The Yellow Sea Potata, Heart Urchin, scientifically known as Echinocardium flavescens, is a species of sea urchin belonging to the family Loveniidae. This fascinating creature is widely distributed in various marine environments and plays a crucial role in its ecosystem.
Description & Characteristics
Echinocardium flavescens, also known as the Heart Urchin, is characterized by its heart-shaped body, often exhibiting a yellow or brown hue. This species typically reaches a maximum size of 5-6 centimeters in diameter. As a member of the Spatangoida order, it possesses a flattened body with a distinct anterior-posterior axis, allowing for burrowing into soft sediments. Their bodies are covered with spines that aid in movement and protection.
Habitat and Occurrence
Echinocardium flavescens is a common inhabitant of the shallow coastal waters and the intertidal zone, preferring sandy and muddy bottoms. They are often found in depths ranging from the surface to 100 meters. This species is typically found in the neritic zone, which encompasses the shallow waters of the continental shelf. Their presence in this zone underscores their adaptation to environments influenced by sunlight and the presence of nutrients.
Taxonomy
Echinocardium flavescens belongs to the Class: Echinoidea, Order: Spatangoida, and Family: Loveniidae. This classification reflects its unique features, including its heart-shaped body, flattened body structure, and burrowing behavior. The Spatangoida order encompasses sea urchins that are adapted for burrowing in soft substrates, showcasing the specific adaptations of this species.
Feeding
Echinocardium flavescens is a detritivore, feeding primarily on organic matter and detritus found in the sediment. Their feeding behavior plays a vital role in the decomposition process, contributing to nutrient cycling and maintaining a healthy marine ecosystem.
