A spongivore is an organism that feeds primarily on animals of the Phylum Porifera, commonly called sea sponges.


The hawksbill turtle is one of the few animals known to feed primarily on sponges. It is the only known spongivorous reptile.[1] Sponges of various select species constitute up to 95% of the diets of Caribbean hawksbill turtle populations.[2]

Pomacanthus imperator, the emperor angelfish, is a known spongivorous coral reef fish.[3][4]

Certain species of nudibranchs are known to feed selectively on specific species of sponges.
