Poison dart frogs are known for their toxicity, but only a few are actually harmful to humans. This knowledge may be fundamental in bioprospect research in hopes that it could help out humans in one way or another. Amphibians make up a large percentage of the biomass and their decline may have a significant impact upon other species in the ecosystem (Daszak, Berger, and Cunningham, 1999). These frogs have bilateral symmetry which means … Strawberry poison dart frogs are fragile dart frog species as compared to other frogs. A strawberry poison frog in Guayacan, Costa Rica, in 2011.
