Pharaonella
Pharaonella is a genus of marine snails, specifically sea slugs or nudibranchs, belonging to the family Chromodorididae. The genus was first described by Eliot in 1903. They are commonly referred to as chromodorids, and are known for their vibrant colors and intricate patterns. Pharaonella species are found primarily in the Indo-Pacific region, where they inhabit coral reefs and rocky shores.
Characteristics
Pharaonella species are characterized by their typically elongated, oval-shaped bodies. They are also known for their distinctive bright colors, often featuring shades of blue, yellow, and orange, sometimes with contrasting black or white markings. Their body is covered in cerata, small, finger-like projections that serve as both respiratory and defensive organs. These cerata can be highly variable in shape and color, adding to the diversity of appearances within the genus.
Environments
Pharaonella species are primarily found in the Indo-Pacific region, specifically in tropical and subtropical waters. They inhabit a variety of environments including coral reefs, rocky shores, and seagrass beds. These nudibranchs are often found among algae and sponges, which provide camouflage and a source of food. Pharaonella are active hunters, feeding on sponges and other invertebrates.
