A large carnivorous predator that is found swimming through coral reefs is the barracuda. This large fish is a widely feared species and has the features of an apex predator. It has a large mouth, a missile-like body, and spikes. They also tend to scare divers by following them, but they are just extremely territorial, trying to protect their home.…
The Snapping Turtle has a giant shell on is back that protects it from its very few predators. When the Snapping turtle is in the water it is relatively docile and doesn't go looking for trouble, but on land it is very aggressive because it's very slow.…
maenas is cannibalistic, especially in postlarval and juvenile stages (Moksnes et al., 1998). This cannibalism tends to be density dependent and self-regulates populations of C. 5 maenas (Moksnes, 2004). Mortality by means of predation by H. sanguineas serves to further thin populations. C. 5 maenas is also very efficient in selecting habitats with low risk of predation (Moksnes, 2002). H. sanguineus populations are at higher densities in rocky intertidal areas, the same refuge habitat preferred by juvenile C. maenas. In response, C. 5 maenas has shifted habitat usage to areas with reduced refuge (Jensen et al. 2002). 5 This habitat shift also creates a shift in diet in adults from primarily consuming mussels to primarily consuming red algae (Griffen et al., 2008). Reduced refuge creates risk of predation by seabirds, fish, and other predators. Dietary shifts of C. 5 maenas in the presence of H. sanguineus could reduce C. maenas populations in two ways. First, this shift in diet decreases nitrogen consumption which slows growth rates of C. 5 maenas, potentially extending the time susceptible to size dependent predation (Griffen, 2008). In the presence of H. sanguineus, C. maenas typically forages for red algae (Chondrus crispus) containing 0.4%-1.4% nitrogen with higher values in winter and lower in summer (Chopin and Floch, 1992). Otherwise, C. maenas would prey on mussels (Mytilus edulis) containing 7.7%-9.6% nitrogen with higher values in spring and lower in late…
There are many animals in the world. Some of them as small as ants and some are even bigger than elephants. These animals live throughout the world, some in the gigantic oceans, some in the coldest of Antarctica or some in the hottest of deserts. These are the classes of animals, mammals, amphibians, birds, reptiles, and insect. Reptiles are cold-blooded vertebrates. They have dry skin covered with scales or bony plates, and they usually lay eggs. Reptiles can be classified into three groups, turtles, snakes, and lizards. There are lots of species of turtles, like the sea turtle who live in the oceans. They can be identified by their long, streamlined shell and their color range of olive-green, yellow, greenish-brown, reddish-brown, or black.…
Sloths are cool and interesting animals. They are excellent climbers; in fact, they learn to climb from their parents. they also learn what food to eat by watching their mother eat. Sloths don’t really learn anything (except climbing and what to eat) from their parents because they, well, don’t really do anything. Pretty much all sloths do is eat, sleep, and hang upside down.…
There is no good evidence to point to and say there it is – an Otterman/ Kushtaka! Certainly no evidence that will convince the scientific…
My name is Jaron Pierre Jr. and i am going to be talking about the sea otter . The sea otter is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean . They live over 10-15 years . Their breeding season is during September to November , they are territorial during it . Their scientific name is Enhydra lutris . Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb) , making them the heaviest members of the weasel family , but among the smallest marine mammals . Unlike most marine mammals , the sea otter’s primary form of insulation is an exceptionally thick coat of fur , The densest in the animal kingdom . Even though they can walk on land , the sea otter lives mostly in the ocean . The sea otter…
Kemp who made the first report of seeing the turtles. They mainly in the live in the Gulf of Mexico but some baby turtles are found near the Atlantic. Most female Kemp’s Ridley’s lay their eggs on the main nesting beach of Rancho Nuevo in Mexico. Where they dig a hole lay their eggs, cover them with sand and then leave them to hatch and get to the ocean alone. Parenting made easy, huh? The Ridley’s are cold blooded amphibians and have a lifespan up to 50 years but today only 1% of the Kemp’s Ridelys survive to reach sexual maturity. This is caused by three main factors, one is that since 1970 these turtles have been taken out of their habitat and brought to Mexico and South Texas to be sold for various recreational uses. As the population of the Ridley’s decreased so did the turtles availability on the market. The second reason is loss of habitat. Everywhere you look hotels and condos are going up along shorelines taking away the nesting ground of the Ridley’s. There is only one beach, located in Mexico, which is officially protected for the Kemp’s Ridley’s greatly reducing the chances of eggs surviving anywhere other than that beach. And the last and most horrible reason for these turtle’s death and endangerment is drowning in shrimp nets. Of the few turtles that survive being hatched and manage to get by predators, 1/3 of them drown in the shrimping nets they get caught in. Between 500 and 5,000 Kemp’s Ridley’s turtles are…
. Unlike many marine animals that inhibit large open water areas, manatees often occupy narrow shaped bodies of water such as canals, rivers and creeks (Edwards et al. 2007). They are considered one of the most endangered marine mammals in US waters due to their small population and threats to their habitats (Garrott et al. 1994). Boating collisions, storms, and exposure to cold waters can increase their mortality rates. Manatees often acquire distinctive marks in the wild from natural and human-related causes. Boat inflicted injuries, fishing line entanglements, and lesions from infection and cold damage can leave permanent scars after they heal (Langtimm and Beck 2003). These mammals can also starve and die of cachexia, the wasting away of body fat from lack of food in the stomach…
The Florida manatee continues to be exposed to a lack of warm water habitats, injury due to boat strikes, and lack of access to healthy sea grasses and other food sources. Also, there are few areas for them to raise their babies.…
As you walk into Marineland, and you see all the posters of the cute sea lions, dolphins, orcas etc. You think to yourself, “Wow, this park is the best! Everything looks so clean, and the animals in the poster look like they’re treated well, right?” Wrong. In reality, most of the animals are kept in dirty, tiny cages. How do these people expect for the animals to somehow survive in these inhumane conditions?…
A manatee is a big marine mammal with a roundish egg kind of head, flippers and a flat tail. Manatees are also called sea cows. They call them sea cows because they're slow, lolling nature; and they get eaten by other sea creatures sharks and crocodiles. Did you know that cows can swim well they can so sea cows and cows are mostly the same except manatees live underwater cows well they live on land manatees can’t breathe underwater but they can still hold their breath underwater. The natural diet of a manatee; manatees love sea grasses that makes manatees herbivores. Manatees live in slow moving rivers they consume freshwater vegetation. Manatees also likes algae according to National Geographic, a manatee will most likely eat tenth of his/her…
Large sharks such as tiger and bull sharks, both of which do enter bays, estuaries and river mouths, may pose a threat to Florida manatees in those waters. Other potential predators include American alligators and crocodiles, the latter wide-ranging along the South Florida coast. Orcas, which have been implicated in attacks on dugongs in the Indian Ocean, aren’t particularly common in manatee range. Calves are likely more vulnerable than adults to such…
Manatees are a highly talked about animal in our society today due to the fact that they love to reside in shallow waters along the coast of Florida, thus exposing the top of their bodies to possibly getting hit by boaters. This has sparked a heated debate as to what actions should and shouldn't be taken to protect the West Indian Manatee.…
If you see anyone exhibiting an activity of harassment towards manatees, you can report manatee harassment by calling the FWC Wildlife Alert number 1-888-404-FWCC (3922). In addition, be sure to document if there is repeated harassment, and your…
