Rumphella

Common Names

While not as widely known as some other nudibranchs, members of the Rumphella genus are often referred to by their common name, "Chromodorid nudibranchs." This name reflects their close relationship with the family Chromodorididae.

Characteristics

Rumphella species share several defining characteristics:

• Dorso-ventrally flattened body: This allows them to easily navigate crevices and amongst coral.
• Cerata: These are finger-like projections extending from the mantle, which serve as respiratory organs and may also contain nematocysts (stinging cells) acquired from their diet.
• Rhinophores: These are sensory organs located on the head, helping them detect food and navigate their environment.
• Bright and varied coloration: Rumphella species are often characterized by vivid colors, including reds, oranges, yellows, blues, and greens. This coloration may serve as camouflage, warning signals, or for species recognition.

Environments

Rumphella species are typically found in tropical and subtropical waters, often in coral reefs and rocky areas. They are primarily found in the Indo-Pacific region, with some species also found in the Caribbean Sea.
