If you’ve ever watched 
Planet Earth, you know the ocean is a wild place to live. The water is teeming with different ecosystems and organisms varying in complexity from an erudite octopus to a sea star. Unexpectedly, it is the sea star, a simple organism characterized by a decentralized nervous system, that offers insights into advanced adaptation to hydrodynamic forces the forces created by water flow.
Researchers from the USC Viterbi School of Engineering found that sea star body shapes enable them to effectively stay attached to surfaces under extreme hydrodynamic loads. The researchers, including the Henry Salvatori Early Career Chair in Aerospace and Mechanical Engineering Mitul Luhar and doctoral student Mark Hermes, found sea stars create a “downforce” due to their shape. This means that instead of being lifted by the flow forces, the sea stars are pushed downw ....
