Creatures of the Night | Worldwide Animals

Nocturnals

There are some 15 species of hedgehog in Europe, Asia, and Africa. Hedgehogs have also been introduced into nontraditional ranges such as New Zealand. The hedgehog was named because of its peculiar foraging methods. These animals root through hedges and other undergrowth in search of the small creatures that compose the bulk of their diet—insects, worms, centipedes, snails, mice, frogs, and snakes. As a hedgehog picks its way through the hedges it emits piglike grunts—thus, the hedgehog. Some people consider hedgehogs useful pets because they prey on many common garden pests. While on the hunt, they rely upon their senses of hearing and smell because their eyesight is weak. Hedgehogs have a coat of stiff, sharp spines. If attacked they will curl into a prickly and unappetizing ball that deters most predators. They usually sleep in this position during the day and awaken to search for food at night. Hedgehogs hibernate in cold climates. In deserts, they sleep through heat and drought in a similar process called aestivation. They remain active all year in more temperate locations. These solitary animals typically couple only for mating. The young born each year, in litters ranging from one to eleven, remain with their mothers for only four to seven weeks before heading out on their own. Among the predators females must guard against during this period are other male hedgehogs, which will sometimes prey upon the young of their species. Hedgehog mothers have also been known to eat their young if the nest is disturbed, though they sometimes simply move them to a new nest.

The ghostlike snowy owl has unmistakable white plumage that echoes its Arctic origins.

These large owls breed on the Arctic tundra, where females lay a clutch of 3 to 11 eggs. Clutch size depends upon the availability of food, and in particularly lean times a usually monogamous pair of owls may not breed at all. Parents are territorial and will defend their nests against all comers—even wolves.

Young owls, especially males, get whiter as they get older. Females are darker than males, with dusky spotting, and never become totally white. Some elderly males do become completely white, though many retain small flecks of dusky plumage.

The snowy owl is a patient hunter that perches and waits to identify its prey before soaring off in pursuit. Snowy owls have keen eyesight and great hearing, which can help them find prey that is invisible under thick vegetation or snowcover. The owls deftly snatch their quarry with their sharp talons.

A snowy owl's preferred meal is lemmings—many lemmings. An adult may eat more than 1,600 lemmings a year, or three to five every day. The birds supplement their diet with rabbits, rodents, birds, and fish.

These magnificent owls sometimes remain year-round in their northern breeding grounds, but they are frequent migrants to Canada, the northern United States, Europe, and Asia. Lemming availability may determine the extent of southern migration, when owls take up summer residence on open fields, marshes, and beaches.

Sugar gliders are small furry animals native to Australia, New Guinea and some surrounding islands. Their name also serves as a short description of them, they like to eat practically anything sweet, and they have a membrane that stretches from their hands to their feet which allows them to glide. Sugar gliders are kept as pets by a large number of people, but because of their habits, needs, and legality in some states, they are fairly uncommon. In the wild sugar gliders eat a variety of plants and insects. During the summer when insects are abundant, insects make up the majority of diets. In the winter when insects are less abundant they rely more on plants such as acacia gum, eucalyptus sap and various nectars. Sugar gliders will also eat manna, a sugar left behind from sap flow, and honeydew, a sugar left behind by insects. When kept as pets sugar gliders are commonly fed fruits and vegetables, pellets, vitamins, calcium supplements, mealworms and crickets by their owners. Diet is one of the biggest challenges to a sugar glider owner as it is hard to simulate the exact diet that sugar gliders get in the wild. It is one of the reasons that sugar gliders are somewhat rare as pets is many people would rather not store live mealworms and other insects in their homes.

Scorpions are arthropods, they have eight legs, two pedipalps, and a tail with a venom-injecting barb. Scorpions have two venom glands that produce venom used in hunting and self defense. Scorpions do not have bones instead they have an exoskeleton made of chitin, the same thing our fingernails are composed of.
Scorpions are found all across the world. There are over 2,000 different species found on six of the seven continents. They prey on insects, arthropods and in some cases small vertebrates. Because scorpions can live in such hash environments they have adapted the ability to slow their metabolism to as little as one-third the rate for most arthropods. This enables some species to use little oxygen and live on a single insect a year. Even with lowered metabolism, the scorpion has the ability to spring quickly to the hunt when the opportunity presents itself something that many hibernating species are unable to do. Some species can have over 100 viviparous offspring, followed by the young climbing on the mother's back for weeks until first molt and living independently. All scorpions are venomous, they use their venom to paralyze and kill their pray and in self defense. Even small young scorpions can inject you with the same amount of venom as adults.
