Description

Biology

Etymology

  • Gibba. From Latin, hunch, because of the protuberance that runs along its dorsum and that differentiates it from other species. Colloquially it is called a “dromedary sea slug”.

Distribution
There are very few reports of this species since its description in 1951: two in the England’s South West, one in the western Mediterranean (Sea Slug Forum), two specimens in the island of Sálvora (Ria de Arosa, Galicia, Spain) and numerous specimens in the island Rúa (Ria de Arosa, Galicia, Spain) in what looks like a stable population in the area (GEMM).

Known georeferenced records of the species: Atagema gibba (z-200).
