The brick winged steed ( Pegasus laternarius ) is a small fish from the group of pipefish-like fish found in the Indian Ocean ( Gulf of Mannar ) and in the tropical, western Pacific from the Gulf of Thailand over the South China Sea along the coast of southern China, around Taiwan and north to Suruga Bay on the Pacific coast of the island of Honshū in Japan . The fish live on muddy bottoms, the larvae are planktonic. They are relatively rare, most common at depths of around 50 meters. A few protected, muddy regions are known from Japan, in which they live between 30 and 100 meters water depth.

features

The brick winged steed becomes eight centimeters long. Its color is variable and it can be dull to bright yellow or blue. The underside is always lighter. The rostrum is very short in juveniles and females, longer in males. The top of the head is without deep pits. The edge of the eye sockets is flaky. When viewed from below, the eyes are covered by the lower edge of the eye sockets. The body is oval and clearly separated from the long tail fin stalk. It is armored by four pairs of dorsolateral (on the sides of the back) and five pairs of ventrolateral (on the sides of the abdomen) bone plates. The only dorsal fin sits on the caudal fin stalk and, like the anal fin , is supported by five soft fin rays. The caudal fin stalk is surrounded by eleven or more bony rings, the first of which are movable against each other, while the ninth and tenth have grown together. The last bone ring of the tail fin stalk has no spine on the dorsal side. The pectoral fins are fan-shaped, the fifth fin ray much thicker than the other rays. The distal edge of the dorsal and anal fins is inclined to the horizontal axis of the body. The number of vortices is 20.
