These are western pond turtles (Emys marmorata), California’s only native freshwater turtle. They are also tiny and adorable right after they hatch (yes I am a scientist I have data to prove this). 😀 These babies were incubated in their nests (at my field site), and the eggs were collected last week, so they could hatch in the lab. They’ll be raised for either one or two years at one of three local zoos, before being released back into the wild.

Western pond turtle. That protrusion on the belly is the turtle’s external yolk; this is normal, and will be absorbed into its body during the next few weeks.

I AM SCIENTIST therefore I record data on paper towels. What, doesn’t everyone do this?

Literally just hatched.

Our incubators. Reasonably low tech, but they get the job done. OH LOOK more paper towels.

Precious babby. They are so tiny when they first hatch. I’d say on average they’re about 4 to 4.5 grams. This one is not even 4 grams (although the one in the first photo was big – almost 6).

And … as of a few hours ago, my field season for this year has officially ENDED. I didn’t think I was even going to find any turtles today, but then, at the tail end of my last walkthrough, I found this gorgeous lady, JUST after she finished nesting (which is the absolute best time to find them, for a bunch of different reasons). So, YAY Turtle #261! My last turtle of what might be my last official field season on this project. Isn’t she the prettiest princess EVER?

Overall, it was a weird field season. We didn’t find nearly as many nests as in previous years, and we never really had a “peak” – there is usually a week or so when LOADS of turtles are all out on the same days; I think the most we ever had on a single day this year was five. I attribute this mostly to the weather (which alternated between rainy and cold, which they won’t come out to nest in, and EXTREME heat, which they also won’t come out to nest in). But, it was still fun, although I will say I’m glad it’s over. I get a bit tired of camping two or three nights a week.

TURTLES! We found four of them last night. This one is #248. AND SHE IS THE PRETTIEST PRINCESS IN PRINCESS TOWN! She was really adorable, too. She stuck her head out while we were taking photos.

Don’t know if we’ll see any turtles tonight. Weather is all over the place here; we had a MASSIVE thunderstorm last night, and a bit of rain. They won’t come out to nest unless the ground is dry, so if it rained too much at the field site, tonight will be dead up there. But we’ll see. Either way, TURTLES!!!!!!

Some western pond turtle photos! Brand new babies, hatched in my lab:

Eventually, they’ll be head-started at a local zoo until they’re about 10 months old, at which time they’ll be released back into the habitat where we collected the eggs. The first picture is of a baby working on getting out of her shell. And the third picture was taken literally seconds after she emerged from her shell. (I was too slow with my camera, or I could have gotten it on video. I’m hoping one of the other babies will oblige; we still have a lot of eggs that have yet to hatch). Also, sorry the photos were so crappy. I need to bring in my real camera and get some better shots.

WE HAVE A BABY!!!!!!! Just one so far … but this is only the beginning.

See this? This is a turtle egg. This is a turtle egg with a hole. Do you know why it has a hole? Because the baby turtle is TRYING TO GET OUT! WHOO HOO! We call this “pipping,” and it means that sometime in the near future – maybe even tonight – THERE WILL BE A BABY TURTLE HATCHED IN MY LAB! 🙂 🙂 🙂
