Henricia obesa is a species of starfish belonging to the family Echinasteridae. It is commonly known as the “obese Henricia,” reflecting its characteristic plump and rounded body shape. This starfish is a fascinating inhabitant of the marine environment, showcasing unique adaptations for survival in its chosen habitats.
Description and Characteristics
Henricia obesa exhibits a distinctive, robust appearance. Its body is typically plump and rounded, with a maximum size of around 5 centimeters in diameter. The color of this starfish varies depending on its location and environmental conditions. Some specimens exhibit a rich orange hue, while others display a more muted reddish-brown coloration. The surface of the starfish is covered in numerous, small spines, which contribute to its rough texture. These spines are arranged in distinct patterns, adding to its unique visual appeal.
Habitat and Occurrence
Henricia obesa is a common inhabitant of the intertidal zone and shallow subtidal areas. It is particularly prevalent in rocky habitats, often found clinging to the undersides of rocks or crevices. This species prefers locations with moderate wave action and good water circulation, conditions that contribute to its abundant presence in these ecosystems. Henricia obesa can be found in various marine zones, including the neritic zone, which encompasses the shallow waters along coastlines. The species’ preference for rocky habitats and its tolerance for a range of water depths and conditions make it a widespread inhabitant of these coastal regions.
Taxonomy
Henricia obesa belongs to the Class Asteroidea, the class of starfish, and is classified within the Order Spinulosida. This order includes a diverse array of starfish species characterized by their spiny surfaces. Henricia obesa is further grouped within the Family Echinasteridae, a family known for its often plump and rounded body forms.
Feeding
Henricia obesa is a carnivorous species, feeding primarily on a variety of small invertebrates, such as barnacles, mussels, and other mollusks. Its diet reflects its adaptations for life in the intertidal zone, where these prey items are readily available. The starfish uses its tube feet to pry open the shells of its prey, consuming the soft tissues within.
