Tadpole day!

Sorry, I forgot to take my camera with me to work yesterday. Some of the toads were still in their feeding tanks (even though I know I fed them yesterday...), so here's a pic of them:

These are three male fire-bellied toads. The little guy in the middle is albino. He didn't seem to be feeling well yesterday (wouldn't eat or swim), so my guess is that they're staying in the feeding trays as a temporary quarantine until they get a tank set up.

Anyway, to the tadpoles. The set I've got here are juvenile Bombina orientalis, which are probably used in the animal development lab. Their tank's a mess, so they'll be staying in these feeding trays until the cleaning crew is done.


That's what their water looked like before I got there. Yuck! The whole tank was like that...
Amphibians are very sensitive to ion content in water, which is why they're often considered measures of a watershed's health-- any change in the water will visibly affect amphibian populations. As such, we're very careful about the water we use in the lab. All tanks are cleaned with deionized water. The tadpoles also live in a solution of 90% deionized water and 10% Holtfreter's solution.

Here are the tadpoles in their new, clean trays:


I also gave them enough lettuce to tie them over until next time.

From the lab.

Hello! I work in a biology lab. Though I mainly take care of Bombina orientalis, there are other types of amphibians in the lab as well.

 Here's a tree frog:

 Here are some fire belly toads:

 A tray of tadpoles! This is only one of many. Whereas the toads are mainly used for breeding, the lab can have hundreds and hundreds of tadpoles.

Next time, I'll upload some pictures of the toads feeding.
