Fav Aquatic Creatures

Photoplankton are tiny free-floating photosynthetic plants that support the marine food web like trees and grasses on land.

Zooplankton are microscopic animals that eat other plankton. They range from single-cell organisms to tiny crustaceans.

Aquatic macrophyte are aquatic plants that are large enough to be apparent to the naked eye. They are larger than most algae.

Found in the Amazon region of South America, angelfish are laterally compressed or look like a disc on edge with long fins coming out of the top and bottom and have 2 feelers in front of the anal or bottom fin. The tail is vertically oriented and may be scoop shovel shape to long and relatively narrow depending on the variety.

Crustaceans form a very large group of arthropods, usually treated as a subphylum. The group includes familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. Most crustaceans are free-living aquatic animals, but some are terrestrial.

Mammals are any of the various warm-blooded vertebrate animals of the class Mammalia. This includes humans, characterized by a covering of hair on the skin and, in the female, milk-producing mammary glands for nourishing the young.
