Wagner , 1828

The Cyprinodontoidei are a subordinate of the Zahnkarpflinge (Cyprinodontiformes). The small fresh and brackish water fish are found in south, central and eastern North America, on the islands of the Caribbean , along the Mediterranean coasts , in Turkey and in Africa.

features

The fish are slim to stocky, usually round in cross section, and are 2.5 to 32 centimeters long. In contrast to the tooth carrot suborder Aplocheiloidei , whose ventral fin bases are close together, they are far apart in the Cyprinodontoidei. A metapterygoid is missing; the cyprinodontoidei have this skull bone. The Cyprinodontoidei have two Basibranchiale (bones at the base of the gill arch), the Aplocheiloidei three. The upper (dorsal) hypohyal, a bone of the Branchiostegal apparatus , is missing. The meniscus between the premaxillary and maxillary is absent. The lower jaw is robust and broadened in the middle. A forward extension of the autopalatine, a pair of bones in the roof of the fish, is kinked and hammer-shaped. The ligament that normally runs from the interior of the maxillary to the center of the cartilage facing the snout is missing.
