The story of the word

βένθος is Homer's poetic form of βάθος, the deep. Ernst Haeckel put it to work in the 1890s as the opposite number to plankton, the drifters: benthos is everything that lives on the bottom or burrows into it. The two are not separate animals so much as separate ages, since a benthic crab spends its first weeks as a planktonic larva.
