Orca's Aggression
Orcas (or killer whales) are large, powerful apex predators. In the wild, there have been no reliably verified fatal attacks on humans. In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. Experts are divided as to whether the injuries and deaths were accidental or deliberate attempts to cause harm. Incidents with wild orcas There are a few recorded cases of wild orcas threatening humans. However, there have been no reliably verified fatalities. 1910s * In the early 1910s, the Terra Nova Expedition recorded that orcas had attempted to tip ice floes on which an expedition photographer and a sled dog team were standing. 1950s * There are anecdotal reports that, , an Inuit man fell prey to an orca entrapped by ice in Grand Suttie Bay ( Foxe Basin, Canada). A pod of orcas (likely 10-12 animals) was trapped in a polynya, and a young man visited the site in spite of advice from elders to wait until the ice was strong enough. Tw ...

KW Attack STBW
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \mathrm ...

Valdes Peninsula
The Valdes Peninsula (Spanish: ''Península Valdés'') is a peninsula into the Atlantic Ocean in the Biedma Department of north-east Chubut Province, Argentina. Around in size (not taking into account the isthmus of Carlos Ameghino which connects the peninsula to the mainland), it is an important nature reserve which was listed as a World Heritage Site by UNESCO in 1999. Geography The nearest large town is Puerto Madryn. The only town on the peninsula is the small settlement of Puerto Pirámides. There are also a number of ''estancias'', where sheep are raised. Most of the peninsula is barren land with some salt lakes. The largest of these lakes is at an elevation of about 40 m below sea level (see extremes on Earth), until recently thought to be the lowest elevation in Argentina and South America (the lowest point actually being Laguna del Carbón, Argentina). Fauna The coastline is inhabited by marine mammals, like sea lions, elephant seals and fur seals. The peninsu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orcas In Punta Norte Valdes Peninsula - Panoramio
The orca or killer whale (''Orcinus orca'') is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is the only extant species in the genus ''Orcinus'' and is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas. Orcas have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales. Orcas are apex predators, as they have no natural predators. They are highly social; some populations are composed of very stable matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liferaft
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety. Inflatable lifeboats may be equipped with auto-inflation (carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing; offshore oil platforms also have liferafts. Ship-launche ...

Yacht Racing
Yacht racing is a Sailing (sport), sailing sport involving sailing yachts and larger sailboats, as distinguished from dinghy racing, which involves open boats. It is composed of multiple yachts, in direct competition, racing around a course marked by buoys or other fixed navigational devices or racing longer distances across open water from point-to-point. It can involve a series of races with buoy racing or multiple legs when point-to-point racing. History Yachting, that is, recreational boating, is very old, as exemplified in the ancient poem Catullus 4: The yacht you see there, friends, says that she's been The fastest piece of timber ever seen; She swears that once she could have overhauled All rival boats, whether the challenge called For racing under canvas or with oars. (trans. James Michie) "Yacht" is referred to as deriving from either Norwegian ("jagt"), Middle Low German ("jaght") or from the Dutch word jacht, which means "a swift light vessel of war, commerce or p ...
