Echinometra oblonga, also called the oblong urchin or 'ina 'ele 'ele (ina= generic name for urchin, 'ele 'ele= blackish) in Hawaiian, is a very common rock boring urchin on shallow rocky shores of the tropical Indo-Pacific and Southern Africa.[2]
Description
[edit]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
[edit]Echinometra oblonga, are gonochoric.[4] They fertilize externally. Their eggs are either held on the peristome or around the periproct.[4]
Habitat
[edit]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]
