What are the species invertebrates?
Invertebrates are animals without spines. They have a number of possible body shapes and fall into many different animals of animals, including insects, jellyfish and worms. Invertebrates are considered to be more primitive evolutionary than vertebrate animals and the variety between different species is much more extreme. Most experts agree that approximately 96% of all animals on the planet are invertebrates.
Invertebrate animals fall into eight different subtypes. Some of the more well -known types are arthropods, nematodes, molluscs and Annelids. Arthropods are insects, arachnids and crustaceans and are the largest species of invertebrates. Molluscs are also very common and include snails and octopus. Nematodes are round worms and annelids are segmented worms like earthworms and leeches.
Inverterbrates serves important purposes in terms of planetary ecology. For example, many crops are fertilized by invertebrates and wijejich, most of the agricultural efforts of humanity could be potentially destroyed. Are also an important source of food for creation across the planet. Many mammals, including humans, consume a large number of invertebrates, and if the population of invertebrate species should suffer, starvation would be for many kinds of options.
Some species of invertebrates can also be harmful to people, and many of the most dangerous parasites in the world are members of the invertebrate family. Some of the more well -known parasites of invertebrate include ticks, fleas and leeches. There are also parasites such as tapeworms that live in the body of their hosts, and these can be potentially even more dangerous than their external counterparts. Some parasites, as mosquitoes, may be particularly harmful because they can potentially carry diseases.
Most species of invertebrate species pass through the process of their development are called metamorphosis. This is useful because animals can fill different ecological niches at different times in development, allowing maximum use of food opportunities. During eachThe longer phases of its life will be an animal undergoing metamorphosis in general to have a completely different lifestyle and survive in a different way. A common example of metamorphosis would be a caterpillar that would create a protective cocoon and turn into a butterfly.
Invertebrate species can vary very much. Most of them are relatively small, such as insects and mites. Others, like some octopus and octopus, can be quite large. The largest existing invertebrates are Architeuthis, also known as a giant octopus that can be potentially 65 feet (20 meters) in length. Other invertebrates, such as a cilled protozoan, are too small to see them with the human eye.
