Contents

Geitodoris planata is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Discodorididae.

Taxonomy

It was originally described from Europe. Caribbean populations are morphologically similar but almost certainly distinct. [5] Alvim & Pimenta (2013) [6] regarded Caribbean animals as Geitodoris pusae (Er. Marcus, 1955), but no molecular studies have been conducted to compare animals from both sides of the Atlantic Ocean. [5] Further research is necessary to clarify the status of this species. [5]

Distribution

Distribution of Geitodoris planata includes Mediterranean Sea, North Atlantic Ocean, North Sea, Western Atlantic: New Jersey, St. Lucia and Panama. [5]

The type locality is "Lamlash Bay", Isle of Arran, Scotland. [1]

The body is oval. [5] Mantle is rigid. [5] Dorsum is covered by rounded, stalked tubercles. [5] Background color is grayish-brown with some dark brown irregular patches. [5] The color fades and becomes more translucent towards the mantle margin. [5] Larger tubercles surrounded with opaque white pigment. [5] Rhinophores and gill are usually the same color as the dorsum with white tips. [5] The maximum recorded body length is 65 mm. [7] [5]

Ecology

Minimum recorded depth is 91 m. [7] Maximum recorded depth is 267 m. [7] But this species apparently live also in more shallow water. [5] It was found in coral rubble in a predominately sea grass habitat in Panama. [5]

Its prey include sponges Hemimycale columella and Hymeniacidon perlevis . [8]
