Snails have distinctive teeth called radulae or radulas, which range from a few to thousands. The radula is unique to mollusks such as snails, making these one-piece shell carriers the animals with the greatest number of teeth.
A:Tropical islands often harbor invertebrates, such as crabs and insects, as well as a variety of birds. Some tropical islands are even home to reptiles, amphibians or large mammals. The animals that inhabit tropical islands vary based on the island’s location, how far it is from land, whether or not people visit the island and the island’s geological history.
A:Fruit flies are among the smallest members of the Order Diptera and have large, pronounced compound eyes, oval-shaped bodies and a set of four wings, much like larger flies. Fruit flies average approximately 1 millimeter in length, and females are slightly larger than males. They closely resemble many fly species in appearance, sharing the same unique body shape, large wings and bulging eyes, but have several key biological differences.
A:The hippopotamus kills more humans than any other animal in Africa. This animal, which has an average weight of about 7,000 pounds, is responsible for 3,000 human deaths every year, according to the African Wildlife Foundation.
A:Characteristics common to all vertebrates include bilateral symmetry, two pairs of jointed appendages, outer covering of protective cellular skin, metamerism, developed coeloms and internal skeletons, developed brains, vertebrae and sensory organs. Vertebrates also have respiratory systems, closed circulatory systems, genital and excretory systems and digestive tracts.
A:The temperate forest is home to many different animals including several species of mammals, insects, birds, amphibians and reptiles. Skyenimals, a web source, gives a full list of the animals found in this habitat.
A:The scientific term for an animal that lays eggs is oviparous. The word comes from the Latin words "ova," meaning egg, and "parous," meaning bearing or producing. Animals that produce live young are called "viviparous."
A:The names of animals that are omnivores include humans, bears, badgers, hedgehogs, raccoons and squirrels. Omnivorous animals also include chickens, crows, pigs, wolves, dogs, catfish, piranhas, cockroaches, wasps and houseflies.
A:Rhinoceroses are herbivorous mammals, meaning they do not consume meat but subsist on plant matter only. They tend to eat whatever vegetation is available to them, and rhinos have adapted specific features to enable this kind of diet.
A:A simple group of fish is called a "shoal." It can contain a number of species. Shoaling makes it easier for fish to find food because more individuals are on the lookout. Large numbers also help fish find mates. In addition, being in a group offers some protection against predators, similar to hiding in a crowd.
A:A person who studies sharks is called a shark biologist. A shark biologist studies everything about sharks: their habitat, behavior, sexual reproduction, feeding, intelligence and more. Sharks are challenging to observe, and most shark biologists concentrate on researching a specific type of shark, often spending years researching.
A:As tropical waters are their native habitat, seahorses require stable tank temperatures ranging from 75 degrees Fahrenheit to 86 degrees Fahrenheit to maintain good health. They love to wrap their tails around structures and need a thin rope, vegetation, branches or coral for attachment. Wild seahorses prefer to feed on live shrimp and fish and often die of starvation in captivity if live food is not provided.
A:The appropriate scientific classification for any monkey is either "simian" or "primate." However, there are over 260 species of monkeys, not including hominids, that belong to the infraorder Simiiformes.
A:Insects belong to the largest phylum of the animal kingdom and are called arthropods. According to the Encyclopaedia Britannica, insects are members of the Arthropoda phylum and make up 84 percent of all the known animals on Earth.
A:A postanal tail is an extension of the spinal chord that extends beyond the animal's anus. Postanal tails are a feature of all chordates, which is a phylum that includes vertebrates. All chordates have a postanal tail at some point, but they may not have that tail for their entire lives.
