Black mambas eat small mammals found in their African range, including rodents such as squirrels and others such as hyraxes, along with occasional birds. They kill their prey with venom, striking twice and injecting a neurotoxin, and they do not eat until their prey is paralyzed or dead.
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.
Some general characteristics of amphibians are that they are cold blooded and spend at least part of their lives in water. Unlike reptiles, they lack claws and their smooth, moist skin is free of scales. Amphibians also lay jelly-covered eggs in a watery medium, whether it's a still pond or the leaves of a water plant like water hyacinth.
Frog Safe recommends keeping tadpoles in a short and wide container made of glass, plastic or Styrofoam. Cover the bottom of the container in sand about one-half inch deep. Fill the container with one liter of water per tadpole, preferably rain water. Underwater aquatic plants are essential for providing the tadpoles with oxygen. Feed them plant matter, protein and calcium: leaves with algae, baby spinach, bloodworms and crushed cuttlebones.
Tadpoles are aggressive eaters because of their rapid growth rate, and one of their favorite foods is algae that grows in pond water and along rocks. As they develop, tadpoles start to consume many microscopic water bugs, such as amoebae, fleas and rotifer.
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.
In rare circumstances, salamanders are known to bite humans. These amphibians only bite if they are under a lot of stress, and they may nip at a human if they are handled in a way that causes distress.
Polar bears reproduce via internal fertilization, with one male mating with several females during the mating season, staying with each for their three-day period of fertility. Mating occurs between late winter and early spring, after which gestation lasts anywhere between 195 and 265 days due to the females' ability to delay fetal development. Litter sizes range from one to four cubs but average two cubs per litter.
A giraffe is pregnant for about 15 months. During this gestation period, a mother giraffe often returns to the grounds where she was born to birth her own calf.
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.
During the mating season, the male peacocks use their colorful feathers to attract the female peahens. The males use their feathers to form a large train that is then maneuvered in courtship displays. The peahens choose peacocks depending on the color, size and quality of the feather trains.
The parts of an egg include the shell, the inner and outer membranes, the air cell, the albumen, the chalazae, the vitelline membrane, the yolk and the germinal disc. The shell is hard and porous and serves as a protective layer that allows gases to be transferred in and out of the egg.
Cockroaches reproduce by mating. When sperm from the male is introduced to the female's eggs, an egg sac called an ootheca is produced. The number of eggs the ootheca holds varies by species.
The differences between male and female blue jays are that males generally gather nest materials and food, while the females do most of the building of the nests and incubate the eggs. The differences between male and female blue jays can be determined by observing their mating and nesting habits. The size of males and females is similar, and they share similar feather colorings.
Toucans have predators. In the wild, they are prey for jaguars and other big cat species. Humans also capture toucans because they are popular pets. Toucans are known for their colorful, oversized bills.
Ostriches lack the ability to fly because their wings are far too small to generate sufficient lift for their 200-pound bodies. This is the same reason that their relatives, called the ratites, lack the capacity for flight. To cope with such an apparent competitive disadvantage, these birds have evolved large size and great speed. All ratites live in the Southern Hemisphere, and scientists believe that they share a common ancestor.
According to the United States Geological Survey, a group of doves is known as a dule, and a group of turtle doves is also known as a pitying. These collective nouns specifically describe groups of doves or turtle doves, though other words are suitable for describing three or more doves, including the words "group" or "flock."
According to National Geographic Kids, ostriches do not stick their heads in the sand. The misconception could stem from the unique physical attributes of ostriches, or it could be the result of their unusual actions during nesting or when frightened.
Like other birds, baby puffins can correctly be referred to as chicks. However, those who would like to be more specific may use the term 'puffling' to refer to puffin hatchlings.
Snails are not insects. They are members of the class Gastropoda, and are more closely related to squid than to the insects that live in gardens.
Breeding crickets is a relatively simple process that takes about 20 days to complete. Items you need include water, a spray bottle, a cricket habitat, and access to pairs of both male and female crickets.
When bitten by a mosquito, a person can expect to experience a red, raised bump that itches; these mosquito bites generally last only 24 hours, but can last longer according to WebMD. Those with allergies may have a prolonged healing time.
Earwigs do not bite or sting; they can, however, use their forceps to pinch people, but this rarely breaks the skin. The act of pinching is a last ditch effort when they are picked up and agitated. Earwigs, contrary to popular belief, pose no danger to humans and do not lay eggs in a human host's ears.
Sand fleas, also known as beach flies, sand hoppers or beach hoppers, are terrestrial crustaceans that belong to the Talitridae (Amphipoda) family. These small crustaceans look like tiny shrimp, but they are often mistaken for insects.
The African millipede is a large arthropod that grows 8 to 11 inches in length. The giant African millipede has a long body structure, and it has around 100 legs that are grouped into four legs on each segment of the body.
