The Aplocheiloidei are a subordinate group of the tooth fish (Cyprinodontiformes). The small freshwater fish are found in South America, Africa, India , Sri Lanka , Madagascar , the Seychelles and in Southeast Asia as far as Java .
features
The fish are slim to stocky, usually round in cross section, and are 2.2 to 22 centimeters long. As a rule, the males are brightly colored, the females monochrome gray or brownish. In contrast to cyprinodontoidei , whose ventral fin bases are far apart, the Aplocheiloidei are close together. A metapterygoid is present; the cyprinodontoidei lack this skull bone. Aplocheiloidei have three Basibranchialia (bones at the base of the gill arch), the Cyprinodontoidei two. The anterior nostrils of the aplocheiloidei are tubular. The lacrimal is narrow and twisted. The basihyale, an element between the hyoid bones, has a wide front end. The posterior extension of the vomer is dorsal (over) to the anterior arm of the parasphenoid . The mesethmoid, a skull bone, is cartilaginous.
Among the Aplocheiloidei to find the seasonal fish , also known as annuelle fish. This is understood to mean fish that regularly inhabit drying waters. The fish do not survive the drying up of their home waters, only the eggs survive in the mud. Due to the onset of rain at the end of the dry season, the juvenile fish hatch and then go through their life cycle in less than a year.
