It is believed that sea lions are capable to detect humans by smell over a long distance of hundreds of meters away. The sea lions use their sensitive vibrissae to explore objects on land and in the water. They seek out physical touch with other sea lions and form groups and lye with each other on land.
They rank number one on the scale of largest predatory fish and can grow to lengths of 23 feet and up to 2,400 pounds. Despite having developed a fearsome reputation, they are less common than other shark species. Not much is known on their population size, but it is believed their numbers are decreasing because of hunting and habitat loss. Great white sharks are typically solitary creatures and only come together to mate.
Both the humpback whales and the blue whales are extremely vocal mammals, their beautiful and mysterious songs travel great distances across the ocean; the blue whale, both the Humpback and Blue whales are apart of the class of baleen whale; while, the humpback whale population isn’t having trouble maintaining its numbers, the blue whales, whom, had previously been plagued by poachers, causing them long-term damage to their population. Both the Humpback Whales and the Blue Whales produce truly unique songs and vocalizations, that create sound waves for miles around. There are theories that the vocalizations are a form of inter-species communication between the intelligent mammals. Only male Humpback Whales sing, and the song is usually heard during the winter mating season, bringing scientists to the assumption that it might be used as a mating call to attract females. Humpback whales may sing for over 24 hours, nonstop.
They live in these types of oceans, because if it was a colder climate they would die from hypothermia and soon the species would become extinct. These sharks like to stay in schools up to 100 in numbers. The reason they stick together is there is more protection in numbers and they can kill bigger prey like big great white sharks. Next Hammerhead sharks gets there name for its flat shaped head and some people think it is useless to the shark. With their special heads, they have 360 degree vision!
Manatee - Florida manatee Introduction: The Florida manatee (Trichechus manatus) is a marine mammal which is also known as “West Indian manatee” or North American manatee. Manatees are occasionally called sea cows as they are similar to cows on land. Manatees belong to the family Trichechidae. This manatee is the largest, fully aquatic surviving member of the aquatic mammal “order Sirenia”. The lifespan of the manatee is 50-60 years in the wild.
They can also weigh up to 2 tons and have a lifespan of about 25 years. They are found mostly on the Hawaiian coastlines. The Manta Rays feed on small fish, crustaceans, and microscopic plankton particles. Fun fact: Manta Rays are related to stingrays and sharks families. Manta Rays are also known as the bird of the sea, because they flap like birds.
In the eyes of society and the public, sharks are viewed as ruthless killers Millions upon millions are killed every year, and fear is a major contributor. The reality is that sharks are very complex creatures, and should be treated as such. They are an intricate part of the ocean’s ecosystem and the ecosystem would be completely thrown off without them. We need to realize that these creatures are invaluable, and that we must conserve these animals. If we do not realize this reality, we could lose sharks forever.
However, when the whales are put into tanks they experience many more dangerous medical conditions. “Killer whales are known for their impressive dorsal fin, which in males can reach 1-1.8m tall. But, in captivity, they collapse”(Warley). In Seaworld most of the whales have collapsed fins that are turned over and are no longer straight. In the wild only one percent of dorsal fin collapse happens among whales.
The film Blackfish by Gabriela Cowperthwaite employs rhetorical strategies to convey the alarming misfortune that orca whales experience in captivity. The film follows the appalling story of the bull orca whale Tilikum and the three human fatalities he is responsible for. Ms. Cowperthwaite uses interviews with dismayed former trainers and whale experts as a vehicle to explore the gap between the conglomerate SeaWorld’s public image and its palpable reality. The wild orcas that researchers describe as highly socialized, gentle animals are juxtaposed with the creatures portrayed in footage from SeaWorld’s marine parks. The latter are abused, confined to dark cages, and live in small concrete pools that are nothing in comparison to the one
