aquatic animals classification

The various aquatic habitats of the world support a diverse assortment of wildlife including virtually many different groups of animals including fishes, invertebrates, amphibians, mammals, reptiles, and birds. Invertebrates (Animal without backbone) Some animals have no backbones. Types of aquatic animals include marine mammals such as whales, dolphins, sea lions, seals, manatees and walruses. Mammals Facts. Animal Classification In order for us to understand how all living organisms are related, they are arranged into different groups.The more features that a group of animals share, the more specific the group is.

Mammals are warm-blooded animals. Marine Animals: About three fourths of the earth’s surface is covered by the oceans. They are sedentary and can exist in colonies or lead solitary lives in coastal marine environments. They use their skin as a second respiratory system. The animals which live in water are called aquatic animals. Fish, frog, bird, lizard, snake, tiger, rabbit, whale, man, etc. The salt water serves as the home for the marine animals who can survive neither in fresh water nor on land. Aquatic Invasive species - Regulated animals Whether they come in ballast water, on the hulls of recreation boats or from the water of an angler’s bait bucket, many non-native species such as zebra mussels and Eurasian water milfoil have found their way into Wisconsin’s waterways. Nekton are aquatic animals that can move on their own by “swimming” through the water.
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). Environment: Amphibians live in wet Phylum Gnathostomulida . The land animals, Defined by zoology, are those that comprise those who inhabit the earth. According to the nature of the water aquatic animals may be marine or fresh-water. The term “entoprocta” refers to internal anus. Examples of nekton include fish and shrimp. Only two mammals hatch from eggs. They feed on plankton or other nekton. Amphibian, any of roughly 8,100 vertebrate species known by their ability to exploit both aquatic and terrestrial habitats. List of animal phyla is a list of the major groups of animals usually classified as a phylum. Mammals drink milk from their mothers. ... another phylum of small aquatic animals, with about 700 species. Vertebrates (Animals with backbone) Some animals have backbone called vertebral column and a hard skeleton of a number of bones. Bats are the only mammals that can fly. They also have gills and lungs. Dolphin and whale babies do not sleep the first month of their life. Your body is ready to crawl, walk, run, climb or jump, depending on the ecosystem in which they live. Mammals are born live. These are sessile goblet-shaped aquatic animals known as goblet worms. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. Unlike aquatic, aerial or air-terrestrial animals, terrestrial animals spend most of their time and fulfill most of their biological processes and vital functions in the terrestrial soil. Invertebrate aquatic animals include sponges, corals, sea stars, sea anemones, sea urchins and sea cucumbers. Other types are fish, including bony fish such as groupers and cartilaginous fish such as sharks and rays. The backbone is a part of the skeleton. Some groups—such as echinoderms, cnidarians, and fishes—are entirely aquatic, with no terrestrial members of these groups. They may live in the photic or aphotic zone. Animals are given scientific names so that people all around the world can communicate about animals, no matter what language they speak (these names are traditionally Latin words).

They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes.

Benthos are aquatic organisms that crawl in sediments at the bottom of a body of water.

The name amphibian, derived from the Greek word meaning ‘living a double life,’ reflects this dual life strategy, but some species are permanent land dwellers, and others are completely aquatic. About 4445 extant mammals (Pough et al., 1996) have been recorded from the diffe­rent parts of the world of which 500 species are known from the Indian region (Prater, 1980). Their skin is soft and glandular. Simpson’s (1945) classification on mammals recognised 18 living orders, of which 12 are represented from the Indian region. Many are decomposers. 1. Classification based on traditional comparative anatomy had errors which needed to be corrected. Aquatic Animals Classification Protists & Fungi Agnatha Amphibia Characteristics: Amphibians begin as larvae in water. This is a relatively new phylum of around 100 microscopic marine animals known as ciliated jaw worms. This classification is designed to cover the products derived from fish, crustaceans, molluscs, other aquatic animals and plants for which the Food and Agriculture Organization of the United Nations (FAO) collects national statistics on production and trade on a regular basis.
