(They live in the tropical rain forests of Central and South America.) It is also said that “they are especially vulnerable to the effects of forest fragmentation.” (2) Another reason that some Spider Monkeys are endangered is because of the threat of hunters. People of the same habitat as Spider Monkeys often hunt them for food. A big reason why they are so attractive as food to others is because of their huge size, with them being able to reach 24 pounds in weight as a mature male. Although the Spider Monkeys are suffering every day because of their loss of habitat and the threat of their hunters.
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.
Most jelly fish are dangerous as they sting other creatures, when touched by one of their tentacles. Clown fish are immune to stings thus why Marlin wasn’t affected. 14. Compare Dory, Bruce and Nemo, which is the best adapted for speed and why? Bruce is best adapted for speed, as he is a shark and needs to be fast to catch and hunt down his prey.
They have no natural enemies except man and power boats which are responsible for most manatee deaths- (in 1990, 218 manatees or 12 % of the total population were killed by boats), though the red tide (toxins released from the bloom of dinoflagellates) of 1982 and1996 killed over 15% of the population. It is suspected that environmental pollutions create disease vulnerability in marine mammals with manatees being no exception. An example is when 10,000 seals died in 1988 in Denmark and Sweden from viruses related to canine distemper. High concentrations of PCB’s were detected in necropsies of these seals, presumably from the water and fish they ate. Other threats include accidental
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!
Alligators and they get trapped within the hydrilla. Limpkins, because their primary food source, apple snails, are dying out in the Wakulla Springs ecosystem. Apple Snails and they are being battled because the hydrilla halts the snails as they ascend to the surface, so they drown. Some of the methods that have been used and that have failed are using dip nets, booms, hand pulling and mechanical harvesters The method that is being used now is putting herbicide within the spring. “Hydrilla was imported
Dr Carl Meyer from Hawaii Institute of Marine Biology stated that mass levels of shark culling “runs the risk of ecosystem-level cascade effects where a general lack of sharks results in boom or bust in populations of species further down the food chain”. Furthermore when nets are used to trap sharks, often animals such as dolphins, turtles, whales and dugongs become trapped in them. Turtles are one of the most endangered species as a whole and are just innocent bystanders in this war between humans and sharks. We need to be careful of not affecting other animals in this quest to reduce shark numbers in the name of nothing. Sharks can already be caught legally by commercial and recreational fishers so any cull would be largely
Many different kinds of fish live in the reefs as their haven for feeding, reproduction, and safety from predators. Without an ecosystem to live in, these fish species will become extinct. Ten percent of the world's reefs have been completely destroyed. Coral reef destruction is the worst, over 70% have been destroyed and only 5% can be said to be in good condition. What has happened to destroy so many reefs?
ABSTRACT Coral reefs ecosystems have drastically changed over the past 40 years. The main reasons for the decline of coral reefs is due to weather and temperature changes, too much pollution, boats, and overfishing. As a result, coral reefs are considered an endangered species. Over 50% of the people in the Florida Keys rely on the coral reefs in one way or another. Many don’t realize that they provide humans with a source of income and more importantly, life for a wide diversity of marine animals.
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.
