Their coloring is made to camouflage themselves from both above and below with metallic blue on top and shimmering silver-white on the bottom. Their bodies are torpedo shaped and built for speed and endurance while hunting for food, or being hunted (National Geographic). bluefin Tuna are prey only to some marine life such as, some whale, shark, and marine mammal species. With highly migratory species like bluefin tuna, management is complicated because these species migrate thousands of miles across oceans and international borders and are fished by many nations.
Adult sea turtles can weigh from 150-1000 pounds. Depending on the type of sea turtle, they can live from 50 to 80 years in the wild. They live all over the world with some preferring the tropical waters and others prefer to be where it is cooler. Threats to sea turtles today include the harvesting of their eggs for human consumption, entanglement and entrapment in fishing gear, ingestion of litter, and coastal development. Sea turtles mature at around age 30.
Killer whales can be found in all oceans of the world. They are the most numerous in the Arctic Ocean and the Antarctic. However, their distribution is limited by seasonal pack ice. Habitat. The main living environment for killer whales is open oceans but they can also be found in coastal waters as well.
Megalodon had the most powerful bite force of any creature that has ever lived! In 2008, The US and Australian palaeontologists both used the latest technology to see how powerful the bite of this magnificent shark was. A modern Great White Shark has about 1.8 tons of bite force. This led them to finding out that the Megalodon had a bite between 10.8 and 18.2 tons! This would mean they could easily crush a prehistoric whale’s skull as easily as we would eat through a banana!

Life in the Great Barrier Reef Some of the most unique and beautiful creatures in the world can be found in the Great Barrier Reef. Around thirty species of whales, dolphins and porpoises have been recorded in the Great Barrier Reef, including the Indo-Pacific humpback dolphin, and the humpback whale. Over 1,500 fish species live on the reef, including the clownfish, red bass, red-throat emperor, and several species of snapper and coral trout. Six species of sea turtles including the green sea turtle, leatherback sea turtle, hawksbill turtle, loggerhead sea turtle, flat back
Every square mile of the ocean surface off the North East coast of the U.S. has more than 46,000 pieces of plastic. Tons of marine mammals are affected yearly because of plastic in oceans including, sea turtles, seals, and sea lions. Sea turtles mistake plastic bags for jellyfish and die from internal blockages and, seals and sea lions starve after being muzzled by six-pack rings or entangled by nets. The facts are devastating we are heavily dependent of plastic and the problem with that is most of the world doesn’t dispose of it appropriately. Plastic disposal in our oceans is becoming a fast problem that needs to be addressed by every individual on the planet.
They are caught in nets through trawl and long-line fishing. Dynamite fishing blows up their food sources. They are deprived of nesting sites when sandy areas are converted into beachside condominiums, and their eggs are harvested indiscriminately, leaving few to hatch and replace the current population. The decrease in egg production of green turtles has ranged from 65% to 90% in different parts of Southeast Asia between 1930 and 1993. The region, in fact, is considered the world’s greatest consumer of turtle eggs.
This barbaric practice is known as shark finning and has been on the increase over the past few years. The main causes for shark finning are: 1) Shark fins are used for the famous Asian delicacy known as shark fin soup. The fins are minced and mixed with spices to produce this well-known dish. People from all over the world visit largely to Asia just to try this soup. 2) Fishermen locally sell shark fins in markets, as their livelihoods depend on this.
