Description

Echinometra oblonga shows a range of color from dark purple to black. Their spines are shorter, and more blunt than other species of Echinometra . [3]

Reproduction

Echinometra oblonga, are gonochoric. [4] They fertilize externally. Their eggs are either held on the peristome or around the periproct. [4]

Habitat

Echinometra oblonga generally live in rougher-water areas of tropical reefs. [2] To protect themselves from the force of the waves, they live in the holes of the reef, but they also live on exposed reef flats. [2] As the urchin grows, they use their jaws to help enlarge holes in the reef. Their spines trap seaweed and algae from the reef, which they then transfer to the mouth. [2]
