Cadlinidae

Cadlinidae is a family of colorful and diverse sea slugs, commonly known as cadlinid nudibranchs. These marine gastropods are found in a variety of habitats, from shallow rocky shores to deeper, colder waters. They are characterized by their slender, elongate bodies, often adorned with intricate patterns and vibrant colors. They are carnivorous, feeding mainly on sponges and bryozoans, and play an important role in the marine ecosystem.

Common Names

Cadlinidae are commonly known as cadlinid nudibranchs. They are also sometimes referred to as cadlinids or cadlinid sea slugs.

Characteristics

Cadlinid nudibranchs are characterized by the following features:

  • Slender, elongate body: They typically have a long, thin body that is often tapered at both ends.
  • Branched rhinophores: Their rhinophores, which are sensory organs used to detect food and other stimuli, are usually branched or digitate.
  • Cerata: They possess cerata, which are finger-like projections along their back, that can be used for respiration and defense.
  • Vibrant colors and patterns: Cadlinids are known for their striking colors and complex patterns, often featuring combinations of red, orange, yellow, green, blue, and purple.
  • Carnivorous diet: They primarily feed on sponges and bryozoans, using their radula, a ribbon-like structure with teeth, to scrape off the food source.

Environments

Cadlinidae are found in a variety of marine environments, including:

  • Shallow rocky shores: They are often found in tide pools and on rocky outcrops in the intertidal zone.
  • Subtidal reefs: They can also be found on coral reefs and other subtidal habitats.
  • Deep-water environments: Some species of cadlinids have been found in deep-sea environments.
