Animals and Their Differences

Animals are multicellular, living organisms in the animal kingdom. With few exceptions, animals eat organic matter, breathe oxygen, can move, reproduce sexually, and secrete body fluids. They also have nervous systems, which enable them to communicate with other animals and with humans. Most animals use at least a little of their brain and nervous system to interact with other animals, plants, and even themselves. But animals also have brains that perform many functions, such as determining when an animal is hungry, calming an animal that is stressed out, or determining when an animal needs to seek protection from predators.

Blastula (Euphorbia pachidermatys) is a ciliate with a long tail. Small to medium sized, it lives in bodies of fresh water, running from sea to ocean, and throughout all of the oceans of the world. It forms shells for tiny animals (including some crustaceans and fish), collects organic materials as it feeds, moves from one marine environment to another, and excretes shell parts as part of its reproductive process.

Arthropods, which include all animals and insects of the class Insecta, belong to the Kingdom Protista. Insects are small to large in size, with the exception of bees and butterflies. Bees are the most common type of mammal, and almost all insects are vital to the existence of plant life. In fact, without insects, life on earth would be nearly impossible.

Mollusks and snails belong to the class cnidaria, which are members of the class cephalopods. Mollusks are segmented bodies of soft tissue that are used in the process of feeding. Snails, on the other hand, are bony, multicellular organisms that are directly related to arthropods. They have jointed cell walls, and their body can be found in a number of places.

Arthropods and animals make up the kingdom Animalia, which is the entire order of living beings. Animalia includes all of the animals and creatures that are in the class Cephalopods. The word “animalia” comes from the Greek word that meant “animal” and “plant”. Some of the animals in this kingdom are known as fur, hair, fur-producing animals, and animals that secrete milk.

Lamarckia is the only exception to the rule that animals are only in one kingdom. Its representatives are all insects, which are classified in two types of families, Cimicidae and Orthoptera. All vertebrates and many invertebrates are also in this kingdom. The three branches of the Phylum Arachnida, which includes all of the insects and mollusks as well as some crustaceans and fishes, make up the classifications of animals. There are three types of lamins, the most famous of which is the carotene, which gives both yellow and orange color to animals.
