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.

Delicious!

    I'm not authorized to kill them; you need to be federally licensed in order to euthanize lab animals. I've dissected some already, but not from this set. Different university classes have access to different toads.

    Since these are for the animal development lab, I don't think that they'll get euthanized, but they might die anyway. The professor of that class usually offers to let the students keep any animals that survive by the end of the semester.

    Thanks, I know that not everyone likes them.

  16. I used to have a pond full of frogs and tadpoles. Herons used to come eat them.

    I loved that house. Wild deer would come into the garden. Literally a herd of wild deer.

  17. Great post Frog Guy. I love frogs and toads to bits. At work we have fire bellies. Only one left now though. I think he is going to die soon, I wanted to take him home so I could tend to it before it died. Although it would be interesting to see what's inside once he dies...yes that is a little morbid but I'm a scientist so what can you expect. :P Keep up the good work.

  20. You seem to know a lot about frogs... I got a frog about 8 years ago but I forgot what kind she is and I have no idea how to even begin to find out. Do you have any advice?

    Quite interesting! Followed.
