Which animals live in water
which animals live in water
- The hippopotamus is a mammal.
- After the elephant and rhinoceros, the hippopotamus is the third-largest type of land mammal and is the heaviest extant artiodactyl (in the traditional, non-cladistic sense of the term, excluding cetaceans).
- If they stay too long on dry land on a hot day, they quickly dehydrate.
- The hippo is among the most dangerous animals in the world due to its highly aggressive and unpredictable nature.
- Hippos have barrel-shaped bodies with short legs and long muzzles.
- Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.
- Some kinds of crocodile live in salt water and others live in fresh water.
- heir movement in the water is powered by their tail.
- However, they have many similarities in these areas as well. Many species are at the risk of extinction, some being classified as critically endangered.
3. sea otter
- Otters are part of the mammal family called mustelids, which includes ferrets, badgers, minks and weasels.
- The sea otter inhabits nearshore environments, where it dives to the sea floor to forage.
- For these reasons, the sea otter remains classified as an endangered species.
- The sea otter displays numerous adaptations to its marine environment.
- They are social, and play with each other, chasing or sliding down river banks or snow.
4. water snail
- Snails belong to a family of animals called molluscs.
- Freshwater snails are gastropod mollusks which live in fresh water.
- At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments.
- The biggest of all snails is an Australian sea snail that can grow to a length of over 77 cm and a weight of 18 kg.
- A seahorse (also written sea-horse and sea horse) is any of 46 species of small marine fish in the genus Hippocampus.
- They lack the caudal fin typical of fishes.
- They are unique in appearance, with their horselike head, prehensile tail, independently moving eyes, and brood pouch.
- Seahorses are rather immobile, swimming more slowly than other fishes.
- These plants provided seahorses with useful hiding places to avoid enemies and to capture unsuspecting prey, and ancestors of the seahorse evolved to maximize the opportunities offered by this new habitat.
- They live almost exclusively in the southern hemisphere: only one species, the Galápagos penguin, is found north of the Equator.
- They are about 71 – 76 cm tall and weigh about 4.5 kg and are the most numerous of penguins, with a population of about 12-13 million, found only on the Antarctic Peninsula and the sub-Antarctic islands.
- Although almost all penguin species are native to the southern hemisphere, they are not found only in areas with cold climates, such as Antarctica.
- Octopus, plural octopuses or octopi, in general, any eight-armed cephalopod (octopod) mollusk of the order Octopoda.
- Octopuses appear in mythology as sea monsters like the kraken of Norway and the akkorokamui of the ainu, and probably the gorgon of ancient Greece.
- The typical octopus has a saccular body: the head is only slightly demarcated from the body and has large, complex eyes and eight contractile arms.
- During osmoregulation, fluid is added to the pericardia of the branchial hearts.
8. sea snakes
- sea snake, any of more than 60 species of highly venomous marine snakes of the cobra family (Elapidae).
- All sea snakes have paddle-like tails and many have laterally compressed bodies that give them an eel-like appearance.
- Snakes generally avoid people and only strike when threatened.
- The only genus that has retained the enlarged ventral scales is the sea kraits, laticauda, with only five species.
- The platypus sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania.
- These animals build their holes at the very edge of the water and feed on underwater worms, mollusks and insects.
- When the first Platypus specimen arrived in Britain in 1798, it was thought to be a hoax as the Platypus looks like it is a mixture of a mammal and a bird.
