Yes, I have a BS in ecology and an MS in conservation biology, and am working on a PhD in soil, water, and environmental science. I knew that shrimp molted but didn't know that their entire "shape" stayed intact, with their antennae, claws, and legs all in one piece. So, no, I am not a marine (or even animal) biologist and I apologize for not knowing everything about every type of living creature in spite of my degrees :mrgreen:
Sometimes the knowledge and skills that one uses in their everyday professional life does not transfer over or apply to keeping exotic animals in artificial environments in their dining rooms :D That's why I come to this forum for help. No hard feelings though, I may be a biologist that doesn't know about shrimp, but at least I have a friendly place to go with my questions where other people seem to know lots about shrimp.
