Thorunna

Thorunna is a genus of sea slugs, specifically nudibranchs, that are marine gastropod mollusks within the family Chromodorididae. These colorful creatures are known for their distinctive, often flamboyant, color patterns and their relatively small sizes.

Common Names

While most species within the genus Thorunna lack common names, some are known as "Thorunna nudibranchs" or "Thorunna sea slugs".

Characteristics

Thorunna species exhibit a wide range of colors and patterns, with some species sporting vivid shades of orange, red, purple, and blue. They typically possess a soft, elongated body with prominent rhinophores (sensory organs) and cerata (projections on their backs). These cerata often house symbiotic algae, which may contribute to their distinctive coloration.
