Diagnostic Description

provided by EOL authors
Species of Periophthalmus are as yet undefined by a synapomorphy. However, they are characterized by the following features (which may or may not be shared with non-congeners): possession of compressed, convex posterior extensions on the neural and hemal spines of caudal vertebrae 8-13; pelvic fins only partially united or totally separate; and in possessing 16 or fewer (typically 12-14) pectoral-fin rays. Additionally, species of Periophthalmus live in association with both the mangal and mudflat ecosystems, and are the most amphibious of any oxudercine.

Periophthalmus

provided by wikipedia EN

Periophthalmus is a genus of fish in the family Oxudercidae, native to coastal mangrove wood and shrubland in the Indo-Pacific region, except for P. barbarus from the Atlantic coast of Africa. It is one of the genera commonly known as mudskippers. Periophthalmus fishes are remarkable for being able to live, temporarily, in open air where they feed with insects and small invertebrates; out of water they have limited motion abilities, such as jumping. All Periophthalmus species are aggressive and territorial.[1]

Species

There are currently 19 recognized species in this genus[1]
