Although evidence has shown that there is a recent change in the increase of the cownose ray that has caused a large boom, it's Well known that the cownose ray is a predator of shellfish when the water becomes warm. The marine systems caused by the removal of sharks remain misleading, due to the significant declines in large coastal sharks in the northwest Atlantic Ocean, which caused dramatic increases in abundances of smaller elasmobranchs (referred to as “Macropredators”) over the predation release. The large coastal sharks decline allegedly led to an order of large scale increase in the population of Cownose rays. Thereby the ever-increasing feeding of the cownose ray has led to the concerns for the shellfish populations along the U.S.…
Tursiops australis, otherwise known as the Burrunan dolphin was recognized in 2011 south-east of Australia by Kate Charlton-Robb and colleagues. The Burrunan dolphin is a type of bottlenose dolphin. There are actually two new distinct species of Tursiops dolphins found in Australia that are under controversy. At one time, all Tursiops dolphins were recognized as belonging to T. truncates. However T. australis, T. truncates and T. aduncus are all distinctly recognized species found around Australia.…

The species interaction in the Florida Everglades had gone through difficult times, but the awareness of the needs of this area have made it possible to help build a healthy living species. The fresh water that is currently coming into the Florida Bay from the Everglades is creating perfect conditions for beds of turtle grass and algae formation that are the foundation for animal life. Sea turtles and manatees eat the grass, and worms, clams, and other mollusks eat the algae formations and microscopic…
After reading about manatees and elephants,I realize that they have many similarities. But you can still identify them through their differences.…
(1985) examined mortality patterns of manatees in Florida. To better understand these mortality patterns in Florida, four areas along the coastline were analyzed. A carcass salvage program was initiated in 1974 to document causes of death in manatees in Florida (O’Shea et al. 1985). Carcasses were recorded from these different areas and the cause of death was determined. Two categories of mortality showing greatest increases were boat collisions and death of dependent calves (Garrett et al. 1994). Winter plays a major role in the survival of manatees that live in Florida. The years 1977 and 1981 showed the highest rate of manatee mortality that have occurred in the winter months in Florida (O’Shea et al.…
Imagine you are in a boat right off the shores of Greece. You happen to look up and out of the corner of your eye you see something. As your gaze adjusts, you notice it's a killer whale, being torn away from his home. A large net encloses in in, attached to a large ship. Now, imagine you are sitting in the stands at SeaWorld, surrounded by hundreds of people, people waiting so eagerly to lay eyes on this year’s rendition of “Shamu”. When you look into the cement “pool”, you see him. You see the majestic, beautiful, free, wild animal now in captivity. Only, this time, he looks tired, old, neglected, abused, and lifeless. This is exactly what SeaWorld is doing to killer whales. They take these wild animals out of their natural habitat and force them into captivity.…
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.…
Manatees are one of the luckiest and unluckiest mammals in the world. However, their predators are very strong and powerful. Killer whales, sharks, and alligators are a few of their predators, but their biggest predator is man. Man cause 39% of deaths. Nets and boat propellers are the main reason of their deaths. Since manatees are injured by man, there are laws that save them from extinction.…
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…
The killer whale, also known as an orca, is known to be the largest dolphin. Killer whales population is decreasing every year, mostly due to them being held in captivity. Whales in the wild tend to live longer and reproduce more often to healthier offspring, which is why we should leave them there.…
There is a disagreement between the passage and the lecture concerning possible explanations of sea cow's extinction, one kind of marine animal. The reading passage represents 3 theories about the extinction. However, the lecture casts doubt on it, and gives contradicting evidence.…
The reading and the listening both discuss about the distinction about the Steller’s sea cow which a huge marine mammal lived in the waters around Bering Island off the coast of Siberia in 1768. The reading supports there probobal theories. However, the listening disputes all the reading’s opinion.…
If there are no existing protections, you have the option to launch a petition. In order to launch a petition, you will need substantial data showing manatee endangerment and get an endorsement from FWC. You will need significant manatee data to compel support from FWC. Therefore, you want to make sure you document any danger to manatees, humans, and/or property. You and your neighbors also need to document manatee sightings and vessel sightings, and if there are close calls between the two. Once you believe you have collected sufficient information, you can send it to Scott.Calleson@myfwc.com. You are also welcomed to send Save the Manatee Club this information for us to keep on file and utilize it when there is a speed zone…
