description Mesocentrotus nudus Overview
Mesocentrotus nudus is a regular sea-urchin belonging to the Strongylocentrotidae family. It inhabits kelp forests of the North Pacific, specifically around Japan. This species is notable for its prevalence and role in the ecosystem. Scientists study it to understand urchin populations and their impact on marine environments.
It's primarily relevant to marine biologists and researchers investigating coastal biodiversity.
help Mesocentrotus nudus FAQ
Where is Mesocentrotus nudus commonly found?
This sea urchin inhabits rocky coastal waters of the northwestern Pacific, including areas around Japan, Korea, China, and the Russian Far East. It often lives where kelp and other large algae provide food.
Is Mesocentrotus nudus harvested as food?
Yes. Its gonads are eaten as uni, making the species commercially important in parts of East Asia.
How does Mesocentrotus nudus affect kelp forests?
It grazes on kelp and other algae, helping shape coastal plant communities. When urchin numbers become too high, sustained grazing can contribute to barren rocky areas with little remaining kelp.
Why was this urchin formerly called Strongylocentrotus nudus?
Older scientific literature commonly places it in the genus Strongylocentrotus. Later taxonomic work recognizes it as Mesocentrotus nudus, so both names appear in fisheries and ecological sources.
