Crimora

Crimora is a genus of sea slugs, specifically nudibranchs, in the family Polyceridae. They are found in the Northeast Atlantic Ocean, the Mediterranean Sea, and the Northwest Pacific Ocean. Crimora species are notable for their bright, often colorful bodies and their distinctive rhinophores (sensory organs) that resemble feathers.

Common Names

Crimora species are commonly referred to as "feather-duster nudibranchs" due to the appearance of their rhinophores.

Characteristics

Members of the genus Crimora typically share several characteristics:

  • Rhinophores: Feather-like rhinophores, often branching and covered in papillae.
  • Body: Usually small to medium in size, with a soft, fleshy body.
  • Coloration: Often brightly colored, displaying combinations of red, orange, yellow, white, and brown.
  • Cerata: Some species may have cerata (finger-like projections) on their dorsum, but these are not as prominent as in other nudibranch families.

Environment

Crimora species are typically found in shallow, coastal waters, often associated with rocky reefs, seaweed, and sponges. They are carnivorous, feeding primarily on hydroids (small colonial animals) and other invertebrates.
