Marine life, sea life or ocean life, is represented by the plants, animals and other organisms that live in the saltwater of the sea or ocean, or the brackish water of coastal estuaries.
At a fundamental level, marine life affects the nature of the planet. Marine organisms produce oxygen and sequester carbon.
Fish are limbless cold-blooded vertebrate animal with gills and fins living wholly in water.
Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families.
Rays look like bats in the water, and this is probably why they are called batoids. Rays use their pectoral fins to 'fly' through the water. Though a bony fish takes in water with its mouth, rays do not because they live at the bottom of the ocean.
Name a few of the most known species.

Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence.
They include animals such as seals, whales, manatees, sea otters, and polar bears. They are an informal group, unified only by their reliance on marine environments for feeding.
Seabirds are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behavior, and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations.
Name a few of bird species who live at sea or at the seaside:
