Marcus, 1963 }}Jorunna spazzola is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Discodorididae.[2] TaxonomyIt is possibly synonymous with Jorunna luisae.[3] Camacho-García et al. (2014)[4] 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] DistributionThis species was described from Brazil. The distribution of Jorunna spazzola includes Florida,[5] Honduras, Costa Rica, Venezuela, Cuba, Curaçao, Barbados, Virgin Islands, Turks and Caicos, Brazil and Panama.[3] DescriptionThe 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.[6] According to Rudman (2008), this species is known mostly from internal characters and needs clarification.[7] EcologyMinimum recorded depth is 0 m.[6] Maximum recorded depth is 1.5 m.[6] It was found under rocks in Panama.[3] Prey of Jorunna spazzola include sponges of the order Haplosclerida: Callyspongia pallida and Chalinula sp.[8] It is well camouflaged on its prey.[3] This species is able to quickly change colors as a response to unknown environmental cues.[3] ReferencesThis article incorporates Creative Commons (CC-BY-4.0) text from the reference[9] 1. ^Marcus Er.
