Mubarak Goth
Mubarak Goth or Mubarak Village ( ur, ) is a fishing village in Kiamari Town in Karachi, Sindh, Pakistan. It is located along the shore of Arabian Sea in Keamari District. Demography The village is 30 km away from city center with a population of more than 10,000 people. The most of the people in this village are Baloch. Fishing village Karachi's second largest fisherman locality of Mubarak Village- does not have basic facilities including jetty, gas, health and education, despite the fact that it existed even before the independence of Pakistan.

Wakesurfing
Wakesurfing is a water sport in which a rider trails behind a boat, riding the boat's wake without being directly pulled by the boat. After getting up on the wake, typically by use of a tow rope, the wakesurfers will drop the rope, and ride the steep face below the wave's peak in a fashion reminiscent of surfing. Wakesurfers generally use special boards, designed specifically for wakes. History The origins of wakesurfing are somewhat disputed with multiple people and companies claiming to be at the genesis of the sport. Some claims have set the dates for the origins of boat-surfing or wake-surfing as far back as the 1920s. However, no credible evidence of this is available. Footage and print media from the 1950s and 1960s show ocean surfers actively riding surfboards behind motor boats. By the mid 60's numerous surfboard manufacturers laid claims to building wake specific boards. The practice of riding surfboards behind boats continued through the 70s and 80s with the boards be ...

Mahi-mahi
The mahi-mahi () or common dolphinfish (''Coryphaena hippurus'') is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. Also widely called dorado (not to be confused with '' Salminus brasiliensis'', a fresh water fish) and dolphin, it is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii and the Indian Ocean. Nomenclature The name mahi-mahi comes from the Hawaiian language and means "very strong", through the process of reduplication. However in Māori, a sister language of Hawaiian, "mahimahi" almost exclusively refers to the verb meaning to have sex. By chance in Persian, mahi (ماهی) means fish, but the word mahi in Hawaiian has nothing to do with the Persian language. Though the species is also referred to as the common dolphinfish, the use of "dolphin" can be misleading as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobia
The cobia (''Rachycentron canadum'') is a species of carangiform marine fish, the only extant representative of the genus ''Rachycentron'' and the family Rachycentridae. Other common names include black kingfish, black salmon, ling, lemonfish, crabeater, prodigal son, codfish and black bonito.

Yellow-bellied Sea Snake
The yellow-bellied sea snake (''Hydrophis platurus'') is a venomous species of snake from the subfamily Hydrophiinae (the sea snakes) found in tropical oceanic waters around the world except for the Atlantic Ocean. For many years, it was placed in the monotypic genus ''Pelamis'', but recent molecular evidence indicates it lies within the genus ''Hydrophis''. Taxonomy In 1766, Linnaeus published the original description of the yellow-bellied sea snake, naming it ''Anguis platura'' (''Anguis'' meaning snake). In 1803, François Marie Daudin created the new genus ''Pelamis'' and assigned this species to it, referring to it as ''Pelamis platuros''. In 1842, Gray described what he thought was a new species and called it ''Pelamis ornata'' (subsequently ''P. ornata'' became a synonym of ''P. platura''). The commonly used genus name ''Pelamis'' is derived from the Ancient Greek word for "tunny fish", which presumably refers to the habitat or what Daudin thought they ate. The specifi ...

Killer Whale
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baleen Whale
Baleen whales ( systematic name Mysticeti), also known as whalebone whales, are a parvorder of carnivorous marine mammals of the infraorder Cetacea ( whales, dolphins and porpoises) which use keratinaceous baleen plates (or "whalebone") in their mouths to sieve planktonic creatures from the water. Mysticeti comprises the families Balaenidae ( right and bowhead whales), Balaenopteridae (rorquals and the gray whale), and Cetotheriidae (the pygmy right whale). There are currently 16 species of baleen whales. While cetaceans were historically thought to have descended from mesonychids, molecular evidence instead supports them as a clade of even-toed ungulates (Artiodactyla). Baleen whales split from toothed whales (Odontoceti) around 34 million years ago. Baleen whales range in size from the and pygmy right whale to the and blue whale, the largest known animal to have ever existed. They are sexually dimorphic. Baleen whales can have streamlined or large bodies, depend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Whale
The blue whale (''Balaenoptera musculus'') is a marine mammal and a baleen whale. Reaching a maximum confirmed length of and weighing up to , it is the largest animal known to have ever existed. The blue whale's long and slender body can be of various shades of greyish-blue dorsally and somewhat lighter underneath. Four subspecies are recognized: ''B. m. musculus'' in the North Atlantic and North Pacific, ''B. m. intermedia'' in the Southern Ocean, ''B. m. brevicauda'' (the pygmy blue whale) in the Indian Ocean and South Pacific Ocean, ''B. m. indica'' in the Northern Indian Ocean. There is also a population in the waters off Chile that may constitute a fifth subspecies. In general, blue whale populations migrate between their summer feeding areas near the poles and their winter breeding grounds near the tropics. There is also evidence of year-round residencies, and partial or age/sex-based migration. Blue whales are filter feeders; their diet consists almost exclusively ...

Jellyfish
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are comm ...

2004 Indian Ocean Earthquake And Tsunami
An earthquake and a tsunami, known as the Boxing Day Tsunami and, by the scientific community, the Sumatra–Andaman earthquake, occurred at 07:58:53 local time ( UTC+7) on 26 December 2004, with an epicentre off the west coast of northern Sumatra, Indonesia. It was an undersea megathrust earthquake that registered a magnitude of 9.1–9.3 , reaching a Mercalli intensity up to IX in certain areas. The earthquake was caused by a rupture along the fault between the Burma Plate and the Indian Plate. A series of massive tsunami waves grew up to high once heading inland, after being created by the underwater seismic activity offshore. Communities along the surrounding coasts of the Indian Ocean were devastated, and the tsunamis killed an estimated 227,898 people in 14 countries, making it one of the deadliest natural disasters in recorded history. The direct results caused major disruptions to living conditions and commerce in coastal provinces of surrounded countries, incl ...
