Discodorididae

Common Names

Discodorididae are commonly referred to as discodorid nudibranchs or simply discodorids.

Characteristics

The defining characteristic of Discodorididae is the presence of prominent cerata, usually arranged in rows along the back. These cerata are often tipped with brightly colored spots, which can change depending on the species and their diet. These sea slugs also possess a characteristic mantle, which covers their dorsal surface. Additionally, they have a pair of rhinophores, sensory organs located on the head, and oral tentacles, used for feeding and sensing prey.

Environments

Discodorididae are primarily found in marine environments worldwide, inhabiting various habitats from shallow intertidal zones to deeper waters. They are often observed on rocky shores, coral reefs, and seagrass beds.

Diet

Discodorididae are carnivorous and feed primarily on sponges, incorporating the sponges' toxins into their own bodies as a defense mechanism. Their radula, a ribbon-like structure in their mouth, is adapted for scraping and tearing off sponge tissue.

Reproduction

Discodorididae are hermaphrodites, meaning they possess both male and female reproductive organs. They reproduce by laying egg masses, which are typically long, ribbon-like structures attached to rocks or other substrates.
