Aporodoris millegrana is a species of sea slug, a dorid nudibranch, shell-less marine gastropod mollusk in the family Discodorididae. [7] [8]
This species was originally discovered and described (under the name Doris millegrana) by Joshua Alder and Albany Hancock in 1854. [1] Hermann von Ihering (1886) [9] designated Doris millegrana Alder & Hancock, 1854 as a type species of the newly created genus Aporodoris Ihering, 1886. [3] Charles Eliot (1910) [10] provisionally used the name Aporodoris millegrana but he expressed doubts about validity of the genus Aporodoris and he has thought that Aporodoris could be synonymous with genus Thordisa Bergh, 1877. [3] [10] Thompson & Brown (1981) [11] assigned this species to the genus Discodoris Bergh, 1877. [11] Valdés & Gosliner (2001) [3] synonymized genus Aporodoris with the genus Taringa Er. Marcus, 1955 because they (erroneously) considered the generic name Aporodoris unused since 1886 and they gave the precedence to widely used generic name Taringa. [3] Valdés & Gosliner (2001) [3] made an erroneous reversal precedence and International Commission on Zoological Nomenclature should publish a decision of what name should be used in such cases according to the Article 23.10 of the International Code of Zoological Nomenclature. In the meantime the name in prevailing usage must be used (according to the Article 23.10).
Dayrat (2010) [4] agreed with synonymization of the genera Aporodoris and Taringa. [4] But he considered the generic name Aporodoris and the specific name Aporodoris millegrana as valid [4] with strict application of the Principle of Priority.
This species occurs in European waters: British Isles, France, Tenerife, Spain, Mediterranean Sea. [2] [4] [12]
Alder & Hancock (1854) mentioned the locality Torbay, England in their paper [1] [2] but the type locality should be Torquay according to the name on labels of type material. [4]
Alder and Hancock have described the new species according to preserved specimens. [1] Alder's and Hancock's original text (the type description) reads as follows: [1]
Doris millegrana Yellow or orange?: cloak covered with minute granular tubercles: oral tentacles linear: branchial plumes 6, bipinnate, retractile within a cavity. Length 1¼ inch.
The length of preserved specimens of type material varies from 15 mm to 28 mm. [3] The color of live specimen is brown-orange or dark violet-brown. [3] The color of preserved specimens is yellow. [3] There are light violet-brown rhinophores with yellowish white apex on the head. [3] There are 120 μm long caryophyllidia covering the whole dorsal part of the body. [3] There are also 80 μm long tubercules on the body. [3]
Sea lemon is a loosely applied common name for a group of medium-sized to large shell-less colorful sea slugs or nudibranchs, specifically dorid nudibranchs in the taxonomic family Dorididae and other closely related families. These are marine gastropod mollusks.
Doridoidea, commonly known as dorid nudibranchs, are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia.
Chromodorididae, or chromodorids, are a taxonomic family of colourful, sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size.
Aldisa is a genus of sea slugs, dorid nudibranchs, marine gastropod molluscs in the family Cadlinidae.
Chromodoris is a genus of very colourful sea slugs or dorid nudibranchs, marine gastropod molluscs, and the type genus of the family Chromodorididae. Within the genus Chromodoris, there are currently 101 classified species. Species within Chromodoris are commonly found in tropical and subtropical waters, living as members of reef communities and preying primarily on sponges. A molecular phylogeny of the family Chromodorididae resulted in this genus being restricted to a smaller number of species than formerly, most of which have longitudinal black lines on the mantle. Many former members of Chromodoris were transferred to Goniobranchus
Okenia is a genus of colorful sea slugs, specifically of dorid nudibranchs, marine gastropod mollusks in the family Goniodorididae.
Acanthodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Onchidorididae. The genus is believed to have originated in the Atlantic Ocean in the Cretaceous period and spread to the Pacific Ocean. The relationships of Acanthodoris to the other genera in the family Onchidorididae were evaluated by molecular phylogeny in 2015.
Doris is a genus of sea slugs, specifically dorid nudibranchs. These animals are marine gastropod molluscs in the family Dorididae.
Atagema is a genus of sea slugs, specifically dorid nudibranchs. They are marine gastropod molluscs in the family Discodorididae.
Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.
Acanthodoris planca is a species of dorid nudibranch. It is a marine gastropod mollusc in the family Onchidorididae.
Taringa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Discodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
Diaulula is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
Paradoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Platydoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae. These nudibranchs are large and often brightly coloured, but normally live concealed beneath rocks or loose coral, feeding on sponges. During the night they become more active, searching for new food sources or mates. Many species were described in the 19th century and a revision in 2002 added six new species.
Thordisa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Montereina is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Aporodoris is a genus of sea slugs, dorid nudibranch, shell-less marine gastropod molluscs in the family Discorididae.
