Dive beneath the waves and experience the ocean through the eyes of a turtle, seal and shark.
The deep sea is rife with competition and conflict. Deep sea biodiversity relies on the scattered organisms interacting in order to survive, whether they’re working together in symbiosis, scavenging, being predated, or parasitising a host animal. But there is one ecological interaction that does more than any other to influence organisms to change and diversify, and thus plays an important role in the success of deep sea communities. The limited resources mean only a small number of niches can exist. Thus, there is greater competition between different species trying to fill the same niches. This explains why the deep sea has so much competition, for animals must share the ecosystem with other competing species all trying to consume the same limited resources.

As it floats on the surface of the ocean, the Man O’ War looks beautiful and harmless but packs a killer sting with its deadly tentacles.
The Portuguese man o’ war, also known as the man-of-war, bluebottle, or floating terror is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean. It is considered to be the same species as the Pacific man o’ war, which is found mainly in the Pacific Ocean.
A family of saddleback clownfish have found an excellent home, however, they need a place to lay their eggs.
Amphiprion polymnus, also known as the saddleback clownfish or yellowfin anemonefish, is a black and white species of anemonefish with a distinctive saddle. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone.

From underwater hunts to dancing whales, here are some of our all-time favourite ocean moments.
Hawaii is home to the largest hard-shelled sea turtles in the world.
Hawaiian green sea turtles, or honu, are native to Hawaii. They are the largest hard–shelled sea turtle in the world, reaching lengths of four feet and weights over 300 pounds. Out of the seven types of sea turtle, the Hawaiian green sea turtle is the most common turtle in Hawaii.
Away from the burning glare of the Caribbean sun live some unusual animals. Cuba is home to the Hutia, a small dog sized rodent as well as plenty of marauding crabs!
Hutias are moderately large cavy-like rodents of the family Capromyidae that inhabit the Caribbean Islands. Twenty species of hutia have been identified but at least a third are extinct.
Gecarcinus ruricola is a species of terrestrial crab. It is the most terrestrial of the Caribbean land crabs, and is found from western Cuba across the Antilles as far east as Barbados. Common names for G. ruricola include the purple land crab, black land crab, red land crab, and zombie crab.
For years, one of South Africa’s great tourist attractions has been the opportunity to see great white sharks up close. But barely any great white sharks have been spotted off the coast of Cape Town, South Africa for two years now – where there used to be hundreds.
This sea-diving lizard only has 30 minutes to search for food before his muscles seize up.
The marine iguana, also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a species of iguana found only on the Galápagos Islands. Unique among modern lizards, it is a marine reptile that has the ability to forage in the sea for algae, which makes up almost all of its diet.
The Galápagos Islands is a volcanic archipelago in the Pacific Ocean. It’s considered one of the world’s foremost destinations for wildlife-viewing. A province of Ecuador, it lies about 1,000km off its coast. Its isolated terrain shelters a diversity of plant and animal species, many found nowhere else. Charles Darwin visited in 1835, and his observation of Galápagos’ species later inspired his theory of evolution.
