Diving with turtle, stingray and jellyfish
You will hardly find a person who would not enjoy the serene sound of the sea. AirPano team enjoys diving with marine creatures, as well. Our video will show the beauty and the grace of the turtle, the jellyfish and the stingray.
Several species of turtles inhabit the sea, including the hawksbill sea turtle. This animal is easily distinguished from other sea turtles by its sharp, curving beak. This reptile lives in the waters of the Atlantic and the Indo-Pacific region, but its population is low, so the International Union for Conservation of Nature has classified it as critically endangered.
Hawksbill sea turtles spend all their lives in the sea and come out of the water only for breeding. During this period, female turtles make a long way through the ocean to get the nesting beaches. The archipelago of Gardens of the Queen (Jardines de la Reina) located in Cuba is one of these places. Hawksbills lay eggs once in two years and make 2-4 clutches containing 70-180 round eggs each being 40 mm in diameter.
Baby-turtles hatch out 60 days later. The gender of the turtles depends on the temperature: females are formed in a warmer sand. When baby-turtles are born, they have a 2.5 cm long shell and weigh no more than 24 grams. 20 years later, they grow up to 1 meter long and gain up to 80 kilos of weight.
There are more than 600 species of rays known to science. They inhabit all the seas and oceans, including the Arctic and Antarctic ones. Rays have special organs generating electric current. Some species of rays are dangerous for people as their current is strong enough to stun humans, while the Dasyatis species can even cause painful wounds.
Technically, the jellyfish is one of the two lifecycle phases of the Cnidaria. These aquatic animals have cnidocytes, specialized explosive cells that they use mainly for capturing prey and self-defence. Jellyfish, comparing to polyps which are the other body form of the Cnidaria, are moving and able for reproduction.
Its genus name, Medusa, has come from the name of Medusa in Greek mythology, alluding to her tentacled head.
Jellyfish are effective hunters, as their bodies are well suited for capturing prey. They can catch everything with their long tentacles: plankton, insect larvae, crustaceans, small fish and squids, while the poison from cnidocytes makes their prey helpless.
Jellyfish are ones of the most ancient inhabitants of the planet: they have roamed the seas for at least 500 or even 700 million years.
