Anableps tetrophthalmus (originaly Cobitis anableps Linnaeus 1758, Scopolis 1777; Michel et al. 2015; 32 cm) is the extant four-eyed fish (aka: cuatro ojos), a surface predator of insects falling into Amazonian fresh waters or shallow shores where Anableps beach themselves to eat them. The underslung jaw enables this behavior.
Traditionally and here Anableps is a member of the pupfish (guppy, killifish, topminnow) family. Internal fertilization (with a modified tubular anal fin) leads to live birth (viviparity) of up to 14 young. |
