- Simple put, a marine mammal is a mammal who lives in a marine or, in some cases, an aquatic environment and obtains all or most of its food there too.So, what is a mammal then? To be classified as a mammal an animal must posses all five of these characteristics. They have lungs and breath air.ll marine mammals were originally land mammals and share common ancestry and characteristics with every other mammal. Over time they became more and more specialized to meet the challenges of life in an aquatic environment.

Mammals Mammals. A mammal is an animal that feeds its babies with milk when it is young. There are over 4,500 types of mammals. Many of the most popular animals we know are mammals, for example, dogs, cats, horses, cows, but exotic animals like kangaroos, giraffes, elephants and anteaters belong to this group, too. mammal is an animal that feeds its babies with milk when it is young.

Marine Mammal Protection Act Marine Mammal Protection Act. The Marine Mammal Protection Act of 1972, Amended 1994. The U.S. Marine Mammal Protection Act (MMPA) protects all marine mammals, including cetaceans (whales, dolphins, and porpoises), pinnipeds (seals and sea lions), sirenians (manatees and dugongs), sea otters, and polar bears within the waters of the United States.

- The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). At up to 29.9 metres (98 ft) in length and with a maximum recorded weight of 173 tonnes (190 short tons) and probably reaching over 181 tonnes (200 short tons), it is the largest animal known to have ever existed.

The class includes the whales, carnivores, rodents, bats, primates, etc.ny warm-blooded vertebrate of the class Mammalia, characterized by a covering of hair on some or most of the body, a four-chambered heart, and nourishment of the newborn with milk from maternal mammary glands.

Why are whales mammals? Whales, dolphins, porpoises, seals, walruses, and many other marine animals are mammals, not fish. The marine mammals exist because about 50 to 60 millions of years ago, some mammals wandered off of the land and into the ocean, and there they evolved into different types of marine mammals.hales are mammals because they share the characteristics of other mammals (like us!). These characteristics include being able to regulate their own body temperature (unlike cold-blooded animals, like lizards), growing hair and producing milk to feed their young (who are born live, not in eggs).

Marine Animals Marine animals include: fish, mammals, reptiles, invertebrates and seabirds. Size: Marine animals cover the gamut from the microscopic zooplanktons to the world's largest whales. Habitat: The worlds oceans cover two thirds of our planet and the marine biome the largest, as well as most diverse biome in the world.

- For other uses, see Dolphin (disambiguation). Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic.

Marine Biology Marine biology is the study of marine organisms, their behaviors and their interactions with the environment. Because there are so many topics one could study within the field, many researchers select a particular interest and specialize in it.

Learn about Mammals What are mammals? Mammals are similar to reptiles and amphibians in the sense that they are also vertebrates. However, the females of mammalian species all develop mammary glands whereas the females of reptiles and amphibians do not. The mammary glands secrete milk, which provides nourishment to newborn or young mammals.

Marine Mammals: Phylum Chordata Marine Mammals: Phylum Chordata. The Pollack Farm Site, in the Cheswold sands of the lower Miocene Calvert Formation, produced a fragmentary marine mammal fauna. The Pollack location yielded at least six cetaceans (whales, porpoises), a sirenian(manatee), along with one of the earliest records of a true seal (Listed below). Marine mammals have the same characteristics as all other mammals, but they have adapted or adjusted to life in the ocean. For instance, many species residing in the deep oceans have a thick layer of blubber, which holds their body temperature warm.

Description & Behavior PHYSICAL DESCRIPTION. The blue whale is the largest mammal, possibly the largest animal, to ever inhabit the earth. Its body is long, somewhat tapered, and streamlined, with the head making up less than one-fourth of its total body length.

Anatomy Mammals are a class of animals belonging to the Phylum Chordata and Subphylum Vertebrata. They are defined by certain characteristics which all mammals share, including: gland…s that produce milk, hair, three bones in the middle ear, and a neocortex in the brain. Most mammals are born live, but there are exceptions.

THE FIVE VERTEBRATE GROUPS Most mammals are viviparous. This means that the offspring are kept inside the female's body and feed through a placenta. The largest mammal lives in the sea. It is the blue whale, which can reach 33,6 metres in length and has a mass of 190 tonnes. The smallest mammal is called the bumble bee bat.

What Is Marine Biology? First, it's important to understand what, exactly, makes up the marine biology branch of science. Marine biology is the scientific study of plants and animals that live in salt water. When many people think about a marine biologist, they picture a dolphin trainer. But marine biology is so much more than making a dolphin -- or sea lion -- follow commands. With the oceans covering over 70 percent of the Earth’s surface and providing habitat for thousands of species, marine biology is a very broad field.

- The largest mammal in the world is the Blue Whale. Once found in oceans and seas around the world, it is now found only in parts of the Antarctic Ocean, Atlantic Ocean, Indian… Ocean and the Pacific Ocean, having been hunted virtually to extinction.

What Is a Marine Biologist? Definition: Marine biology is the scientific study of organisms that live in salt water. So, a marine biologist is a person that studies, or works with a salt water organism (or organisms). That is a fairly brief definition for a very general term, as marine biology encompasses many things. Marine biologists may work for private businesses, in a non-profit organization, or at a university or college.

Marine life Marine biology. Marine biology is the scientific study of organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean.

- Mammals are warm-blooded vertebrates which, with the exception of a few notable species, nurse their young on milk produced by the female’s mammary glands, give birth to live young, and have bodies insulated by hair. Around one in four of the world’s mammals are currently threatened with extinction.
