- n. The plants and animals that live in the sea-bottom, and those that are attached to its surface, and those that creep or run over it: a collective noun introduced by Haeckel. The benthos is contrasted with the plankton, or floating and swimming fauna and flora of the sea. It includes all the marine macrophytic algæ, also some phanerogams, the sea-grasses (see sea-grass, 1), as well as an abundance of microphytic algæ (diatoms, etc.). It is divided into the sedentary and the vagile or vagrant benthos, the former including organisms attached to the bottom, the latter those moving over it. See plankton, nekton.

Professor Joye and her colleagues used the Alvin submersible to explore the bottom-most layer of the water around the well head, known as the benthos.
New word: if you're one of those creatures that abides in the lowest level of a body of water (benthic zone), you are called a 'benthos'.
GQ is more "resilient" than other reefs due to it's protection, isolation, abundant predators, etc False Since the state of benthos in terms of coral and seaweed cover is far from exceptional, this argument isn't justified.
Despite some inaccuracies about the state of the benthos that I'll outline below, I thought the60 Minutespiecewas great for reef conservation in general.

Greenland halibut is commercially important in the North Atlantic and the Pacific, and is an important food item for deep-feeding marine mammals (e.g., narwhal and hooded seals) and sharks feeding on benthos such as the Greenland shark (Somniosus macrocephalus).
In the northern Bering and southern Chukchi Seas, primary production occurs over a shallow shelf (50 to 200 m) and as the zooplankton and bacterioplankton cannot fully deplete this carbon source, it is either transferred to the benthos or advected downstream .
An early bloom in cold melt water means most of the primary production goes to the benthos.
The change was predominantly from benthos to plankton and affected the overall diatom richness.
