When scientists reached the hydrothermal vents they found them teeming with life. 1988. At the same time early European settlers, oblivious to the "protein-rich coasts" all about them, starved from lack of protein. “A new species of Rimicaris (Crustacea: Decapoda: Caridea: Alvinocarididae) from hydrothermal vent fields on the Mid-Cayman Spreading Centre, Caribbean.”, [3] Lee Van Dover, Cindy, Ete Z. Szuts, Steven C. Chamberlain, and J.R. Crann. Twitter. Historically, it was the distinction between walking and swimming that formed the primary taxonomic division into the former suborders Natantia and Reptantia.
