The mahi-mahi or common dolphinfish[1] (Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical and subtropical waters worldwide. It is one of only two members of the Coryphaenidae family, the other being the pompano dolphinfish. It is also known as the dolphin,[2][3] which causes confusion with the more widely-known marine mammals called dolphins. Mahi-mahi means very strong in Hawaiian. In other languages the fish is known as lampuga, lampuka, rakingo, calitos, maverikos or dorado.
Pink dolphins eat crabs, catfish, small river fish and even small turtles. As crabs and turtles have to be catch mainly at the bottom of the river, pink dolphins spend a lot of time while swimming looking at the bottom of the river for food. They are able to move their head up to 180 degrees, which is a great help for hunting in shallow waters and floodplains. Hunting fish require
The members of a pod hunt together, attacking even very large prey and then sharing it. The pod members always protect the young, the sick and the injured. Orcas grow to be about 27-33 feet long, and weigh more than 8,000-12,000 pounds. The male orca is larger than the female. They are the largest member of the dolphin family.
The juvenile Rainbow Parrotfish generally spends its time in "mangrove sanctuaries", areas where the roots of a mangrove tree grow into the ocean and serve as a safe haven for small fish. Unfortunately, due to human interference and other factors, these mangrove populations are waning as well. This is opening these sanctuaries to predators and not allowing the juvenile fish that called them home to survive. The solution essentially narrows itself down to one goal, save the mangroves and, as a result, save the Rainbow Parrotfish. The question that I am asking is: "How much, in detail, does saving the mangroves help the Rainbow Parrotfish?

The tweet appears on the official Twitter account of Surf Life Saving Western Australia (@SLSWA). It even includes details of the shark’s size, breed and approximate location – like this: Tweet of a shark’s location Dr Rory McCauley of the WA Department of Fisheries said the battery in the device could last up to 10 years, giving researchers an unprecedented look into shark movement
The plants release dissolved oxygen and harbor fish and shellfish (Franklin, 2001). They swim in large schools close to the water’s surface. Throughout the spring, the schools of younger, smaller fish are found in estuaries, such as the Chesapeake Bay, and the larger, older fish are found further offshore and up north. Menhaden also play an important role to the fisheries, especially along the Atlantic and Gulf coasts. Humans don’t actually
Olive flounder, Paralichthys olivaceus Introduction: The Olive flounder or Bastard halibut (Paralichthys olivaceus) is left-side flatfish that belongs to the family Paralicthydae. Depending on locations, the species may be referred as the Japanese flatfish or Korean flatfish. Distribution and habitats: The Olive Flounder is native to the subtropical/temperate western pacific from the Sea of Okhotsk off south eastern Russia, along Japanese shores to the South China Sea. Being demersal, the adults live in waters 100 meters or more deep, and migrate into shallow waters in the spring to spawn. Olive flounder can be found lying in the bottom sediment with only their eyes exposed.
Olive Ridleys get their name from the coloring of their heart-shaped shell, which starts out gray but becomes olive green once the turtles are adult. Hatchlings are dark gray with a pale yolk scar, but appear all black when wet. Carapace length ranges from 37 to 50 mm. Olive Ridleys are omnivorous, meaning that they consume a varied diet from both plant and animal sources. Distribution Although Olive Ridleys spend time in the open ocean, they also forage in coastal waters and estuaries.Olive Ridley turtles are found only in warmer waters, including the southern Atlantic, Pacific and Indian oceans.
Following Captain Cook Charles Darwin has been doing a closer study of Marine life (he was also known for the Theory of Evolution). Darwin went on the HMS Beagle. He went on in 1831 he spent five years collecting and studying sea life (he came back in 1836). All of Darwin’s marine organisms that he found when he was on the HMS Beagle have been sent to a British Museum for cataloguing. When Darwin was on the HMS Beagle it helped him make theories of natural selection and evolution.
