An area of water bordered by land on three sides.
A major class of ecologically similar communities of plants, animals, and other organisms. Biomes are defined based on factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and other factors like climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation.
Body length (VT)
The distance from point to point along the longest axis of the body of an organism.
The amount of matter in the body of an organism.
An animal that mainly eats meat.
Single birth offspring quantity. The proportion or number of offspring produced from a single pregnancy (mammals) or ovulation (fish) or nesting (birds).
An area of flat, low-lying land adjacent to a seacoast and separated from the interior by other features.
The seabed below the end of the continental shelf (the shelf break). The continental slope is much steeper than the shelf; the average angle is 3, but it can be as low as 1 or as high as 10. The slope is often cut with submarine canyons.

A description of the geographic distribution, or range, of the taxon. Includes descriptions of global, regional, or political aspects of range and whether the taxon is native or introduced in portions of the range and endemicity.
Gestation period duration
The length of time between when a fertilized egg implants in the wall of the uterus and the birth of offspring.
A category or description of the habitat in which the Event occurred.

Total life span
The full period of time from birth to death of an organism.
The position an organism occupies in a food chain.
