Description
The coelacanth is thought to have existed as far back as the Devonian period (around 380 million years ago), having been at its prime in the Triassic period (around 250 to 200 million years ago). It was believed to have become extinct at the end of the Cretaceous period (around 70 million years ago), along with the dinosaurs and ammonites. However, in 1938, a live coelacanth was discovered in the sea off the coast of South Africa, and it was then revealed that coelacanths existed around the Comoros Islands and other areas of the Indian Ocean side of the African continent. In 1997 a coelacanth was found in Indonesian waters, and DNA analysis showed that it was a different type to the one discovered in Africa. Coelacanths live in the sea at depths of more than 150m, in caves or in cracks between rocks. They have ten fins which they move in a complicated way to propel themselves through the water and to stay still. It has been shown that the Comoros Island coelacanth is ovoviviparous, meaning its young are incubated in eggs inside the mother’s body. However, so far only adult coelacanths have been discovered, and the details of the fish’s ecology remain unknown. Materials provided by: Aquamarine Fukushima

Description
The manta ray is the world’s largest species of ray. Larger manta rays can reach sizes of up to 8m across. Their bodies are colored black to grayish blue on the back and white on the belly, and they glide gracefully through the sea, propelling themselves by moving their large pectoral fins up and down. They inhabit tropical and subtropical oceans around the world, feeding on plankton as they swim close to the surface. They have a docile, curious temperament, making them popular with scuba divers.
