Datatype

Enumeration

Definition

The geographic distribution of marine organisms defined by historical events (for example: migration, extinction, or speciation).

Description

For example, the geographic region used by marine species during a portion of their life cycle (spawning, feeding, nursery, migration, and shelter), but most habitats support only a subset of these activities. Marine species may change habitats with changes in life history stage, seasonal and geographic distributions, abundance, and interactions with other species.
