Building Mussels

This is a fantastic video produced by Defenders of Wildlife. The video talks about things that are being done today to help restore freshwater mussel populations and why these shelled invertebrates are so important. The comprehensive effort is bringing back many species from the verge of extinction as well. In particular, they mention some of the endangered species that they have actually been able to successfully breed in a controlled setting.

Be careful watching though... you just might learn something!
