Wildlife on the Pacific coast of the United States is home to many different families of animals, such as birds, mammals, fish, reptiles, amphibians, and invertebrates, both terrestrial and aquatic. In the San Francisco Bay Area network of national parks alone, there are over 250 species of birds. [ 4 ]
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
A History of British Fishes is a natural history book by William Yarrell, serialised in nineteen parts from 1835, and then published bound in two volumes in 1836. It is a handbook or field guide systematically describing every type of fish found in the British Isles, with an article for each species.
The term "fish" describes any non-tetrapod chordate, (i.e., an animal with a backbone), that has gills throughout life and has limbs, if any, in the shape of fins. [8] Unlike groupings such as birds or mammals, fish are paraphyletic, since the tetrapod clade is within the clade of lobe-finned fishes. [9] [10]
A lion (Panthera leo).Lions are an example of charismatic megafauna, a group of wildlife species that are especially popular in human culture.. Wildlife refers to undomesticated animals and uncultivated plant species which can exist in their natural habitat, but has come to include all organisms that grow or live wild in an area without being introduced by humans.

A wild fishery is a natural body of water with a sizeable free-ranging fish or other aquatic animal (crustaceans and molluscs) population that can be harvested for its commercial value. Wild fisheries can be marine ( saltwater ) or lacustrine / riverine ( freshwater ), and rely heavily on the carrying capacity of the local aquatic ecosystem .
Guppies have many predators, such as larger fish and birds, in their native range. Some of their common predators in the wild are Crenicichla alta, Anablepsoides hartii, and Aequidens pulcher. [35] Guppies' small bodies and the bright coloration of males make them easy prey, and like many fish, they often school together to avoid predation.
The more shallow the water, the greater the biomass contribution from rooted and floating vascular plants. These two sources combine to produce the extraordinary production of estuaries and wetlands, as this autotrophic biomass is converted into fish, birds, amphibians and other aquatic species.
