Morphology

marine + benthos

The meaning is directly compositional: 'marine' (sea-related) + 'benthos' (organisms living on the seafloor) together denote organisms living at or near the bottom of the sea. This is a literal, non-idiomatic formation found across languages, so a B1 learner who knows both constituents can infer the MWE meaning.

Etymology

Marine benthos uses benthos, an old word for the 'sea bottom' or 'depths', and marine means 'sea'. So marine benthos literally names the plants and animals that live on or near the sea floor, which is why it means organisms at the bottom of the sea.
