Chondrocladia sponge

Although it looks like something out of a Dr. Seuss book, this is a deep-sea sponge in the genus Chondrocladia. A little over 30 centimeters (1 foot) tall, this sponge was photographed by MBARI's ROV Tiburon about 2,555 meters (8,400 feet) below the ocean surface, in the Gulf of California. Unlike many sponges, which obtain food by filtering microscopic particles from seawater, Chondrocladia sponges capture and digest small shrimp and other crustaceans that stick to the sponge's translucent globes.
