Benthonic
Organism lives on or in the sediment substrate of the sea floor
1 of 8
Infaunal
Organism lives in the sediment, usually in a burrow. Many will filter feed. (e.g. a bivalve clam)
2 of 8
Epifaunal
Organism lives on the sediment substrate. (e.g. a bivalve oyster)
3 of 8
Vagrant
Organism moves around on the sea floor and is usually a scavenger or predator. (e.g. a regular echinoid)
4 of 8
Sessile
Organism does not move around on the sediment substrate. Some are attached to the sea floor others lie on the sea floor. Most will filter feed. (e.g. a bivalve mussel)
5 of 8
Pelagic
Organism lives in the water column typically in the surface layers
6 of 8
Planktonic
Floats in the water column to wherever the currents will take it. Usually a filter feeder. (e.g. a graptolite)
7 of 8
Nektonic
Actively swims in the water column. Most are scavengers or predators. (e.g. an ammonite)
