The most important feature

(percentage of salt content in water)
Brackish water is
essential
for mudskippers to live
This particular lake is

4. Body PartsBody Parts
how mudskipper carries their everyday function

Dorsal Fins are generally closed but it will
open if the mudskipper is being aggressive
or if it want to impress the female during
mating season.
Pectoral Fins
walk

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.
Breath through the skin if its moist and wet.
how do mudskippers adapt to its environment?
Amphibiouslifestyle
Allows mudskipper to:
Survive during lowtide
Survive in low oxygen waterOxygen
Find its prey on land delicious
