Kanekonia is a genus of marine ray-finned fish, velvetfishes belonging to the family Aploactinidae. The genus is found in the western Pacific and eastern Indian oceans.
Taxonomy
[edit]Kanekonia was originally described as a genus in 1915 by the Japanese ichthyologist Shigeho Tanaka when he was describing the new species Kanekonia florida from Japan, its type species by monotypy.[1][2] The genus Kanekonia is classified within the family Aploactinidae in the suborder Scorpaenoidei within the order Scorpaeniformes,[3] although this family is also treated as a subfamily of the stonefish family Synanceiidae[4][5] within the Scorpaenoidei, which in turn is treated as a superfamily within the order Perciformes.[6] The name of the genus, Kanekonia honours Ichiro Kaneko, who supplied Tanaka with fishes from a fish market in Nagasaki, Japan, including the holotype of K. florida.[7]
Species
[edit]There are currently four recognized species in this genus:[8]
- Kanekonia florida S. Tanaka, 1915
- Kanekonia leichhardti J. W. Johnson, 2013 (Leichhardt's Velvetfish)[9]
- Kanekonia pelta Poss, 1982
- Kanekonia queenslandica Whitley, 1952 (Deep velvetfish)
Characteristics
[edit]Kanekonia velvetfishes are characterised by having a short, deep body with an extremely large head and mouth, with a protruding lower jaw. The preoperculum has 5 blunt spines. The scales take the form of outwardly directed spines, similar to tiny papillae with those on the back and flanks being the largest. They have a continuous dorsal fin which has its origin above the rear part of the eye The spiny part of this fin is longer than the soft-rayed part.[10] The dorsal fin has 11 to 13 spines and 7 to 10 sof rays, while the anal fin has a 1 or 2 spines and between 7 and 9 soft rays. The fin spines do not have venom glands.[9] These are small fishes, the largest species is the deep velvetfish (K. queenslandica) which reaches a maximum total length of 6.4 cm (2.5 in).[8]
Distribution and habitat
[edit]Kanekonia velvetfishes are found in the eastern Indian and western Pacific Oceans.[8] These fishes are demersal and are found mainly on sandy substrates.[11][12]
