Etymology

Origin of subaquatic

First recorded in 1780–90; sub- + aquatic

Explanation

A subaquatic creature lives or exists entirely under water. A squid cruising the ocean depths or a clam buried in the seabed both fit the bill. Subaquatic creatures like octopuses, jellyfish, and starfish spend their whole existence below the surface. The word often shows up in marine biology texts, but you might also see it describing things like subaquatic caves or plants. Subaquatic is derived from the Latin sub, "under," and aquatic, "relating to or operating in water."
