Sounds kind of like an oxymoron doesn’t it? Who knew sponges could be carnivorous? Scientists have described four new species of carnivorous sponges in a newly published article in Zootaxa. Check out this video from the lead author of the study, Lonny Lundsten who is a Senior Research Technician at the Monterey Bay Aquarium Research Institute:
Lundsten L, Reiswig HM, Austin WC. Four new species of Cladorhizidae (Porifera, Demospongiae, Poecilosclerida) from the Northeast Pacific. Zootaxa. 3786 (2): 101–123, 2014.
