Despite the Amazon Deltadischargingmore than a billion tons ofsedimenta year, the delta does not have a subaerial expression and thus does not meet the classic definition of a regular delta.

It has a tropical climate with high humid temperatures. The Amazon Delta has a wet season of frequentfloodingand a dry season where thewaterdries out. These seasons shape the environment of the Amazon Delta and the life that lives there. Such life that lives in the Amazon Delta include the water buffalo which Marajo Island is well known for, three-toed sloths,capybara,giant anteater, giant otter,jaguarandpink river dolphins.[6]
