Echinoids

Regular echinoids are a group of sea urchins characterized by their radial symmetry and typically spherical or slightly flattened shape. They belong to the class Echinoidea within the phylum Echinodermata. Regular echinoids have a rigid, calcareous exoskeleton called a test, covered in movable spines and tube feet.

Key Features:

Symmetry: Exhibit pentaradial symmetry, with a central mouth on the underside and an anus on the top.

Spines: Used for protection and locomotion.

Tube Feet: Part of the water vascular system, aiding in movement and feeding.

Diet: Most are grazers, feeding on algae and detritus.

Habitat:

They are found on rocky or sandy sea floors in marine environments, ranging from shallow coastal areas to deep ocean zones. Regular echinoids play important roles in marine ecosystems, particularly in controlling algal growth and contributing to the nutrient cycle.
