Souverbi's Lobiger

Lobiger souverbii


Lobiger souverbii is a species of small sea snail or sea slug, a marine gastropod mollusk in the family Oxynoidae. They are small sacoglossid, found primarily on the green algae, Caulerpa. It has retained an external shell which is semi-transparent. Like other sacoglossids it has rolled rhinophores. This species is characterized by its four long parapodial lobes, which often are seen rolled up like the rhinophores. These extensions of the mantle may become severed or autotomized when the animal is disturbed. This has led to some confusion, with several species (an in fact the original description of Lobiger souverbii) being described as having only two lobes. The body is green, making it difficult to find on its algal food source, with varying amounts of lighter speckling. The surface texture found on the foot and tail, also occurs on the lateral lobes and rhinophores.

Pic #3 shows the organism among its food plant. Although from the pictures, you can see the organism clearly, but due to its small size of around 2 cm, they are actually quite well camouflaged and the lobes is supposedly imitates the branches of the algae making them very difficult to spot.

Thanks, @Leuba, @Mark & @Marta.
Don't mean to exaggerate, but will not be surprised if many avid divers/underwater photographers have not seen this too :D
They are actually hard to find, even when you locate the Caulerpa algae.
