No single feature distinguishes Annelids from other invertebrate phyla, but they have a distinctive combination of features. Their bodies are long, with segments that are divided externally by shallow ring-like constrictions called annuli and internally by septa ("partitions") at the same points, although in some species the septa are incomplete and in a few cases missing. Most of the segments contain the same sets of organs, although sharing a common gut, circulatory system and nervous system makes them inter-dependent.[5][9] Their bodies are covered by a cuticle (outer covering) that does not contain cells but is secreted by cells in the skin underneath, is made of tough but flexible collagen[5] and does not molt[15] - on the other hand arthropods' cuticles are made of the more rigid α-chitin,[5][16] and molt until the arthropods reach their full size.[17] Most annelids have closed circulatory systems, where the blood makes its entire circuit via blood vessels.[15]
Its boobies
Most Annelids live in the soil. They eat food which is available in the soil. Examples of Annelids are earthworms.
Annelids are segmented worms such as earthworms or nightcrawlers. They can be found in most fertile soils and other moist or wet areas.
