The top 200 meters of ocean are known as the epipelagic, or sunlight, zone because the sun's light is able to penetrate into this zone. ]]> 2017-03-03 07:21:30 UTC https://padlet.com/17j_amoy/udb2hdo1pj7/wish/157542072 17j_amoy https://padlet.com/17j_amoy/udb2hdo1pj7/wish/157542663 Killer whales inhabit all oceans of the world. Next to humans and perhaps the brown rat (Rattus norvegicus), killer whales are the most widely distributed mammal. In addition to being found in colder water, killer whales also have been seen in warm water areas such as Florida, Hawaii, Australia, the Galapagos Islands, the Bahamas, and the Gulf of Mexico and more temperate waters such as New Zealand and South Africa. Such sightings are infrequent, but they do demonstrate the killer whales' ability to venture into tropical waters.]]> 2017-03-03 07:27:25 UTC https://padlet.com/17j_amoy/udb2hdo1pj7/wish/157542663 17j_amoy https://padlet.com/17j_amoy/udb2hdo1pj7/wish/157543828 Orcas are Nekton animals which means they are part of a collection of marine and freshwater organisms that can swim freely and are generally independent of currents,ranging in size from microscopic organisms to whales.]]> 2017-03-03 07:37:49 UTC https://padlet.com/17j_amoy/udb2hdo1pj7/wish/157543828 17j_amoy https://padlet.com/17j_amoy/udb2hdo1pj7/wish/157544701 Orcas are carnivores and diets on fish, seals, turtles, and birds.

2. Orcas have developed eyesight; an amazing echolocation system; and they vocalise with clicking sounds, whistles and pulses; and when underwater, their heart beats 30 beats per minute, while at the water surface, the heart beats 60 beats per minute.
3. An orca’s diet varies among different groups, which can consist of 30 fish species, some whales and 32 aquatic mammal species, including seals, dolphins and porpoises, and they can consume 227 kilograms (500 pounds) of food per day.
4. Each orca has a unique saddle patch design (the area around the dorsal fin) and a triangular dorsal fin, and the male’s is larger than the female, and can be as tall as 1.8 metres (5.9 feet).
5. Orcas are also known as ‘killer whales’, ‘orca whales’ and ‘blackfish’, and are often misunderstood to be ferocious killers, but, in reality they rarely attack humans, although some of those kept in captivity have caused human fatalities.
