Akera
Akera is a genus of sea slugs, marine gastropod mollusks in the family Akeridae. These small, slender gastropods are commonly known as “bubble shells” due to their translucent, bulbous shells. They are characterized by their distinctive, oval-shaped shells with a distinct aperture and a sharp, pointed apex. The shell often has a smooth, glossy surface and may exhibit various colors, including white, yellow, brown, or reddish-brown.
Characteristics
Members of the genus Akera are primarily herbivorous and feed on a variety of marine algae. They possess a radula, a ribbon-like structure with rows of teeth, which they use to scrape algae off surfaces. They also have a pair of tentacles that extend from their head, which function as sensory organs to help them locate food and navigate their environment.
Environment
Akera species inhabit a wide range of marine environments, including coastal waters, estuaries, and open ocean habitats. They are typically found in shallow waters, often associated with seagrass beds, rocky shores, and sandy bottoms.
Distribution
These sea slugs have a global distribution, with species found in various oceans around the world. They are particularly abundant in temperate and tropical regions, where they thrive in warmer waters.
