Dendrodorididae
Dendrodorididae is a family of colorful, often strikingly patterned, sea slugs belonging to the order Nudibranchia. They are commonly referred to as dendrodorids, and are closely related to other families like the Chromodorididae. These marine gastropods are known for their diverse forms, ranging from small and slender to large and flattened, and their bright coloration often serves as a warning to potential predators about their toxicity.
Common Names
Dendrodorididae are often simply called "dendrodorids." However, some species might have specific common names, such as the "ringed dendrodorid" for Dendrodoris fumata.
Characteristics
Dendrodorids share several distinctive characteristics:
- Body shape: They typically have an elongated, flattened body with a distinct head, a prominent mantle, and a tail.
- Coloration: Often brightly colored with striking patterns, frequently including bright red, orange, yellow, and black.
- Rhinophores: Their sensory organs, called rhinophores, are club-shaped and often branched, providing a heightened sense of smell for finding food.
- Cerata: These fleshy, finger-like projections, called cerata, arise from the back and sides of the body. They can be smooth or have various textures, and play a role in respiration and defense.
- Toxicity: Many dendrodorids produce toxic compounds that make them unpalatable to predators. This defense mechanism is often indicated by their vibrant coloration.
Environment
Dendrodorids are found in tropical and subtropical waters worldwide. They are typically associated with coral reefs, rocky shores, and seagrass meadows. They are often observed crawling on the seabed, actively foraging for food, or clinging to substrates.
Diet
Dendrodorids are carnivorous and primarily feed on sponges. Some species may also consume other invertebrates such as tunicates and hydroids.
Reproduction
Dendrodorids reproduce sexually, with internal fertilization. They lay eggs in long, spiraled strings or coils, often attached to rocks or other surfaces.
