Common Names

Kraussinidae snails are often referred to as "kraussian nudibranchs" or simply "kraussinids." However, they lack widespread common names due to their relatively small size and restricted distribution.

Characteristics

Kraussinidae snails exhibit several distinctive characteristics:

  • Body Shape: Generally elongated and slender, with a flattened, leaf-like appearance.
  • Cerata: Possess numerous, finger-like projections called cerata that are densely packed along the dorsal surface of the body. These cerata are used for respiration and sometimes for defense.
  • Coloration: Often display vibrant and contrasting colors, including shades of red, orange, yellow, green, and blue.
  • Size: Relatively small in size, typically ranging from a few millimeters to a couple of centimeters in length.
  • Diet: Primarily feed on hydroids, which are colonial animals belonging to the phylum Cnidaria. They extract stinging nematocysts from their prey, which they use for defense.

Environments

Kraussinidae snails are typically found in shallow, coastal waters, often associated with rocky reefs, seaweeds, and other benthic habitats. They prefer areas with moderate water flow and ample food sources.
