The coelom of an earthworm is its body cavity. There are three categories for grouping animals according to their coeloms: coelomate (animals that have a true coelom lined by muscle tissue on both sides), pseudocoelomate (animals that have a coelom line by muscle tissue only on one side), and acoelomates (animals that do not have a body cavity lined by muscle tissue on either side). Earthworms are coelomate animals.
Earthworms belong to the Phylum Annelida and particularly the genus Lumbricus. The Phylum is characterised by body segmentation and a body cavity called acoelom. It includes marine worms, leaches and earthworms.The Earthworm belongs to the Phylum, AnnelidaEarthworms belong to the Annelida phylum.
sea anemone possess hydrostatic skeleton . Its cavity is filled with seawater to extend its body and tentacles . The sea anemone closes its mouth and contracts its muscle fibres that are arranged in circles around its body . The contraction of these circular muscles put pressure on liquid of the body cavity . This pressure forces the body to maintain upright position

Earthworms are coelomate animals.
The coelom in an earthworm serves several functions, including providing a space for organs to be suspended and protected, allowing for greater flexibility and movement, and serving as a hydrostatic skeleton to support the body and aid in burrowing. It also enables the earthworm to efficiently transport nutrients, gases, and waste throughout its body.
The downward projection in the oral cavity that triggers the swallow reflex when it receives contact is the epiglottis. It functions to cover the trachea during swallowing to prevent food or liquid from entering the airway.
