and in front of the back legs on the shell using your knuckles to keep the legs down and claws from scratching you

I used to catch snapping turtles all the time at my moms! Suckers get HUUUGE but are super cute as babies and stop biting after a few mos.

Don't have to be a bio major. Unless you're going into Marine or Ecology, Aquatic Bio really isn't a requirement for most degrees. I took it

Those are critters I've been catching since I was 5. That's awesome.

Yep! It's really surprising how when you first start you can't imagine there being so many, but once u know where to look they've everywhere

In the name of science! We got some good data specifically on how urbanization affects two common salamander species in our area.

8 years ago | Likes 12 Dislikes 0

Care to elaborate on your findings? This is super interesting stuff.

8 years ago | Likes 1 Dislikes 0

To sum it up, urbanization negatively impacts both species of salamanders(Dusky and Two-Lined), however as urbanization decreases you 1/n

8 years ago | Likes 2 Dislikes 0

get significantly more Dusky than Two-lined, as the Duskys aren't as resistant to the effects of urbanization, so they survive better in 2/n

8 years ago | Likes 2 Dislikes 0

heavily forested streams. Two-lined salamanders tolerate urbanization more so more urban streams have almost exclusively 2-lined salamanders

So then is that thing about "don't touch amphibians with your bare hands cause their skin is absorbative and it'll poison them" a myth?

8 years ago | Likes 1 Dislikes 0

It's probably dependent on exposure time. I'd imagine handling amphibians with much more toxic secretions could potentially be dangerous.

8 years ago | Likes 1 Dislikes 0

From what I gather most of their toxins are only deadly if they are in high quantities, like through direct blood or mucosal exposure

8 years ago | Likes 1 Dislikes 0

Need to rephrase... I've always been told that our skin is harmful to them. Just wondering if that's true

8 years ago | Likes 1 Dislikes 0

Oh that. As long as you don't have like bug repellent, lotions or cleaning products on your hands, they should be fine. It'd probably 1/2

8 years ago | Likes 1 Dislikes 0

only be an issue if you were constantly holding them, but even then, stress would probably be more dangerous than any oils or dirt.

As a field ecologist that works with snappers every summer, i find picking them up by the shell works better. They can only snap as far(1/?)

8 years ago | Likes 3 Dislikes 0

Back as their hind legs so if you grip the shell on either side of the tail behind the legs its far more comfortable for the turtle. If(2/?)

8 years ago | Likes 3 Dislikes 0

You're travelling far with them you can also slide a hand underneath their bottom shell and hold like a dinner plate while using the (3/?)

8 years ago | Likes 3 Dislikes 0

Other hand on the back of shell as a guide. They cant snap down! Plus then you're using your arms and not your wrists for extended periods.

8 years ago | Likes 3 Dislikes 0

Love these little nuggets. They arent mean, just snap when they're scared cause they cant hide in their shell! <3

8 years ago | Likes 1 Dislikes 0

That's good to know. I have a feeling my professor was afraid of dropping him since his shell was completely covered in mud.

8 years ago | Likes 2 Dislikes 0

Understandable. We do capture-mark-release with them in Ontario and they can be a bitch to catch in the bog! :P Slippery buggers...

What's the difference between Aquatic Biology and Marine Biology?

8 years ago | Likes 32 Dislikes 1

Fresh water is aquatic & marine is saltwater.

8 years ago | Likes 2 Dislikes 0

Salt

8 years ago | Likes 8 Dislikes 0

I think marine is the ocean, and aquatic is more water I general. But I'm not an expert.

8 years ago | Likes 7 Dislikes 0

You're correct. Aquatic could mean marine or freshwater, but our lab only focused on the freshwater aspect.

8 years ago | Likes 5 Dislikes 0

Marine is technically a subcategory of Aquatic Biology. For the purposes of this course though, it just means freshwater only.

8 years ago | Likes 51 Dislikes 1

So we worked out way from small temporary water like tree-holes, cups, etc into temp ponds, streams, lakes, rivers and stopped at estuaries

Is there a difference from limnology?

8 years ago | Likes 2 Dislikes 0

As I understand it,the only differences might be that we covered estuaries.Limnology would include saltlakes too, but we only did freshwater
