Pectoral fins are also for mudskipper to jump.Mouth tongue Mudskipper has an unusual way to eat by sucking in its prey using ‘tongue’ made out of water eat and be eaten The foodchain The foodchain didyouknow?

Its also has aerial views which can see 360 degrees. When it is out of water, mudskippers retract their eyes beneath them to moisten them. It can also see above and below water simultaneously. 360 degrees. visiontype: monocromatic caudalfin anal fin Breathing O2 IN WATER ON LAND Breath using gills like most fishes 2 ways to breath on land: Gills chamber is filled with water which allows them to use gills to breath on land.

Male’s body colors will brighten It will do several jumps and flips Their dorsal fin will also spread Purpose:Purpose: to scare of rivals to impress females its mating season! After the female is found the male will make a burrow. The female will proceed to lay eggs in it if she likes the burrow. didyouknow? Mudskipper usually makes the burrow on mudflats which has hypoxic water. protection against prey. thermoregulation in which the mudskipper maintain their temperature.
