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
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 buoyancy allows the cuttlefish to hover over the floor of the oceans. The siphuncle is highly modified, running on the ventral side of the shell. Although the cuttlebone is unique to the cuttlefish, it does have a minor set back. Between the depth of 200 and 600 meters the cuttlebone can implode. Because of this factor cuttlefish have adapted to the seafloor in shallow marine waters as their habitat.
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. Hatchlings are dark gray with a pale yolk scar, but appear all black when wet. Carapace length ranges from 37 to 50 mm. Olive Ridleys are omnivorous, meaning that they consume a varied diet from both plant and animal sources. Distribution Although Olive Ridleys spend time in the open ocean, they also forage in coastal waters and estuaries.Olive Ridley turtles are found only in warmer waters, including the southern Atlantic, Pacific and Indian oceans.
There are 4 types of flat bottom hull boats which include a barge, bateau, flatboat, and the gondola. The flat bottom hull is used in shallow bodies of water, so it would not be good to use in the ocean or in deep water for any type of job or activity. This boat is generally used for fishing in bays or even in lakes. The broad bow area creates a rough ride on the boat for people, this happens because since the boat has a flat bottom it is easy for waves in waters to make the boat bounce. Another type of boat is the vee bottom hull, and this is the most common out of all the boats.
The Oceanic White-Tipped Shark is a pelagic shark which means it lives close to the surface and rarely goes to the ocean floor. It is an aggressive slow moving fish that usually will find a carcass of a whale or other large marine animal and dominate the feeding frenzy. It gets its Name white-tipped shark because every fin on the shark has a white tip except the anal fin which has a black tip. They inhabit most of the Salt water of the world because they can live in cold or warm water. Excluding the occasional feeding frenzy, white tips also eat a diet that consists mostly of cephalopods.
Emperor Penguin, the warriors of nature are considered the most beautiful of all penguins, and are the largest of all penguins. The males and females are hard to distinguish as they are very similar in physical size. Adult Emperor Penguins can weigh from 50 to 100 pounds and be up to 48 inches tall. The back parts of the Emperor Penguins are black with a white front, they also feature bright splashes of yellow and orange on their breast region and their ears. Like all penguin species, emperor penguins have streamlined bodies to minimize drag while swimming, and wings that are more like stiff, flat flippers.
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
The world’s coral reefs covers only about 368,000 square miles occupying less than three tenths of one percent of the ocean’s floor. Although the ecosystem is a small one, close to one million species of fish, crabs, eels, molluscs, sponges, worms, algae, grasses and other marine life call the coral reefs their home. But the coral reefs are depleting. There are many factors that contribute to the depletion of coral reefs. They are coral mining, climate, diseases, tourism, blast fishing, farm runoff, sewage, oil and industrial pollution.
