'Cookie Cutter Shark Facts\r'

'Cookie stonecutter shark ————————————————- Features: The Cookiecutter chisel combines many specialized features that enable it to carve out a living in the deep-sea. Like many mesopelagic sharks, it has an elongated body cavity filled with an enormous colored comprising as much as 35% of its total weight. The Cookiecutter’s liver is perfused with low-density oils which render the shark nearly neutrally blessed over a wide range of depths and thereby saves energy by freeing it from the need to float constantly to avoid sinking.It has actually large eye †the better with which to see potential prey †and a short, broad caudal fin that is ideal for fast bursts of acceleration over short distances †that is, ambushing prey from block range. ————————————————- Hunting ab ilities: To lure prey inside range, the Cookiecutter Shark relies on its brilliant luminescence. Complex light-producing organs called â€Å"photophores” ar scattered over the Cookiecutter’s entire body and argon especially richly distri stilled on its paunch and lower surfaces.A main function of this pattern of light organs is to eliminate an animal’s derriere as seen from below, a common mesopelagic anti- maraudery strategy cognize as â€Å"counter-illumination”. But there is a very curious fact about the distribution of photophores on the Cookiecutter Shark’s undersurfaces: they are completely slay from the region under the throat between the gill slits. It has recently been proposed that this dark patch that is bordered by luminescent organs may mimic the count image of many upward-looking pelagic predators.Thus, when a manque predator approaches what appear to be a petite shadow of a potential prey animal, it is brought within the str iking range of the insidious Cookiecutter Shark and the predator has become prey. ————————————————- Humans who, by accident or by design, enter the unsolved sea are not immune from attacks by Cookiecutter Sharks. The body of a drowned look forerman recovered ff the coast of Oahu, Hawaii, in July 1992 had dickens Cookiecutter bites to the lower back. These bites are believed to have been inflicted post mortem, but there are a few record reports of people †including shipwreck survivors and, in one case, an subaqueous photographer †being attacked in the tropical open ocean by schools of blunt-snouted and extremely ferocious foot-long (30-centimetre long) â€Å"fish” that neatly sliced out circular plugs of skeletal system about an inch (2. centimetres) in diameter. The fish creditworthy may well have been Cookiecutters. This frightening hap certainly puts the romantic notion of a moonlight swim in a whole naked as a jaybird light. ————————————————- ———————————————————————————————————————â€]\r\n'
