Phyllidia

Phyllidia is a genus of colorful sea slugs, commonly known as Phyllidiid Nudibranchs, belonging to the Phyllidiidae family within the order Nudibranchia. They are characterized by their flattened, oval bodies, which are covered in numerous, prominent tubercles. These tubercles are often brightly colored and can vary in size and shape depending on the species. Phyllidia species are predominantly found in tropical and subtropical waters throughout the Indo-Pacific region.

Characteristics

Phyllidiid Nudibranchs are known for their striking color patterns and texture. They typically lack gills and rhinophores, the sensory organs common in many other nudibranchs. Their bodies are covered in a thick, leathery mantle that provides protection and camouflage. Some species have raised tubercles with distinct markings, while others have smooth, shiny surfaces.

Environment

Phyllidia species are primarily found in shallow, coastal waters, often in areas with abundant coral reefs or rocky substrates. They are commonly observed on algae, sponges, and other invertebrates. These nudibranchs are carnivores, feeding on sponges and other benthic organisms.

Common Names

Phyllidia species are commonly known as:

  • Phyllidiid Nudibranchs
  • Sea Slugs
  • Phyllidiid Flatworms
