What does «aleta pectoral o torácica» mean in Spanish?
- Each of the two fins immediately behind the head. Also called scapular or thoracic fin. They serve for slow locomotion, turning and braking; they also serve certain fishes for depth maintenance, flying in flying fishes or walking such as Lophiiformes and those of the subfamily Oxudercinae. The pectoral fins are homologous to the forelimbs of tetrapods. In fact, in some fishes, the rays of the pectoral fins extend similar to fingers as in Scorpaeniformes and Dactylopteridae.
