The term aquatic refers to
water and can be either a noun or an adjective. Dictionary definitions do not specify what kind of water, although in both general use and in the sciences, the implication is often that of fresh water. The term
marine (ocean) is typically substituted where reference to salt water is intended, and
estuarine for brackish water (i.e., a mix of fresh and
salt water). On occasion, aquatic may refer to any or all of these three.
