Aquatic Mammals

Seals eat fish. If sardines are where a seal could get them, they would- but would rather have larger fish.

a baby seal is called a pup

You may be confusing "heart" with "stomach." No mammal has more than one heart. Several animals have more than one stomach, or multi-chambered stomachs. These are called ruminants. a Ruminants are mammals in the order Artiodactyla. They predigest their food in the first stomach, regurgitate it, re-chew it (it is called cud now) and re-swallow it.

yes only some seals not all off them

two narwhals get in a fight until one rips the horn off the other and uses it to have butt sex with the other and then impregnating them

• yes,some do

it travels mostly by swimming.

Elephant Seals are found in Antarctica.

A leopard cub is born with its eyes closed and with faintly spotted smoky gray furs.Newborn leopards can open its eyes about seven to ten days after birth and can walk in about two weeks. For most of time during the first two to three months, baby leopards remain in hiding in the den especially when the mother leopard goes out hunting. The baby leopards start to eat meat when they are about six weeks old. Juvenile leopards can follow their mother on hunting trips when they are about two to three months old. Their mother's milk begins to reduce, and they are weaned when they are about three to four months old. They start to learn hunting and tree-climbing skills around this time. By the age of one, young leopards can hunt up to medium-sized animals independently. They start to leave their mother and find and establish their own home ranges when they are about 18 months old. Most of young leopards become fully independent by the age of two. A leopard is fully grown up and becomes an adult at around age three even though some female leopards start their first mating at two years old. Male leopards usually have their first chance to mate at about three or four because they face more competition from other males. Leopards live up to 15 years in the wild and 23 years in captivity. Leopards face many threats in the wild. The biggest threat to leopards comes from human beings. People kill leopards for various reasons. On the other hand, the habitat loss primarily caused by people also threats the survival of leopards in the wild.

A marmot looks very similar to a beaver. We recently visited Yosemite and saw an animal that at first glance resembled a beaver. Problem was it had a smaller and furrier tail. After returning home, with a picture of the critter, we looked at the Yosemite website for animals that lived in Yosemite and found the picture of the marmot.

Manatees do not have claws or sharp teeth, so if they are attacked by crocodiles, alligators, sharks and killer whales, they are in trouble. They do not travel in large herds so the others cannot help to warn or protect a manatee from attack. Their only real protection strategy is to remain in shallow water. This way, if they are attacked, it is less likely that the predator can drag them further under the water for longer than the 15 minutes that the manatee can survive without breathing.

Seals are aquatic mammals. There are about 32 species of seals. There are two types of seals: the earless, or true, seals (family Phocidae); and the eared seals (family Otariidae), which are sea lions and fur seals. In addition to the presence of external ears, eared seals have longer flippers than earless seals.

No.They eat a tiny sea creatures - krill or plankton. An Adult blue whale can eat up to 40 million creatures per day - that's nearly 3500 kilograms of it.. They need 1.5 million kilocalories of energy per day and so, they eat nonstop.

Seals burrow in the snow and go under the water for shelter. Have un research!

Just the opposite. Puffins eats fish. Adult puffins mostly eat small fish, such as sand eels, herring, hake and capelin. Puffin diets vary from colony to colony because of the variety of fish around the breeding islands. During winter puffins may also eat crustaceans, but their preferred food is fish. The young puffins are usually fed fish by their parents.

Sea elephants have no known land predators. However, great white sharks and killer whales prey on them in the oceans.
The elephant seal eats fish and squid, and is prey to the white shark and killer whale.

Certainly. Every living species can evolve. At some point seaweed evolved out of something, and other plants no doubt evolved out of seaweed-like ancestors.

However, no individual plant or animal can evolve in the sense of changing into a different plant or animal in the course of a single lifetime.

Sea lions generally breed between May and August when they arrive at their rookeries. The females in will mount the males. These groups begin to disintegrate as the females begin to mate. Sea lions have a 12-month reproductive cycle.

There are far, far too many too list, however, here are a few:

Trilobites: animals similar in appearance to the horseshoe crab, that lived from 526 to 250 million years ago.

Anomalocaridids: long and narrow, invertebrate carnivores that lived from about 500 to 400 million years ago.

Ammonites: invertebrates with a snail-like shell that protected a squid-like body, and floated in the ocean, who lived from 400 to 65.5 million years ago.

Icthyosaurs: marine reptiles that resembled dolphins, or fish, and lived from 245 to 90 million years ago.

Plesiosaurs: marine reptiles with long or short necks, who ate fish and swam with flippers, and lived from 210 to 65.5 million years ago.

Hesperornithes: Fully aquatic birds that lived from 100 to 65.5 million years ago.

Mosasaurs: Huge, carnivorous marine lizards (up to 40 feet long), that lived from 85 to 65 million years ago.

Enchodus (or saber toothed herring): a small to medium predatory fish with two long "fangs," that lived from the late Cretaceous to the Eocene (perhaps 100 to 40 million years ago).

Basilosaurus: a very long and narrow relative of whales, that lived from 40.4 to 33.9 million years ago.

Megalodon: a shark that may have been up to 50 feet long, and lived from 25 to 1.5 million years ago.

There are also a number of prehistoric ocean animals that still exist today, such as:

Sharks and rays: evolved about 416 million years ago.

Coelocanth: a type of fish related to lungfish that evolved about 400 million years ago.

Cephalopods (invertebrates such as squid and octopi): evolved about 400 million years ago.

Barnacles: evolved about 500 million years ago.

Coral (yes, they are animals): evolved about 542 million years ago, although modern coral reefs didn't first appear until about 245 million years ago.

sea gulls drink both sea water and also fresh water

There are several species of Sea Lion The smallest are the Galapagos Seal which weighs about 70kg The largest is the Stellar Sea Lion which can weigh up to 1000 kg
