The Acute Kaloplocamus, Spiky Kaloplocamus, or Pointed Kaloplocamus (scientific name: Kaloplocamus acutus) is a fascinating species of sea slug belonging to the family Polyceridae. This nudibranch is known for its distinctive spiky appearance and its specialized diet of bryozoans.
Description & Characteristics
Kaloplocamus acutus is characterized by its elongated, slender body, which can reach a maximum size of around 10mm. Its body is covered in numerous, prominent, conical tubercles, giving it its characteristic “spiky” appearance. These tubercles are typically a pale white or cream color, contrasting with the darker background coloration of the body, which can range from pale brown to dark brown or even reddish-brown.
Habitat and Occurrence
Kaloplocamus acutus prefers habitats that are rich in bryozoans, its primary food source. This means that it is commonly found in shallow, coastal waters, particularly in the intertidal zone and on rocky reefs. Kaloplocamus acutus is found in the temperate waters of the North Atlantic Ocean, making it a common sight in the marine ecosystems of this region.
Taxonomy
Kaloplocamus acutus belongs to the family Polyceridae, a group of sea slugs known for their diversity and specialized diets. This family is part of the order Nudibranchia, which is a group of marine gastropods that lack shells and are known for their vibrant colors and fascinating forms. The Nudibranchia, in turn, belongs to the larger class Gastropoda, which includes a wide variety of mollusks such as snails, slugs, and sea hares.
Feeding
Kaloplocamus acutus is a specialist feeder, meaning that it relies on a very specific diet. Its primary food source is bryozoans, also known as “sea mats.” These small, colonial animals often grow in dense mats on rocks and other surfaces, providing a readily available food source for Kaloplocamus acutus.
