| Scientists have speculated that as many as 10 million species may inhabit the deep sea — biodiversity comparable to the world's richest tropical rainforests. Because deep-sea species live in rarely disturbed environments and tend to be slow growing, late maturing and endemic, they are exceptionally vulnerable to extinction. Deep-sea coral and sponge communities are largely untapped sources of natural products with enormous potential as pharmaceuticals, enzymes, pesticides, cosmetics, and other commercial products. |
