Mud-skipper

Breve definicion: Los Periophthalmus, peces del fango pertenecen a la clase de los Osteictios; subclase: Neopterigios; orden: Perciformes; familia: Gobidios; especies zoológicas de pez capaces de vivir al aire libre, nutriéndose de insectos y de pequeños invertebrados.

El género Periophtalmus (saltador del atlántico) vive en aguas de los manglares; haciendo lo que otros no pueden: respirar aire en un modo de vida anfibio.[1] Se los encuentra en regiones tropicales y subtropicales, incluyendo todo el Indo-Pacífico y el Atlántico con las costas de África. Son sumamente activos fuera del agua, pero siempre necesitados de fango, alimentándose e interactuando con el entorno, por ejemplo para defender su territorio.

Cosas que pueden hacer (en ingles):

Do they walk? Mudskippers have arm-like pectoral fins which even have little "elbows". But they do not move these alternately in the way that we walk. Instead they make little hops by keeping their body rigid and jerking forwards on their pectoral fins; called "crutching" because the movement is similar to that of a person on crutches. They leave typical trails on the mud (right).

on a tree branchHow do they climb? Some mudskippers have specially adapted pelvic fins which act like suckers to hold them agains a vertical surface, while they use their arm-like pectoral fins to "reach" up and "pull" themselves up. In this way, they can creep up roots and rocks.

How do they skip? By flipping their muscular bodies, they catapult themselves for a distance of up to 60cm. They skim over mud as well as the water surface. Mudskippers actually move faster on land and on the water surface than by swimming with their bodies in water.
