[5], Smith and his colleagues suggested in 1989 that such species may use whale falls as stepping-stones to extend their range across multiple chemosynthetic communities. Whale corpses are known to serve as a host for animals that live in the bottom of the oceans. When the whale carcasses fall to the bottom of the sea, concretely in the bathyal or abyssal zone (at depths of 2,000 m or more), they are called whale falls. Cetacean definition is - any of an order (Cetacea) of aquatic mostly marine mammals that includes the whales, dolphins, porpoises, and related forms and that have a torpedo-shaped nearly hairless body, paddle-shaped forelimbs but no hind limbs, one or two nares opening externally at the top of the head, and a horizontally flattened tail used for locomotion. | You can also try the grid of 16 letters.

Because these samples were recovered by dredging, the complexity of whale- and wood-fall ecosystems was not recognized before the advent of deep-sea research vessels. When whales die and sink, their carcasses â known as whale falls â provide a bounty of nutrients for deepwater creatures. They hypothesize that this distance is short enough to allow larvae to disperse/migrate from one to another. The first examples of specialized invertebrates inhabiting bones and wood in the deep sea (qv) were recognized during the deep-sea expeditions in the early to mid 1900s.

Whaler definition is - a person or ship engaged in whale fishing. Whale falls have been thought to be âstepping stonesâ not only for dispersal of deepâsea chemosymbiotic species but also for the introduction over evolutionary time of chemoautotrophyâdependent invertebrates to vent and seep environments (Smith et al. [6] They may have survived in seeps, wood-falls and vents while waiting out the 20 million year gap between the reptiles' extinction and whales' emergence. When whales die, they sink to the seabed they become âwhale fallsâ and like phytoplankton, they take vast amounts of carbon with them helping to balance our climate. A few species of animals colonize the bones and surrounding sediments.
