Port And Starboard (killer Whales)
Port and Starboard are a pair of adult male orcas notable for preying on great white sharks off the coast of South Africa. The duo are identified as having rare and distinct collapsed dorsal fins and they are named for the nautical terms, as Port's fin collapses left and Starboard's collapses right. Port and Starboard are part of a distinctive "flat-toothed" ecotype present around South Africa. History Port and Starboard were first reported near Lüderitz in 2009 and are often sighted travelling off the coast of Gansbaai, Port Elizabeth, Cape Town, and most notably in False Bay. Prior to 2015, it was believed that orcas entering into the False Bay area only preyed on marine mammals but reports of the pair hunting copper shark and ocean sunfish soon began. However, the duo's most notable prey have been great white sharks. The sharks began washing ashore in 2015 with nothing but their livers removed. Examination of the carcasses reveal that orcas open the sharks betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mossel Bay
Mossel Bay ( af, Mosselbaai) is a harbour town of about 99,000 people on the Southern Cape (or Garden Route) of South Africa. It is an important tourism and farming region of the Western Cape Province. Mossel Bay lies 400 kilometres east of the country's seat of parliament, Cape Town (which is also the capital city of the Western Cape), and 400 km west of Port Elizabeth, the largest city in the Eastern Cape. The older parts of the town occupy the north-facing side of the Cape St Blaize Peninsula, whilst the newer suburbs straddle the Peninsula and have spread eastwards along the sandy shore of the Bay. The town's economy relied heavily on farming, fishing and its commercial harbour (the smallest in the Transnet Port Authority's stable of South African commercial harbours), until the 1969 discovery of natural offshore gas fields led to the development of the gas-to-liquids refinery operated by PetroSA. Tourism is another driver of Mossel Bay's economy. Etymology The origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Shark
The copper shark (''Carcharhinus brachyurus''), bronze whaler, or narrowtooth shark, is a species of requiem shark, family Carcharhinidae, and the only member of its genus found mostly at temperate latitudes. It is distributed in a number of separate populations in the northeastern and southwestern Atlantic, off southern Africa, in the northwestern and eastern Pacific, and around Australia and New Zealand, with scattered reports from equatorial regions. This species can be found from brackish rivers and estuaries, to shallow bays and harbors, to offshore waters deep or more. Females are found apart from males for most of the year, and conduct seasonal migrations. A large species reaching long, the copper shark is difficult to distinguish from other large requiem sharks. It is characterized by its narrow, hook-shaped upper teeth, lack of a prominent ridge between the dorsal fins, and plain bronze coloration. Feeding mainly on cephalopods, bony fishes, and other cartilaginous fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shark Cage Diving
Shark cage diving is underwater diving or snorkeling where the observer remains inside a protective cage designed to prevent sharks from making contact with the divers. Shark cage diving is used for scientific observation, underwater cinematography, and as a tourist activity. Sharks may be attracted to the vicinity of the cage by the use of bait, in a procedure known as ''chumming'', which has attracted some controversy as it is claimed to potentially alter the natural behaviour of sharks in the vicinity of swimmers. Similar cages are also used purely as a protective measure for divers working in waters where potentially dangerous shark species are known to be present. In this application the shark-proof cage may be used as a refuge, or as a diving stage during descent and ascent, particularly during staged decompression where the divers may be vulnerable while constrained to a specific depth in mid-water for several minutes. In other applications a mobile cage may be carried by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attraction
A tourist attraction is a place of interest that tourists visit, typically for its inherent or an exhibited natural or cultural value, historical significance, natural or built beauty, offering leisure and amusement. Types Places of natural beauty such as beaches, tropical island resorts, national parks, mountains, deserts and forests, are examples of traditional tourist attractions which people may visit. Cultural tourist attractions can include historical places, sites of significant historic event, monuments, ancient temples, zoos, aquaria, museums and art galleries, botanical gardens, buildings and structures (such as forts, castles, libraries, former prisons, skyscrapers, bridges), theme parks and carnivals, living history museums, public art (sculptures, statues, murals), ethnic enclave communities, historic trains and cultural events.

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Commercial Fishing
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is also known as industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. In order to adapt to declining fish populations and increased demand, many commercial fishing operations have reduced the sustainability of their harvest by fishing further down the food chain. This raises concern for fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing. Commercial fishermen harvest a wide variety of animals. However, a very small number of species support the majority of the world ...

Cape Fur Seal
The brown fur seal (''Arctocephalus pusillus''), also known as the Cape fur seal, South African fur seal and Australian fur seal, is a species of fur seal. Description The brown fur seal is the largest and most robust member of the fur seals. It has a large and broad head with a pointed snout that may be flat or turned up slightly. They have external ear flaps (pinnae) and their whiskers (vibrissae) are long, and may extend backward past the pinnae, especially in adult males. The fore flippers are covered with sparse hair over about three-quarters of their length. The hind flippers are short relative to the large body, with short, fleshy tips on the digits. The size and weight of the brown fur seal depends on the subspecies. The Southern African subspecies is on average slightly larger than the Australian subspecies. Males of the African subspecies (''A. p. pusillus'') are in length on average and weigh . Females are smaller, averaging in length and typically weighing .King, ...

Pearly Beach
Pearly Beach is a village in Overberg District Municipality in the Western Cape Province of South Africa. An area where the southern right whale (''Eubalaena australis'') comes to calve and mate along its migratory route (June – October). These whales can be seen with their young all along the coastline with Walker Bay just a short distance away. The area is home to the threatened African oystercatcher which can be seen on the rocky coasts, beaches and at lagoons eating limpets and mussels. It is close to Bantamsklip which was a proposed site of a nuclear power station. However, Thyspunt in the Eastern Cape seems to be the most likely location. Geography Not far from Pearly Beach is Dyers Island, a breeding colony for jackass penguins. Not far from Dyers Island is Geyser Island, a breeding ground for seals. As the area around these islands teems with an abundance of sea life, it has become a notorious feeding ground for the great white shark which frequents its waters in la ...

Broadnose Sevengill Shark
The broadnose sevengill shark (''Notorynchus cepedianus'') is the only extant member of the genus ''Notorynchus'', in the family Hexanchidae. It is recognizable because of its seven gill slits, while most shark species have five gill slits, with the exception of the members of the order Hexanchiformes and the sixgill sawshark. This shark has a large, thick body, with a broad head and blunt snout. The top jaw has jagged, cusped teeth and the bottom jaw has comb-shaped teeth. Its single dorsal fin is set far back along the spine towards the caudal fin, and is behind the pelvic fins. In this shark the upper caudal fin is much longer than the lower, and is slightly notched near the tip. Like many sharks, this sevengill is counter-shaded. Its dorsal surface is silver-gray to brown in order to blend with the dark water and substrate when viewed from above. In counter to this, its ventral surface is very pale, blending with the sunlit water when viewed from below. The body and fins are c ...
