The Galápagos penguin (Spheniscus mendiculus) is a penguin endemic to the Galápagos Islands of Ecuador. It is the only penguin found north of the equator. [4] Most inhabit Fernandina Island and the west coast of Isabela Island. [5] The cool waters of the Humboldt and Cromwell Currents allow it to survive
Humboldt penguins are medium-sized penguins, growing to 56–70 cm (22–28 in) long and a weight of 2.9 to 6 kg (6.4 to 13.2 lb). [10] [11] [12] The sex of the Humboldt penguin cannot be recognised via differences in plumage, as they are monomorphic. The male is heavier and larger than the females. [13]
The surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.
The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
The African penguin (Spheniscus demersus), also known as Cape penguin or South African penguin, is a species of penguin confined to southern African waters. It is the only penguin found in the Old World. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine habitat. Adults ...
Gentoo penguins can reach a length of 70 to 90 cm (28 to 35 in), [19] [20] making them the third-largest species of penguin after the emperor penguin and the king penguin. Males have a maximum weight around 8.5 kg (19 lb) just before moulting and a minimum weight of about 4.9 kg (11 lb) just before mating.
Water can be broken down into its constituent hydrogen and oxygen by metabolic or abiotic processes, and later recombined to become water again. While the water cycle is itself a biogeochemical cycle, flow of water over and beneath the Earth is a key component of the cycling of other biogeochemicals. [8]
These two species live on the seafloor from relatively shallow water to depths of 3,000 m (9,800 ft), and can grow to around 2 m (6.6 ft) long weighing up to 100 kg (220 lb), living up to 45 years. [ 23 ] [ 27 ] The Antarctic toothfish lives close to the Antarctic mainland, whereas the Patagonian toothfish lives in the relatively warmer ...
