They've only caught dead giant squids. Recently, a team of Japanese scientists filmed one, but it wasn't eating.\n\nSquids generally are carnivores. They will eat fish, sharks, etc. I suspect a giant squid eats the same, just lots more...

Moose\n\nThe MOOSE is the world's largest member of the deer family. Moose are generally associated with northern forests in North America, Europe, and Russia. In Europe they are called "elk". Moose are long-legged and heavy bodied with a drooping nose, a "bell" or dewlap under the chin, and a small tail. Their colour ranges from golden brown to almost black, depending on the season and the age of the animal. The hair of newborn calves is generally red-brown and they usually weigh around 28 to 35 pounds. Within five months the calves grow to over 300 pounds. Males in prime condition weigh from 1,200 to 1,600 pounds and adult female can weigh from 800 to 1,300 pounds. Only the bulls have antlers.  The largest moose antlers in North America come from Alaska, the Yukon Territory, and the Northwest Territories of Canada. In the wild, moose rarely live more than 16 years.    \n\n   Cow moose generally breed at 28 months and the calves are born any time from May to early June after a gestation period of about 230 days. Cows give birth to twins 15 to 75 percent of the time, and triplets may occur once in every 1,000 births.  The calves are weaned in the fall time when the mother is breeding again. The maternal bond is generally maintained until calves are 12 months old at which time the mother aggressively chases her offspring from the immediate area just before she gives birth.  Moose breed in the fall with the peak of the "rut' activities coming in late September and early October. Adult males joust during the rut by bringing their antlers together and pushing. Serious battles are rare although a few occasionally die from their wounds. The winner usually mates with the female.\n\n    During the fall and winter, moose consume large quantities of willow, birch, and aspen twigs. Spring is the time of grazing as well as browsing. Moose eat a variety of foods, particularly sedges, horsetail, pond weeds, and grasses. During the summer, moose feed on vegetation in shallow ponds, forbs, and the leaves of birch, willow, and aspen.\n\n   Moose are killed by wolves and black and brown bears. Black bears take moose calves in May and June and brown bears kill calves and adults the entire time the bears are out of their winter dens. Wolves kill moose throughout the entire year. Moose are also a very popular animal for people to hunt, which is another way that limits the growth of the moose population.\n\nMan's removal of mature timber through logging and careless use of fire has, in general, benefited moose as new stands of young timber have created vast areas of high-quality moose food. The future for moose is reasonably bright because man is learning how to manipulate habitat with wildfire and is becoming more skilled at managing factors that limit moose populations, such as predation and hunting. \n\nCaribou\n\nThe CARIBOU live in the artic tundra, mountain tundra, and northern forests of North America, Russia, and Scandinavia. The world population is only about 5 million. In Europe caribou are called reindeer, but in Alaska and Canada only the domestic forms are called reindeer. All caribou and reindeer throughout the world are considered to be the same species, but there are 7 subspecies: Barrenground, Svalbard, European, Finnish forest reindeer, Greenland, Woodland, and Peary. Alaska has only the barren-ground subspecies, but in Canada the barren-ground, Woodland, and Peary subspecies are found. The caribou found on the Slate Islands in Terrace Bay, are Woodland caribou.\n\n    Caribou have large, concave hoofs that spread widely to support the animal in snow and soft tundra. The feet also function as paddles when caribou swim. Caribou are the only member of the deer family in which both sexes grow antlers. Antlers of adult bulls are large and massive; those of adult cows are much shorter and are usually more slender and irregular. In late fall , caribou are clove-brown with a white neck, rump, and feet

Well, a grouse is a prey animal. If there was a decline in the population of grouse, then the animals that usually prey on the grouse - coyotes, owls, etc - would probably start eating other prey animals, like the pheasants and squirrels.

Fish eat other fish. Bigger ones eat smaller ones. In the case of a whale, notice its strainer type mouth? They take in large quantities of Crill which are very small shrimp. Others feed by sucking plankton or moss off rocks (thus cleaning). Others by snatching flying or swimming bugs off the surface.

the mink...  it is likely due to the fact that they have short, active lifespans... they need a constant, high energy diet but can not eat too much in one sitting..  during evolution, it's likely that there was little to no energy invested in development of the digestive tract because of its short lifespan...\n\nalso, being a carnivore, they have no need for a cecum and long digestive tract (like rabbits, sheep, and deer) which is useful in extracting the low amounts of energy from plant material...

They live in the forest or in suburbs.  They nest in tree cavities, old logs, etc.  They are omnivores, meaning they eat a variety of plant and animal life.  Birds, frogs, insects, vegetables, fruits.

Yes, they do swallow their food.  Perhaps you meant chew. In which case, no they do not chew. Instead they rip of chunks small enough to swallow and then swallow.

Depends what kind of animals! Some eat other animals.  Some forage under the snow for food.  Some eat tree bark, etc.  Some get fed by humans.

some birds eat bugs, etc, while some eat grains or fruit.  Suet would appeal to the meat or insect eating birds.

usually, they eat each other. Have you ever heard that "the big fish eats the small one"? Also, they can eat plancton, or algae... there are plenty of food (organic material) floating around in the ocean.

Diet is reconstructed by reconstructing the animal and reconstructing its environment.\n\nReconstructing the environment can be achieved by looking at the plant fossils that occur alongside an animal. That gives a good indication what type of habitat the animal lived in, whether it was tropical rainforest, arctic tundra, desert etc. With that information it is possible to construct a list of possible diets. For example we won’t speculate that an animal could have eaten bamboo if it live din deserts, and we can rule out that an animal ate lizards if it lived in polar wastes.\n\nThe next step is to reconstruct the animal itself. \n\nThat reconstruction normally starts with the teeth. Teeth can tell us a lot about diet. For instance predatory animals usually have sharp widely-spaced teeth like a lion or crocodile, while herbivores have rounded, closely packed teeth like a cow.  \n\nThe next step is to look at teeth wear. Looking at teeth structure gives us a lot of information about diet but it isn’t perfect since animals like pandas and fruit bats have sharp carnivore type teeth yet live entirely on plants. But plant leaves contain a lot of hard material and they wear teeth away very fast and leave a lot of scratches, so we can see whether an animal ate a lot of plant material by looking at the teeth. That way we can tell separate out animals like pandas and fruit bats that recently evolved a vegetarian diet from their carnivorous descendants.\n\nThe next step is to reconstruct the rest of the skeleton. By looking at the ways the bones are hinged and how big the muscle attachment points were we can get a very good idea of how an animal moved. That then tells us thing like whether a meat eating animal was strong and fast enough to make its own kills like an eagle, or whether it had to rely on scavenging like a vulture. It also tells us whether an animal could climb, or swim or burrow.\n\nThe final step is to look at injuries. When bones break they leave a scar even after hey heal, and starvation and disease also leave marks on bones. By looking for those signs we can see whether the animal was suffering from injuries associated with being kicked by prey animals, or from falls from trees and so forth and we can tel whether its prey was seasonally abundant like salmon, or whether it was available year-round like tropical grasses.\n\nSo now we know what types of food existed alongside the animal because we reconstructed its habitat.\nAnd we know what the animal was adapted to eat by the tooth structure.\nAnd we know how much plant material it ate from the wear on the teeth.\nAnd we know whether the animal got that food by hunting, scavenging, swimming, climbing etc. from the muscle and bone structure.\nAnd we know when that food was available, what sort f animals were being attacked by predators and so forth.\n\nWith all that information we can build up a very accurate picture of animal diets just form fossil evidence.

Polar bears, IN THEIR NATURAL ENVIRONMENT, don't eat penguins because they live at opposite ends of the globe (And, hence, never encounter one another).  HOWEVER, it has been discovered (accidentally (One would hope)) that polar bears WILL eat penguins, if given the opportunity in the zoo.

"Mink lack a cecum and have a very short intestinal tract (4x body length) with a small stomach. Consequences of these features are the need for frequent food intake in small amounts (nine to 10 meals daily in the wild) and a rapid rate of food assimilation. The average daily intake is 40-53 g with a transit time of approximately three hours."\n\nthe girl below me is dumb because minks, seals, and cougars are ALL carnivores....\n\nminks like ferrets lack a cecum and have a short digestive tract... as I've already said...

They are eaten. If not by carnivores then by bacteria, fungi, and invertabrates. Think "circle of life" from the lion king.Then they go to that big perch in the sky.

Amphibians are hunters; they eat anything from insects to birds and small mammals, reptiles, and other amphibians.  Frogs, for instance, huntby sight, and will go after anythign that moves in their path that is is a relative size to the prey they hunt (ie. flies, bugs).
