Pink Temnopleurid Sea Urchin, Short-spined Urchin – Amblypneustes elevatus

The Pink Temnopleurid Sea Urchin, Short-spined Urchin, scientifically known as Amblypneustes elevatus, is a fascinating marine invertebrate belonging to the class Echinoidea, commonly referred to as sea urchins. This species is distinguished by its vibrant pink hue and relatively short spines, which set it apart from other sea urchins.

Description & Characteristics

Amblypneustes elevatus, also known as the Short-spined Urchin, typically reaches a maximum size of 5-6 cm in diameter. Its body, or test, is covered in numerous short, blunt spines that are typically pink in color, although they can sometimes appear more reddish or purplish depending on the individual and its environment. The spines provide protection and aid in locomotion, allowing the urchin to navigate its habitat. The test is also characterized by a series of pores, which are openings for tube feet, that help the urchin move and gather food.

Habitat and Occurrence

Amblypneustes elevatus is a common sight in the tropical waters of the Indo-Pacific region. It is typically found in shallow, intertidal zones, particularly in rocky areas and coral reefs. This species can often be seen inhabiting the Indo-Pacific region’s reefs and rocky shores, thriving in the warm, clear waters of these marine environments.

Taxonomy

Amblypneustes elevatus belongs to the family Temnopleuridae, which is a diverse group of sea urchins known for their compact, often colorful tests. Within the class Echinoidea, this species is categorized under the order Camarodonta, a group that includes many of the more familiar sea urchins. This classification reflects the unique evolutionary history of this species and its relationships with other sea urchins.

Feeding

Amblypneustes elevatus is an omnivorous species, meaning it consumes a variety of food sources. Its diet typically consists of algae, detritus, and small invertebrates, which it gathers using its tube feet and mouth, located on the underside of its body. This flexibility in its diet allows Amblypneustes elevatus to adapt to different food availability within its habitat.
