Sea Jellyfish Adaptations

Decent Essays
Have you ever wondered what adaptations allow deep-sea creatures to survive in extreme environments? There is no simple answer due to the fact that all creatures adapt to their environment in different ways. Although sea creatures live together in the same ocean, the condition in different areas varies. The different characteristics of these four sea creatures make them unique, therefore giving them various ways to adapt to extreme oceanic environments in order to survive. Despite living in different locations of the ocean, zombie worms, giant squids, yeti crabs, and deep-sea jellyfish all share one common trait: they must adapt to their environment to survive.
A recently explored area of the ocean near Antarctica in the Southern Pacific has

In contrast to most sea creatures, these unique critters “live on the skeletons of whales, which drift down to the ocean floor” (Ennis). Because zombie worms are attached to the whale bones, they must use them to contribute to their diet. These ocean animals “lack a mouth and gut, [so] the worms drill into the bones [to] extract the stored nutrients” (Ennis). Without this adaptation, zombie worms would starve and die. Zombie worms also have an additional way to digest food through their bodies; they “[use] a process called symbiosis, in which the worms depend on the internal bacteria to digest the fats and oils extracted from their whale-bone diet” (Ennis). Just like the yeti crab, zombie worms do not have any known predators. Zombie worms’ unique adaptations allow them to live their life attached to sunken whale bones on the ocean floor without having to leave the comfort of their …show more content…
The deep-sea jellyfish has an especially unique way to survive in the ocean “in depths up to 12,000 feet” (Deep-Sea). Unlike the giant squid, deep-sea jellyfish do not obtain the ability to attack and slice their prey. Instead, they use an alternative method. “The moment a jellyfish feels threatened by a predator, it flashes bright blue lights in a circular pattern that also turn on and off, which is known as a bioluminescent ‘burglar alarm.’ The jellyfish’s striking display might scare the predator” (Jonssen). There are also other results in addition to the jellyfish’s light scaring predators away. “These flashing lights might attract an even bigger predator that could then eat the fish that was about to eat the jellyfish” (Jonssen). Jellyfish are different from other animals in the sea, because “[they] are carnivorous, feeding mostly on a variety of zooplankton, comb jellies, and occasionally other jellyfish; larger species, however, are capable of capturing and devouring large crustaceans and other marine organisms” (Deep-Sea). If deep-sea jellyfish did not have these qualities, they would not be able to

    The shark is still alive when it is thrown back into the ocean. The poor creature is forced to sink down to the bottom of the ocean, all while being unable to move, and is now an open target for smaller fish to come and feast on. The great white sharks are very much endanger when it comes to shark finning, with their fins fetching the highest prices. Great whites are also in danger of getting tangled in fishing nets along with shark nets, which are designed to protect swimmers from sharks. The main issue, with shark nets, is that they are protecting swimmers from a rare occurrence, all while suffocating and harming the shark.…

    Not only that, but sharks also have small pores in their snout called campulae which sense impulses emitted by other creatures. Some things that would tempt a shark’s senses would be low-frequency sounds, as of a struggling fish. Another would be a splashing sound, like of a flailing animal. Always remember to take off shiny and reflective jewelry, because a shark may mistake it for fish scales. Once a shark has found its victim, it stalks it before going in for the kill.…

    This is unlike the human digestion in the mouth, as humans do a lot of physical digestion by chewing their food. Additionally, humans also use their saliva and tongue to help start the process of breaking down the food. Sharks however do not do this process instead the buccal cavity which secretes mucus to aid in swallowing. Moreover, both sharks and humans have many differences and similarities when talking about the stomach. To begin, both species use the stomach to help digest and break down food.…

    Terrestrial Humanoids: These homo sapien like creatures were a mistake. They’ve evolved to have four arms in a span of such a short amount of time because of radiation poisoning. These four arms allow these new humans to hunt their main source of nutrition, the Fuzzy Hamster or Cutus Pufiratus and the ever elusive and tasty Butter-Roach. Tentacled Aqua Humanoids: These deformed humanoids are the unfortunate result of devolution and deformity. Living underwater and completely disconnected from one another by a lack of any communication (at least known to us), they swim around the ocean floor occasionally coming to the surface to feed on their only form of nutrition besides water, aqua…

    Hodges provides multiple images and graphics throughout the article that allow readers to get a better viewpoint of the open water experience and to gain more knowledge of the sharks as a whole. The up close image of the diver within 10 feet of the Tiger shark (86) allows readers to see how close Hodges and his fellow divers got to be to the sharks. It makes readers think to themselves, “Just how dangerous could these sharks be if they are allowing divers to be this close to them without considering them prey.” Divers just need to know the behaviors of the sharks they are working with, such as that these Tiger sharks do not see you as prey because you are at their level with them - and because Tigers rely on surprise attacks with them in close eye of the divers they lose their element of attack. A multiple page fold out Sharks: Lords of the Sea is provided within the article between pages 96 and 97, filled with background and facts on multiple shaks. This provides readers with a stronger overall sharl knowledge as it presents facts on the each shark, such as diet, location, and build.…

    Shark finning is a process of removing the fins from a live Shark and casting the animal back into the ocean, leaving them to die several days later (Fairclough, Caty. "Shark Finning: Sharks Turned Prey"). The rest of the Shark is then left because Shark meat is of low economic value and takes up too much space for the fisher to take them back. In addition, Shark meat also contains urea, which turns to ammonia once the Shark has died and contaminates other fish. This is done so the fins can be sold on the black market, fins are sold for about $650 per kilogram (about 2.2 lbs) so they are in high demand ("Shark Truth."…

    An alligator gets into a fight with another gator or even a human he will use the Death roll to overpower his opponent. This act is as much an eating technique than a killing technique. The alligator will sometimes wedge the prey between two pieces of stone and then roll with the prey in their mouth to secure bits of meat. American alligators are also known to modify their environment by creating burrows. These are created using both snout and tail and are used for shelter and hibernation during freezing temperatures.…

    While their niche in the ocean is to kill and eat, its a very important niche. Great white sharks and pretty much all sharks go for the weaker and sick prey so they won't have to work hard. By doing that they leave the healthy and efficient fish to reproduce and pass their healthy and efficient genes. Sharks not only maintain other species but also serves as indicators of how healthy a part of the ocean is. If there are no sharks in an ecosystem then there would be no regulators to kill bad fish and overpopulation among other species would occur.…
