THE GREEN SEA TURTLE Sea turtles are large, air-breathing reptiles that inhabit tropical and subtropical seas throughout the world. Seven distinct species of sea turtles grace our oceans today. Upon first sight of the Green Sea Turtle it may appear to come off as any other turtle. The truth is that these turtles are magnificent beautiful creatures that spend most of their lives exploring endlessly through our massive ocean. These reptiles have the ability to do incredible things.
The wall of a jellyfish body is very fragile. Their bodies are much different then that of most animals. They have no brain, no respiratory system, and no circulatory system. The average length of a jellyfish tentacle is one to ten meters long. The tentacles of a jellyfish in some cases can grow to a massive length of 100 feet!
Some manta rays live in a particular location while others travel from places to places. Manta rays are filter feeders. They consume a large quantity of zooplankton by filter seawater through their mouths while swimming. And usually many manta rays swim in lines with their mouths open to filter more zooplankton. Manta rays are huge in size so only sharks and killer whales can harm them and eat them.
The green color comes from the algae or grasses that they eat. The Green Sea Turtle spends almost its entire life in the water, it returns to land only in order to lay its eggs. The majority of the time it spends in the water it is submerged. One of the amazing ways that this animal has been able to adapt to its environment is its ability to remain submerged for long periods of time. While being submerged it is either spending its time in rigorous activity or in long periods of sleep.
Of the many species alive today, some are highly endangered.  Turtles are ectotherms—their internal temperature varies according to the ambient environment, commonly called cold-blooded. However, because of their high metabolic rate, leatherback sea turtles have a body temperature that is noticeably higher than that of the surrounding water. Turtles are classified as amniotes, along with other reptiles (including birds) and mammals. Like other amniotes, turtles breathe air and do not lay eggs underwater, although many species live in or around water.
Besides global warming there is another problem with this beautiful structure and that is the result of several local natural and human factors such as over fishing. Silt from deforested lands and pollution from crowded coastlines choke them, and overuse and destroy coral reefs. There are many other factors which if they are not stopped it will destroy all coral reefs. Corals are animals, not plants; sunlight is the key to their survival. They need it to power the millions of microscopic algae, called zooxanthellae, that live in their tissues.
Many don’t realize that they provide humans with a source of income and more importantly, life for a wide diversity of marine animals. By 2050, there is a possibility that the coral reefs might die out if their habitats continue to worsen (Trinh, 2012). This paper reviews information on what coral reefs are, the importance of coral reefs, information on the Florida Keys and Caribbean, explains the problems they face, and how coral reefs can be helped. INTRODUCTION Coral reefs, one of the most diverse ecosystems, provide life to a variety of marine animals (Coral Reef Protection, 2012). Reefs have been called the “rainforests of the sea,” because they provide homes to numerous marine animals (Trinh, 2012).
• HOW THEY ARE FORMED: A coral polyp is an invertebrate animal. However, coral polyps do have skeletons, which they make with limestone. Thousands of these tiny skeletons combine to become the structure of a reef. Calcium is extracted from the seawater by the polyps and combined with carbon to make limestone (calcium carbonate). Over thousands of years, the coral
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.
What I find peculiar about the bull shark is its ability to live in both marine habitats and freshwater habitats. In general, being able to survive in both habitats is very uncommon for sharks. Aquatic organisms rely heavily on a process called osmoregulation that allows them to achieve homeostasis of water content within their body. Without going into too much detail on the specifics of osmosis and osmotic pressure, this process allows the organism to keep their internal fluids from getting too diluted or too concentrated. So you may be asking yourself, how does this apply to the bull shark?
