These reptiles have the ability to do incredible things. The Green Sea Turtle is one of seven species and happens to be the largest member of the Cheioniidae family. According to www.turtles.org/hawgrnd.htm , scientists assume that post-hatchlings, pelagic-stage Green Sea Turtles are omnivorous, but there are no data on diet from this age class. Young Green Sea Turtles have a diet of jellyfish and other invertebrates. Adults tend to eat sea grass and algae.
The sting of a moon jellyfish is harmless and has a very mild feeling. Moon jellyfish live in large groups and are most commonly found on the coasts of the Atlantic, Pacific, and Indian oceans. The largest type of jellyfish is the lion’s mane jellyfish, which also belongs to the class Scyphozoa. The lion’s mane’s tentacles can reach to a length of over 100 feet making it the longest animal in the world. It can also range from a few inches to eight feet in diameter.
This helps with buoyancy and balance. When they breathe-only through their nostrils, they can exchange 90% of the air in their lungs with each breath, compared to a human who only exchanges about 10% of their air. They may need to breathe every 30 seconds during strenuous activity but can stay submerged for up to 20 minutes. Their muscles lack the density of myoglobin (muscle hemoglobin) that is typical of other diving mammals. This trait contributes to their relatively short (8-15 minute) and shallow (10-20 feet) dives compared to seals and dolphins, however they do swim like dolphins and seals in a dorsoventral fashion as opposed to side to
Manta rays are huge in size so only sharks and killer whales can harm them and eat them. However, many manta rays survived from the attack of sharks or whales. It is amazing that manta can heal the wound of shark’s bite and after a few years their broken fins can eventually grow back. However, the population of manta ray is declining. According to some statistic, the catch of manta ray has increased in Indonesia since 2005.
They need to feed their chicks and the colonies are often a long way from the fishing grounds. Each chick needs about 42 kg of food from each parent.The entire breeding population of emperor penguins may consume as much as 1,500,000,000 kg (1,500,000 metric tons) of krill, 115,000,000 (115,000 metric tons) of fishes and 3,500,000 (3,500 metric tons) of squid each year. Method Of Collecting And Eating Food Penguins feed at sea. Most feeding occurs within 15.3 to 18.3 m (50-60 ft.) of the surface.
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
Turtles are reptiles of the order Chelonii[2] or Testudines characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield. [3] Turtle may refer to the chelonian order as a whole (American English) or to fresh-water and sea-dwelling chelonians (British English). [4] The order Chelonii or Testudines includes both extant (living) and extinct species. The earliest known turtles date from 220 million years ago,[5] making turtles one of the oldest reptile groups and a more ancient group than lizards, snakes or crocodiles. Of the many species alive today, some are highly endangered.
The plastron and other under parts have a faded yellow ochre appearance. Hatchling loggerheads (like all young sea turtles) are cute and engaging animals. Extensive ground and aerial surveys as recently as 1990 put loggerhead nest estimates at 50,000-70,000 per year in the Southeast U.S. This number represents approximately 35-40% of the world population of loggerhead turtles. The hawksbill sea turtle (Eretmochelys imbricata) is a critically endangered sea turtle belonging to the family Cheloniidae.
Whaling in the Faroe Islands is not as cruel as many think - It is conducted in a humane manner with regards to both the population and the pain of the whales. One of the most common arguments offered by anti-whaling activists is the claim that the "whale population" is endangered, and that the Faroese are hunting them to extinction. First, there are more than seventy-five species of whales, so one must know the specific species before they can make any kind of intelligent argument. Second, the pilot whale (the whale hunted by the Faroese) is actually thriving in the North Atlantic and in most of the world. Furthermore, not a single whale species has ever been hunted to extinction, and the pilot whale population has not diminished at all from being hunted for over one-thousand years.
Olive Ridley sea turtles, Lepidochelys olivacea are small, hard-shelled marine turtles, one of the two species of the genus Lepidochelys, and a member of the Family Cheloniidae. The adult turtle has a carapace of length 60 to 70 cm. They rarely weigh over 50 kg. It has hear-shaped carapace. Olive Ridleys get their name from the coloring of their heart-shaped shell, which starts out gray but becomes olive green once the turtles are adult.
