I think Killer Whales should not be in captivity because, of the injures they can get in their tanks, how they get stressed out and they are better in the wild. The first reason why I think should not be in captivity is of what happens in their tank. The first piece of evidence from the PETA practical “Aquariums and Marine Parks” is that since the tanks for the orcas are usually small for them, they get insane because of the echolocation they use. This makes me think that since their fin sometimes curves, that they would get injured while swimming. In addition, this might make the whale die faster than what they are supposed to live to.
They also feed on crabs and clams. The quantity of fish consumed by sea lions depends on their size as well as the abundance of fish in their habitats. Sea lions may use their sensitive whiskers to locate food. They will generally hunt close to the shore as long as their food is sufficient otherwise they move to deeper water looking for food while they become vulnerable to their predators of Killer Sharks and Whales. Sea Lion swallow their food without chewing or tear it into chunks using their sharp teeth.
Hammerhead sharks are found in ecosystems in temperate and tropical oceans. 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.
a. N= (100*100)/36= 277.77 ~ 288 individuals in population b. Yes, the yellow tang is a species of saltwater fish. Even though they are the most common fish in areas like Hawaii and Japan, they live in shallow reefs and are commonly taken to be exotic pets to be put in aquariums which could affect their population
These sea anemones often adorn the shells of the hermit crabs, and fends off small predators with its stinging cells. In return, the sea anemones obtain food scraps from the crab. The relationship between these two species are so important, that when hermit crabs switch shells, they will coax and remove the anemone from the old shell to their new one (“Crabs” 1093). In addition to sea anemone, many other types of epifauna also adorn the shells of hermit crabs, and it was hypothesized that the type of shell affects the biodiversity of the fauna. Two species of the hermit crab, the Pagurus bernhardus and the Pagurus pubescens in Arctic waters, were studied and the biodiversity of the epifauna on the shells of these hermit crabs were explored.
This evidence helps explain why the shark didn’t come back for more. But it also shows an example of a tiger sharks hunting strategy, which indicates that this shark was doing more than warning her, but wanted her as its next meal. Concluding that although not all sharks are out to kill humans, doesn’t mean there isn’t, which adds on to my belief that the fear of sharks that humans have are very much
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.
The quality of the water you fish also makes the difference in your bass fishing tactics. In muddy water, for example, the bass uses their sonar to locate food. So choose lures that vibrate well and maybe make noise. In clear water, however, the basses are very cautious and suspicious of something unusual. So you need bright lines and lures that look a lot like local food sources.
In this paper I will be talking to you about how we can save turtles from these big threats to Loggerhead turtles and about what these threats are doing to the Loggerhead Sea Turtles. One of the main threats to Loggerhead Sea turtles is fishermen. Loggerhead Sea Turtles
Web. 01 Feb. 2017. This article is full of reasons why orcas should not be a seaworld. It gives examples about how it is damaging to their health to be there. This article was written to compare and contrast the health of an orca living in the wild, and an orca at seaworld.
By creating experimental beach scenarios, negative and standard, Karpanty, et al, increased and decreased the amount of surface eggs to compare the availability and sufficiency to refuel Red Knots in the Delaware Bay area. They were able to determine that horseshoe crab eggs were sufficient and that Red Knots were not excluded when aggressive shorebirds also foraged on the experimental beach areas. The feeding times were mainly during the day and until high tide. It was observed that Red Knots foraged in high-density areas and along the wrack line, where horseshoe crab eggs were visible and easily accessible. Once that area was depleted, the Red Knots would move on to other horseshoe crab nesting areas.
Lionfish were most likely introduced through the pet trade like the python. Although there is another theory that they were introduced by floating lionfish nest, it is rather unlikely considering that the nearest native range for them is the South pacific and the Indian Ocean around Australia and India. Lionfish were first reported off of Florida 's Atlantic Coast near Dania Beach in 1985. The lionfish 's habitat ranges greatly from 1 foot of water to 300 feet. It usually thrives in reefs but it is also easily found in hard bottom areas, mangroves, seagrass flats, and shipwrecks.
Loggerhead turtles are species generalists. Loggerheads compete with other carnivorous predators whose diets overlaps with theirs. For example, juvenile loggerheads and Kemp’s ridleys in waters around Long Island have substantial diet overlap. Interspecific competition also occurs for nest sites for beaches shared with other sea turtles species; however, this problem was likely greater in the past before modern turtle population declines. The diet of loggerheads includes many species that are harvested by humans and consequently decreases in food resources can result in sublethal effects in the form of decreased growth rates and reproductive output (Bjorndal 2003).
In addition, because nesting females generally return to their natal beaches and there is a low gene flow between nesting assemblages, these populations that are genetically distinct are at risk for extirpation (Ehrhart et al. 2003). Additionally, the potential for loggerheads to choose suitable nest sites is limited by human activity. Sea turtles will be less likely to nest on beaches that have high human recreation or that have been altered by humans. Beaches that are near human development pose a threat to sea turtles, not just by human presence, but because artificial lights prevent hatchlings from being able to orient themselves toward the ocean (Lindsay 2003).
These fish live in the Pacific Ocean, but they are also found in the Indian Ocean, from East Africa to Micronesia, according to the International Union for Conservation of Nature (IUCN) (2012). Their homes are the coral reefs that grow along the shores. These fish are very important to the lifecycle of the coral reef. They eat excess algae in the reef, which prevents the coral from suffocating (Frost 2016). These fish are somewhat social and are usually found in pairs or in small groups (10 to 12 members) of several different surgeonfish and tang (Bradford 2016).
