Origin of elasmobranchFrom New Latin Elasmobranchiī subclass name Greek elasmos metal beaten out ( from elaunein elas- to beat )Latin branchia gill ; see branchia .
Any of numerous cartilaginous fishes of the subclass Elasmobranchii, having five to seven gill slits on each side, dermal denticles for scales, and a small respiratory opening (spiracle) behind each eye. The pectoral fins of elasmobranchs are often greatly enlarged. Elasmobranchs include the sharks, rays, and skates.
- Almost exclusively parasitic in the intestine of Elasmobranch fish.
- The adults occur in Elasmobranch fish, the metacestode encysted in Teleosts.
- The Cestodes of Elasmobranch fish offer more convincing examples of independent growth of the proglottides, for these are often set free with only the male organs developed, and each attains twice the size of the parental strobila.
