Summer Mudpuppies

CMNH Curator of Vertebrate Zoology Dr. Tim Matson and his interns spent a morning with the Future Scientists showing how they did their mudpuppy studies. One factor that they are tracking is the effect of lampricides (to get rid of non-native lampreys) on these aquatic salamanders.

Mudpuppy! The Future Scientists were extremely fortunate to witness the only adult that was found the whole day.

One nest of mudpuppy larvae was also found. Here you can see the yolk sac on the ventral side of one of the salamander babies.
