Contents

Jorunna spazzola is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Discodorididae. [2]

Taxonomy

It is possibly synonymous with Jorunna luisae . [4]

Camacho-García et al. (2014) [5] suggested Caribbean animals identified as Jorunna spazzola could constitute a distinct species, because they display external differences with the original description from southern Brazil. [3]

Distribution

This species was described from Brazil. The distribution of Jorunna spazzola includes Florida, [6] Honduras, Costa Rica, Venezuela, Cuba, Curaçao, Barbados, Virgin Islands, Turks and Caicos, Brazil and Panama. [3]

Description

The body is oval. [3] The mantle is rigid. [3] Dorsum is flattened and covered with small caryophyllidia. [3] Branchial leaves are very short. [3] Background color is translucent gray with a few darker gray or brown patches over the dorsum. [3] Mantle margin is surrounded by small opaque white glands. [3] Rhinophores and gill are the same color as the rest of the body. [3] It is up to 18 mm long [3] or up to is 36 mm. [7]

According to Rudman (2008), this species is known mostly from internal characters and needs clarification. [8]

Ecology

Minimum recorded depth is 0 m. [7] Maximum recorded depth is 1.5 m. [7] It was found under rocks in Panama. [3]

Prey of Jorunna spazzola include sponges of the order Haplosclerida: Callyspongia pallida and Chalinula sp. [9] It is well camouflaged on its prey. [3] This species is able to quickly change colors as a response to unknown environmental cues. [3]
