Felimare gasconi (Ortea in Ortea, Valdés & García-Gómez, 1996)
Felimare gasconi (Ortea, 1996)
|Classification according to Bouchet et al. (2017)|
Taxonomic source: World Register of Marine Species (AphiaID: 597822).
Taxonomic note: The European Atlantic and Mediterranean species of the genus Chromodoris and Hypselodoris have been reconsidered. After molecular analysis of the Chromodorididae performed by Johnson & Gosliner (2012, Traditional taxonomic groupings mask evolutionary history: A molecular phylogeny and new classification of the chromodorid nudibranchs. PLoS ONE 7(4): 33479) the Hypselodoris species have been included in the genus Felimare Ev. Marcus & Er. Marcus, 1967 and the Chromodoris species have been included in the genus Felimida Ev. Marcus, 1971.Synonyms
- Hypselodoris gasconi Ortea, 1996
Animal with dark blue body, with a line that runs along the notum edge, coloured yellow-orange on the sides and white on the front and back of the mantle. It has three dorsal white lines parallel to each other, the middle line can be continuous or fragmented, and is thicker than the lateral lines, which can also be continuous or fragmented, or even may not be straight or not even present. The middle line surrounds the gill and continues a little further towards the back. The sides are crossed by a very thin white line that passes under the genital opening, without surrounding it. This species is characterized by having defensive structures called Mantle Dermal Formations (MDF); these are placed next to the rhinophores (between 1 and 5, usually 2-3) and behind the gill (up to 11, usually 5-7). The tail has a triangular shape, protrudes from the back of the dorsum and has a white line along the middle dorsal side. The rhinophores are blue, with the upper end of the rachis stained in white and have about six blue lamellae.
Food source for this species is unknown, although the other species of the genus feed on sponges and probably this species does so as well. The analysis of the defensive substances of the MDF (presence of longifoline) suggests that it feeds on sponges of the genus Dysidea (Ávila, 1993). The variable design pattern of the dorsal lines creates confusion with other species of the genus, but they can be told appart because Felimare gasconi has the edge of the mantle coloured intense orange and lacks the fine light blue lines between the lateral white lines and the border of the mantle that appear in the juveniles of Felimare fontandraui. Also the large amount of MDFs present in the back of the mantle is a characteristic trait.
- Gasconi. In honor to Dr. Santiago Gascón Muñoz (1939-1996), who was Rector of the University of Oviedo between 1992 and 1996.
This species has only been reported in the Western basin of the Mediterranean Sea and in the Adriatic Sea.
