The photic zone, includes the open ocean influenced by light. The lower boundary is dependent on the depth of light penetration and is generally regarded extend to ca 200 m in depth. +
An organism that moves over the surface of sediment or lives at the sediment / water interface. +
Species that have been subject to an eradication event and have been confirmed as eradicated. +
Species that have been subject to an eradication event but have not been confirmed as eradicated. +
Species that have become established in their introduced range. +
Species that have become established in their introduced range and are known to be increasing in abundance and expanding their range. +
Species that have become established in their introduced range but are not known to be spreading aggressively. +
Downstream part of a river where it widens to enter the sea; often with significant freshwater influence and predominantly comprising sediment habitats. +
1) The region between the highest and lowest extent of the tide on the shore. 2) The shore zone between the lowest and highest seasonal water level in a lake (Lincoln ''et al.'', 1998) +

Egg/sperm meet and fertilize externally to parental individuals, tissues or confines of their bodies, but within the fluid medium +
A built-structure inhabited by an organism and essential to its survival, but not part of its body, composed of hardened (either rigid or flexible) secretions, with or without the addition of embedded particles, with those particles either selectively collected from the environment or passively becoming glued during formation (pers. comm. Read, G.). +
A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form. +
