Greyhounds are commonly accepted as the fastest dogs in the world, but other breeds, such as salukis and border collies, are close in speed. Over very long distances, the Alaskan husky is probably the fastest dog in the world.
A:Some of the animals that eat salamanders include wild turkey, hawks, common crows, barred owls, raccoons, shrews, chipmunks, snakes, skunks, and any other animal that can find them under rocks, wood or running along in the leaves. There are many species of salamander living in a variety of locations across the country, making them an attractive food source for a wide range of small animals that like live prey.
A:Newts are generally found in North and South America and in the temperate areas of Africa, Asia and Europe. They prefer to live in moist areas near forests, under stones, in streams and under fallen logs.
A:A few examples of insectivores include moles, hedgehogs, moonrots, tenrecs and solenodons. Insectivores are a group of about 450 mammals that eat primarily insects, earthworms and arthropods. Although their name implies that they consume insects, they may also eat plants and other animals, including fish, crustaceans, amphibians, small vertebrates and the eggs of birds.
A:The American alligator is a large, heavily armored reptile armed with sharp claws, a strong tail and an enormously powerful set of jaws lined with conical teeth. As apex predators, alligators have no natural enemies but can rely on these features for defense.
A:Also known as the cane toad or giant toad, the marine toad is a land-dwelling toad native to Central and South America. The toad spends its time in the region's subtropical forests and has also been introduced to non-native areas as a means of pest control for crops.
A:Amphibians are cold-blooded vertebrates. They have a backbone, and they maintain their body temperature through external means, such as laying in the sun. Amphibians spend part of their lives on water and part of their lives on land. They have permeable skin, which gases and some molecules penetrate; they also have gills for some portion of their lives.
A:There are countless animals without tails, and all of them fall under the category of "invertebrates." Invertebrates are animals that don't have backbones (and therefore don't have tails either). Some examples include centipedes, insects, grasshoppers, butterflies, snails, octopuses, spiders, worms and scorpions.
A:There are few observable traits distinguishing migrating animals from non-migratory species. Many birds, such as Arctic terns, mallards and bar-tailed godwits migrate across vast distances, while some of their close relatives remain in the same place all year. There are species of birds, fish, mammals, and even reptiles and amphibians that migrate each year.
A:Most fish breed by spawning, or laying eggs, according to Petalia. Some fish species give birth to live babies. Spawning fish reproduce when males fertilize the eggs after they are laid, while livebearing females are directly fertilized by the males.
A:The common tenrec — a hedgehog-like creature from Madagascar — produces the largest litters among mammals. The average litter of this small animal includes approximately 18 young, but litters up to 32 have been recorded. Tiger snakes also produce very large litters; the largest ever recorded contained 126 baby snakes.
A:According to About.com, most land snails are hermaphrodites. Following courtship in early summer, a pair of snails inseminate each other through a reproductive opening located near the front of the body, resulting in fertilized eggs.
A:Ducks and some other birds stand on one leg, called unipedal resting, to help regulate and maintain body temperature. A bird on ice reduces the amount of unfeathered surface exposed to the elements by standing on one leg.
A:In the wild, ostriches have demonstrated top running speeds of more than 40 mph, according to the National Wildlife Federation. The ostrich is the largest bird in the world and relies on its speed in order to outrun predators.
A:Despite having wings, not all birds can fly. There are several types of flightless birds, including the penguin, kiwi, moa, weka and kakapo. Kiwis for Kiwi, an independent charity that protects the kiwi populations in New Zealand, states that there are more species of flightless birds in New Zealand than in any other country.
A:A lutino lovebird is a color mutation of Agapornis roseicollis, the peach-faced or rosy-faced lovebird. Lutino lovebirds have bright yellow feathers, whereas the standard coloration of lovebirds is green feathers.
A:Mosquitoes have four teeth that are sharp and serrated. They are arranged around two tubes. One releases a pain suppressor into the insect's victim, as well as an anticoagulant to keep the blood from clotting. The other tube draws out the blood. Only female mosquitoes feed on blood.
A:Sun scorpion is another name for a camel spider. The camel spider is not truly a spider; it is an arachnid known as a solpugid. These animals are closely related to scorpions and spiders, but they do not sting or carry venom.
A:The Armadillidiidae vulgare, known commonly as a potato bug or pill bug, has a diverse diet that includes decaying matter, vegetables, cardboard and even their own fecal waste. Eating their own fecal matter provides them with a consistent recycling of the mineral copper, which they need to survive.
A:Mayflies from the order Ephemeroptera live anywhere from a few hours to a few days as adults depending on the species, with many species living approximately one day after moulting and breeding. In the juvenile stage, mayflies live for months or years in the water, gradually moulting into adults.
A:According to the Center for Disease Control, the common household centipede has a poisonous venom that is not considered toxic to most humans, though the bite is often painful. Smaller children and persons with bee sting allergies face potential anaphylactic shock if bitten by larger centipedes.
