Asked in Animal Behavior, Dolphins and Porpoises
What adaptations does the dolphin have?
Dolphins have adapted to their environment in the following ways: Fin shape: a dolphin's tail goes up and down to help it dive up to get air (compared to a fish's back fin which moves side to side). The shape of their fins also helps to propel them through the water. To help dolphins save oxygen while they dive underwater, their heart beats slower during a dive and their blood is diverted from other parts of the body to their heart, lungs, and brain. Dolphins also save oxygen via their muscles, which have a protein called myoglobin, which in turn stores oxygen. Dolphins have blubber, or fat, which provides insulation, helping the dolphin stay warm in cold water. Blubber also serves another function, streamlining the body for better speed in the water. Dolphins have a body covering of skin (not scales). The uppermost layer of the skin produces an oil which forms a film that covers the dolphin's whole body. Being mammals, dolphins breathe with lungs rather than gills, so they breathe from a blowhole which closes before the dolphin goes into the water, so water will not enter the blowhole. The long nose helps the dolphin to kill sharks. Dolphins have teeth, which they use to catch fish. Dolphins have large brains in relation to the size of their bodies, and studies show they have exceptional intelligence. Dolphins work together to find food, often "herding" school of small fish up onto reefs and sandbars. The dolphins then work together, taking turns to feed while the other dolphins keep the fish herded. Dolphins have well developed echolocation, by which they locate other animals and objects in the water. It is also how they communicate with each other. Dolphins have between 45 and 63 small, sharp teeth, which enable them to tear food into smaller pieces. Dolphins sleep with just part of their brain, so that the other part remains constantly on alert for danger.
Do river otters kill beavers?
This information is according to information from Wikipedia Mammals are rarely consumed by river otters and are not a major dietary staple.Mammals that are preyed upon by otters are characteristically small or are a type species found in riparian zones.[The few occurrences of mammals found in the river otter's diet include: Muskrats (Ondatra zibethicus); Meadow Voles (Microtus pennsylvanicus); Eastern Cottontails (Sylvilagus floridanus); and Snowshoe Hares (Lepus americanus). There are varying records of otters preying upon beavers (Castor canadensis). Otter predation on beavers has been reported in the southern boreal forest of Manitoba.Trappers in Alberta, Canada commonly assert that otters are major predators of beavers.A 1994 river otter study reported findings of beaver remains in 27 out of 1,191 scats analyzed.However, many other studies did not report any findings of beaver remains in the scat sampled. (Scat is animal droppings) Other web sites also say that river otters will sometimes kill muskrats or beavers to take over their dens/lodges. Survival of the fittest.
Do wolves hunt mostly during daytime hours?
Asked in Animal Behavior
Why do animals move in different ways?
Animals have different body structures, so they move differently. They have different structures because of MANY years of evolution. Animals living in different areas with different landscapes had to get around differently, so they adapted. And they also had to get food from hard-to-reach places, so they adapted. Like a giraffe has a long neck for tree leaves and a wolf has long legs to chase and catch prey. Monkeys have those flexible limbs for climbing and tails for balance while dwelling in the high trees. The simple answer is: different body structures. But the have different body structure because they had to adapt. Living creatures move differently because they have different body structures. They have longer legs, shorter legs, stronger or weaker muscles that allow them to run faster or jump higher or faster or no legs at all so they have to crawl, and they have longer, shorter, stronger, or weaker arms. All this as a result of adpating and evolving over thousand or millions of years, or maybe they were designed and created that way. Even with the belief of creation, there is evidence that animals did adapt and change, or there are signs that species that were known have disappeared and new ones exist that were not previously known. Animals are believed to have adapted over time to conform to the requirements of their environment, to be able to get food, and to be able to not be food. This does not mean animals grew flexible limbs for climbing and tails for balance so they could become monkeys dwelling in the high trees. It means that some animals were born and grew up with genetic mutations that allowed them to live in tree and hide from ground based predators. They had a better chance to survive and propogate than earlier versions of the same animal that were stuck on the ground.
Asked in Animal Behavior
What is a wild animal's lair?
A lair is defined as a home or habitat in which an animal lives in. So, where an animal lives or coexists would depend on the type of animal. For example: Apes typically live in tropical rainforests. Sharks dwell and coexist underwater. Birds spend most of their time flying in the sky; in general, birds tend to build their homes in hollow-trees so that they're closer to their homes. So a wild animal's lair simply is where it lives and coexists with others of the same species.

Asked in Whales, Animal Behavior
Why do birds migrate and animals hibernate?
Birds such as Geese and Ducks migrate due to the cold tempuratures in the Northern states, causing the lakes and rivers to freeze over, making it impossible to land on the water to reach their main and almost only source of food, weeds and small fish. Birds such as Robins migrate because their main diet consists of berries and nuts, and usually they are not available during the winter and therefore must migrate to the South where the berries grow year-round. However, animals like bears hibernate since they don't have the time or strength to travel such long lengths to reach warmer climates, and therefore stock up on as much food as they can in their bellies before going into a long slumber in a protected and supposedly warmer location like a cave or hole in the ground
Asked in Cows and Cattle, Animal Behavior
How do you make cows trust you?
Be the one providing feed and treats for them. Soon they'll get to know you and even trust you. Another answer: Always be gentle and calm around them. It helps to talk or hum continually around them so you never surprise them. Stay in their field of vision as much as possible. Let the cows do things at "cow speed" and don't try to rush or harry them. Some breeds and individual cows have calmer dispositions as an inherited trait, so you may be able to choose a cow that is more likely to trust you.
Asked by Taya Moore in Cats (Felines), Animal Behavior
Why do cats headbutt you?
When cats headbutt you, they’re depositing facial pheromones. Vets call this behavior bunting. “Rather than territorial marking or ‘claiming’ someone, as is commonly thought, cats do this to mark something as safe—sort of like leaving a signal of comfort and safety. So you could think of it as a sign that they are trusting that person or environment,” Dr. Meghan E. Herron, clinical assistant professor of behavioral medicine in the Department of Veterinary Clinical Sciences at Ohio State University, told Vetstreet.
Asked in Animal Behavior, Orcas (killer whales)
Are killer whales violent?
Killer whales are wild animals and so should be treated with respect. They do not always kill everything they see, and there have been very few cases of Orcas (Killer Whales) harming humans in the oceans, despite divers having filmed their social behaviour while in close proximity. They have a highly developed social structure and research now suggests they share a common language. There have been recent occasions of Orcas acting violently in captivity although with their high intelligence they probably detest being captive.
Do skunks hibernate?
Skunks, like bears, go into a state of torpor. This is a very groggy sleep that is intermittent and can be interrupted by periods of time awake and active. Hibernation is a physical state where the body significantly drops in temperature and the creature is immobile for a very long time. A hibernating animal almost looks dead and takes a very long time to wake up. An animal in torpor can be woken more easily, which is why it isn't safe to disturb bears who are in torpor sleep for the winter. Skunks take long torpor naps in their dens, and females often in groups. They will wake to look for food on warm days, and will need to come out of the den at least once to empty their scent glands. This would explain why folks sometimes see, or smell, skunks during the winter months.
