There are so many animals that possess many astonishing qualities that we can learn form or which play a role as a keystone species determining the types and numbers of various other species in a community.
Some enjoy the ideal hydrodynamic form to allow them to move through water others have the most amazing sensory perceptions.
Thanks to the science of biomimicry, products emerging from the imitation of these features. For example, scanning electron microscope studies have revealed that tiny "teeth" (riblets) cover the surface of a sharks’ skin that produce vertical vortices or spirals of water, keeping the water closer to the shark’s body and thus reducing drag. This led to the development of new swim wear.
There are loads more examples I could give, but here are ten for starters:
