Fish
Poecilia mexicana
Atlantic mollies (Poecilia mexicana) are widespread in freshwaters from the Rio san Fernando, Mexico, south to at least Honduras. Males (A) can become 7 cm, and because female growth does not stop after maturity, females (B) can become 9 cm in body length- While females have a cryptic coloration, males show a blue-orange colouring in the tail fin and the dorsal fin.
