Questions for Hellbenders

Fri, 2015-02-06 08:00
SCIENCEBefore reading:1.    How is an amphibian different from a fish or a reptile? Name three kinds of amphibians.2.    Why is clean water necessary for animals and for people?During reading:1.    What is hellbender “snot,” and how does it help a hellbender?2.    What happens to a hellbender during its metamorphosis?3.    How many subspecies of hellbender exist? Give their names and where they can be found.4.    A pair of hellbenders can produce hundreds of larvae. Why doesn’t that result in hundreds of adult hellbenders?5.    Why is silt and sediment washing into waterways where hellbenders live?6.    Name three threats that hellbenders face.7.    What are hellbender head-start programs, and how do they work?8.    Why are researchers careful to not release too many sibling hellbenders into the same area?
