Aphelodoris
Aphelodoris is a genus of sea slugs, specifically nudibranchs, in the family Dorididae. These colorful marine gastropods are known for their striking appearances, with bright and varied patterns and colors. While they can be commonly found in shallow intertidal zones, they can also be encountered in deeper waters.
Common Names
Common names for members of the Aphelodoris genus include:
- Aphelodorid nudibranchs
- Dorid nudibranchs
Characteristics
Aphelodoris species are characterized by their generally oval-shaped bodies, which are often flattened and wider than they are tall. They have prominent rhinophores, which are sensory organs that resemble small antennae. The gills, located on the dorsal side of the body, are arranged in a circle or a horseshoe shape. These nudibranchs have a distinctive feature known as a mantle, which is a flap of tissue that extends over the back and sides of the body.
Members of this genus are known for their wide range of color patterns, which often serve as camouflage or as a warning to potential predators. Some species, such as Aphelodoris brunnea, are known for their dull brown coloration, while others, such as Aphelodoris festiva, have bright and vivid colors and patterns. Their bodies are generally smooth and lack the cerata (finger-like projections) found in other nudibranch families.
Environment
Aphelodoris nudibranchs are typically found in marine environments with rocky substrates, often living among algae or sponges. They are carnivorous and feed on sponges, which they locate using their chemoreceptors. Some species prefer specific types of sponges while others are more generalist feeders.
