The Brown shark, also known as the Sandbar shark is commonly found in public aquariums. The genus name Carcharhinus is derived from Greek words meaning "sharpen nose". It is a coastal-pelagic shark that lives in temperate and tropical waters throughout the world. It is naturally a bottom-dwelling shark found in shallow coastal waters, and is known to be highly migratory. The Brown shark is an important species in commercial fisheries along the Eastern United States, and is the primary targeted species in this area. Because of its age at reproduction and the fact that it reproduces every other year producing a small number of young, the Brown shark is vulnerable to over-exploitation. Although rarely associated with attacks on humans, the size of the Brown shark makes it a potential threat.
Found in Panama and Colombia, this little bird has proved adaptable to disturbed habitats, flourishing in second-growth woods. The elongated feathers, arranged like a beard beneath the male's throat, can be bunched together like a pointing finger, parallel with its beak. With those feathers thus positioned, the male performs its courtship display by darting suddenly from branch to branch while making startling snapping sounds with its wings. The only captive hatchings have taken place at the DWA, with twelve hatchings since the first in 2009.
Carl Linnaeus (1707-1778) invented the scientific names we use today. Many of his names were given to dead specimens in European museums, or pictures in books, so the information he had was sometimes incorrect. The laws of nomenclature do not allow for corrections. Thus, even though this large finch actually comes from Panama and Northern South America, the "Canadian" name that Linneaus gave it in in 1766 is still used. A relative of the Cardinal, Rose-breasted grosbeak, and Painted and Indigo buntings, it has always been rare in captivity.
