Feeding on or consuming seaweed, especially rockweed and related brown algae.
From Latin fucus (seaweed) combined with -vorous (devouring), from Latin vorare (to devour). A synonym to fuciphagous, formed through a different Latin root for eating. Both terms emerged in marine biology literature.
The term fucivorous appears in old zoology texts to describe animals like sea snails and certain fish, but it's almost identical in meaning to fuciphagous—it shows how scientists sometimes created overlapping terms from different Latin sources before standardizing vocabulary.
