Ophioglossolambis violacea is a species of marine snail found in the Indian Ocean . Occasionally it is called purple spider snail with its German name.

Appearance

Ophioglossolambis violacea has a bulbous housing with an enlarged outer lip that can carry 15 to 17 processes. The siphon channel is long and curved towards the mouth. The power bus notch is wide and deep. The spiral strips run the entire height of the case, and on the younger turns they have nodules at irregular intervals. The mouth has delicate ridges. The ledges are strongest on the attachments. The color is white with brown spots and welts. Characteristic and name-giving is the whitish, inside pale purple-red coloration of the mouth (strong purple stripes, inside yellowish in Ophioglossolambis digitata ). The outer lip has orange spots. The case can be 7 to 11.5 cm in size.

distribution

This snail species is widespread in the western Indo-Pacific , they only live on the Mascarene Plateau in moderately deep water around the islands of Réunion and Mauritius . A statement from Indonesia is very likely due to confusion.

It is not known for sure whether the species is threatened. Hazard according to IUCN: DD (data deficient). But there are indications that the attractive species is endangered by overcrowding.

Taxonomy

The species was first described as Pterocera violacea by William Swainson and transferred to the newly established genus Ophioglossolambis by Aart M. Dekkers in 2012 . The generic name is derived from the genus Lambis . It is supplemented by a reference to the last tooth of the lip, which is split and therefore reminded the descriptor of a snake's tongue (from Greek ophios: snake and glossa: tongue).
