Examples of endangered marine species
I'm sure everyone has visited an aquarium where you saw a lot of different animals. Whether it was at a school trip or just for fun, that doesn't matter. What matters is that these animals are endangered, and you might have been glimpsing them for the last time.

I'm sure everyone has visited an aquarium where you saw a lot of different animals. Whether it was at a school trip or just for fun, that doesn't matter. What matters is that these animals are endangered, and you might have been glimpsing them for the last time.
First Endangered Marine Species : Pink Dolphin
Pacific humpback dolphins are struggling to survive due to pollution, overfishing, excessive boat traffic and habitat loss. These dolphins are thought to be an unique sub-species of the chinese white dolphin. They are known for their bright pink colour.
These dolphins are also found in small populations off the coast of China, Singapore, Thailand and Vietnam. Dolphins are Cetaceans(mammals) meaning they have hair (though you might have a hard time finding it), bear live young and suckle them, are warm-blooded, and breathe air with lungs. They are highly endangered.
Second Endangered Marine Species: Sea Turtles
Marine turtles are long-lived, slow growing reptiles with low population. They are found throughout the tropical waters of the world, and many populations are in decline following intensive direct harvests of adults and eggs, incidental captures in varied coastal and pelagic fisheries, habitat loss or alteration, and oceanic pollution.
In Southeast Asia their numbers have declined due to increased pressures from human population expansion, and unregulated and overexploited harvests of eggs and adults.
Third Endangered Marine Species: Dugongs
Dugongs are large grey mammals which spend their entire lives in the sea. They are three metres long and they weigh 400 kilograms. They have nostrils near the top of their snouts. Dugongs swim by moving their broad spade-like tail in an up and down motion, and by use of their two flippers.
Dugongs' only hairs are the bristles near the mouth. Dugong are subject to a range of human threats, including entanglement in shark, mesh and gill nets, loss and degradation of important habitat such as seagrass meadows, and collisions with boats (also known as boat strikes).
Forth Endangered Marine Species: Coral Reefs
Coral reefs are massive structures made of limestone deposited by living things. Although thousands of species inhabit coral reefs, only a fraction produce the limestone that builds the reef.
The most important reef-building organisms are the corals. Although corals are often mistaken for a rock or a plant, it is actually composed of tiny, fragile animals called coral polyps.
The coral reefs existing today began growing as early as 50 million years ago. The coral reefs are threatened by several things which are water pollution, sedimentation, coastal development, Destructive Fishing Practice, coral mining, careless tourism, Ocean Warming and Coral Bleaching and ozone Depletion.
Fifth Endangered Marine Species: The Blue Whale
The Blue Whale is believed to be the largest animal ever to have existed. The Blue Whale's body can be various shades of bluish - grey dorsally and somewhat lighter underneath. Blue Whales were abundant in nearly all oceans until the beginning of the twentieth century. For over 40 years they were hunted almost to extinction by whalers until protected by the international community in 1966.
