Stomozoidae
Stomozoidae is a family of sea slugs, specifically nudibranchs, belonging to the order Nudibranchia within the class Gastropoda. They are distinguished by their unique morphology and feeding habits, making them a fascinating group within the diverse world of marine invertebrates.
Common Names
Stomozoidae members are commonly known as "dorid nudibranchs" due to their characteristic dorsal (back) surface covered in prominent, often brightly colored, cerata.
Characteristics
Stomozoidae species share several defining features:
- Cerata: These are finger-like projections on their dorsal surface, which serve as both respiratory and defensive organs. They often contain stinging nematocysts obtained from their prey.
- Rhinophores: These are sensory organs located on the head, used to detect chemical cues and food sources.
- Mantle: A fleshy covering that protects the internal organs and often has a distinct shape or pattern.
- Gill: A single, feathery gill located beneath the mantle, used for respiration.
Environment
Stomozoidae are found in various marine environments, primarily in the Indo-Pacific region, but also in the Atlantic and Mediterranean. They are typically associated with coral reefs, rocky shores, and seagrass meadows.
Feeding Habits
Stomozoidae are carnivorous and feed on a variety of sessile invertebrates, including sponges, hydroids, and bryozoans. They capture their prey using their radula, a rasping tongue-like structure, and extract nematocysts from their prey to incorporate into their own cerata for defense.
