Animal Info - Glossary B
- A horny substance, commonly known as whalebone, that grows as plates from the upper jaws
of certain whales, and forms a fringelike filter for extracting plankton such as krill and small fish from seawater.
- Baleen Whale
- Any of several whales of the suborder Mysticeti, such as the right
whale and rorquals, having a
symmetrical skull, two blowholes, and baleen plates
instead of teeth. Also known as a "mysticete."
- Bamboo species are giant grasses that have evolved woody stems and tough, leathery
leaves to deter predation. Because they are so high in indigestible fiber and are
loaded with abrasive compounds containing silica, bamboo's are difficult to eat and to
digest. (Roberts 1992a)
- A barrage is a relatively low, gated dam built across a river to regulate water discharge. In the
Asian subcontinent, barrages are primarily used to divert water into canals for irrigation
and sometimes to facilitate navigation. During monsoon season flows, the gates are
generally left open. They are then progressively lowered as the flood recedes.
- Benign introduction
- An attempt to establish a species, for the purpose of conservation, outside its recorded
distribution, but within an appropriate habitat and eco-geographical area.
- Referring to an animal that lives on the bottom of a body of water.
- Beta diversity
- See diversity - beta.
- A measure of the abundance of an animal (or group of animals, plants, etc.) in term of
the mass ("weight") of the animals, stated as either the total mass of the
animals in a given location or per unit area.
- Bioturbation is the disturbance of sediment layers by biological activity.
It is a significant process on the ocean floor. In that environment,
numerous animals such as worms exist by consuming organic matter trapped
between sediment grains. Animals like clams burrow through sediment to hide
from predators swimming or crawling above the ocean floor. Either activity
requires the animals to burrow through the sediment, destroying some of the
pre-existing sedimentary features.
- Referring to animal that walks on two legs.
- Black water
- Several different types of water occur within the Amazon River basin. Clear, non-turbid, acidic, "black" water is derived locally
from drainage of the forest and is colored by tannin from
the breakdown of vegetation and high concentrations of dissolved organic humic acids.
Black water areas are grayish black in color.
- The opening of the nostril(s) of a whale, located on the top of it's head, through which
the whale breathes and from which the "spout" is produced.
- A layer of fat beneath the skin.
- Referring to northern regions. Specifically, the region south of the Arctic Circle and
north of latitude 50 deg. N; the term may also refer to an area dominated by coniferous forest.
- Borneo is the third largest island in the world. Politically divided
between Brunei, Indonesia
and Malaysia, it consists of the the
sultanate of Brunei (Brunei Darussalam) in
two unconnected parts; the Indonesian
provinces of East, South, West and Central Kalimantan; and the Malaysian
states of Sabah and Sarawak. (Wikipedia)
- A member of the artiodactyl family.
Members of this family have unbranched horns comprising a layer of keratin
surrounding a bony core. These horns are never shed, as opposed to the
antlers of deer. Bovids also have divided ("cloven") hooves and
chew their cud (utilizing a 4-chambered ruminating
stomach). Bovids include cattle, oxen, bison, buffaloes, sheep, goats and antelopes
(which include gazelles).
- To move around in trees by arm-swinging beneath branches.
- Somewhat salty.
- Leaping headfirst from the water surface (usually by whales).
- Having inconspicuous dark streaks or flecks on a gray or tawny background.
- One of a family of American epiphytic herbaceous plants including the pineapple and Spanish
- Tender shoots, twigs, and leaves of trees and shrubs used by animals for
- A herbivore that feeds on shoots and leaves of trees
and/or shrubs, as opposed to herbaceous
vegetation (compare "grazer").
- A natural region in southern Africa. It is an extensive grassland with
thorn bushes and with scattered trees, such as acacia and baobab. It is moderately dry and has an elevation of about 800 - 1,200 m (2,500 - 4,000'). (Also
- A large, ground-nesting bird.
- Fish taken in a fishery which are not of the species intended for harvest.
