The climate of an estuary depends on its location. Some estuaries have four seasons, autumn, winter, spring and summer. But others have two seasons, a wet season and a dry season. It is mild & humid in an estuary. The average rainfall & temperature also depends on where the estuary is located.
long feet help it stay up in deeper water
antennae can sense vibrations, smell and taste chemicals in the water to help detect prey or predators
gills/lungs have developed over time so that they can breathe in moist air
