Thus, many deep-sea species will grow in the comparatively shallow depths of the Sound.
But gathering and sustaining these delicate, deep-sea species is far from simple.
It is a deep-sea species of the order Lophiiformes (anglerfishes).
The Stephanoberyciformes are mostly uncommon deep-sea species with little, if any, importance to commercial fishery.
The number is likely to be considerably higher if all micro-organisms, cave-dwellers and deep-sea species were counted.
Even some deep-sea species of hydromedusae and scyphomedusae are usually collected on or near the bottom.
Both shallow water and deep-sea species of brittle stars are known to produce light.
These deep-sea species are found and are endemic at hydrothermal vents.
This proposal introduces elements of a system for the management of fishing effort directed at these deep-sea species.
Many deep-sea species have reduced eyes, and reduced movement of the eyestalks.
