The red velvet fish ( Gnathanacanthus goetzeei ) is a fish from the order of the perch-like (Perciformes). He was placed in his own, thus monotypical family. The red velvet fish is endemic to the seabed on the southwest and south coast of Australia and in northern Tasmania in rocky reefs and in algae and seaweed fields.
features
Red velvet fish grow to be 30 centimeters long. You are scaly. The body is smooth or covered with tubercles and papillae. Of the two almost equally long, high dorsal fins, the first is supported by seven hard rays, the second by three hard and ten to eleven soft rays. The anal fin has three hard and eight to nine soft rays, the pelvic fins one hard and five soft rays, the pectoral fins ten to twelve fin rays . All fin rays are undivided. The hard rays can cause painful wounds. There are two large spines on the gill cover that can be hidden under the skin. The number of vertebrae is 28 to 30. Red velvet fish are bright red in color or are brown with red stripes.
The red velvet fish is closely related to the stone fish (Synanceiidae). A characteristic that it shares with the stone fish is a saber-shaped, defensive outgrowth of the lacrimale , the tear- saber . Smith, Everman and Richardson therefore propose that the family Gnathanacanthidae be downgraded and assigned to the stone fish as a subfamily.
