In the past year researchers have discovered that the Homarus americanus consume fresh food as their primary food source which includes clams, fish, mussels, crabs, sea urchins, starfish, marine worms, shrimp, plants such as eel-grass and algae, carrion just like the blue crab, and sometimes other lobsters! The Homarus americanus have two claws that are used for acquiring food and consuming the aliment. One of the claws is used to crush shells and animals with hardened outsides such as clams and muscles to obtain some of the meat inside. The other claw is referred to as the feeder claw or pincher which is more maneuverable and transfers the aliment to its mouth. The Homarus americanis consume food by positioning its mouth close to its prey which is how lobsters with omitted appendages consume their victims! When the lobsters fresh catch of the day has to be prepared the lobsters unique digestive system really helps. The digestive system consists of three stomachs, which are within the cephalothorax . The for-gut (first stomach) moils the aliment into minuscule specimens with grinding teeth. The second stomach (mid-gut) has glands to digest the fragment of food.

A female lobster can mate just after she sheds her outer shell. When she is ready to molt, the female lobster approaches a male's den and giving off wafts pheromone in his direction. Unlike other females, whose pheromone may attract dozens of arbitrary males, the female chooses the male. She usually pursues the bulkiest male in the area and he stands outside his burrow, releasing her scent in a stream of urine from openings just below her antennae. He responds by fanning the water with his swimmerets, permeating his apartment with her pheromone. He emerges from his den with his claws raised aggressively. The female crab responds with a a couple nudges or by turning away. Then the female raises her claws and places them on his head to let him know she is ready to mate. They enter the den, and a few hours to several days later, the female molts. Then the male, who remains amalgamated-shelled, inserts his first pair of swimmerets, and transfers his DNA into a receptacle in the female's body. She stays in the safety of the burrow for about a week until her new shell hardens. After mating, the female stores the sperm for many months. When she is ready to lay her eggs, she turns onto her back and cups her tail. As many as 10,000 to 20,000 eggs are pressured out of her ovaries. They are fertilized as they pass through the sperm receptacle. A substance plasters the eggs to the bottom of the female's tail.She will carry the eggs for 9 to 11

    Wallace’s whole purpose was to get his audience to stop and think about what is really going on with the food we eat. Wallace calls animal-cruelty-and-eating issue not just complex but uncomfortable (Wallace 68). Wallace’s primary is claim is this; if animals feel the pain that we think they do when they are killed to be consumes, what makes that okay in our minds? Wallace highlights the moment when you put the lobster in the boiling water and you can hear their claws rattling and clanking as the lobster tries to push off (Wallace 69). Again, another effective use of the pathos…

    Consider The Lobster Essay

    Wallace explains how lobsters are boiled alive for our pleasure “each lobster is supposed to be alive when you put it in the kettle.” (p.56). He also talks about how the lobster senses that his “end” is near “The lobster will sometimes try to cling to the container’s sides or even to hook it’s claws over the kettle’s rim like a person trying to keep from going over the edge of a roof… Even if you cover the kettle and turn away, you can usually hear the cover rattling and clanking as the lobster tries to push it off.” (p.62). I think Wallace shows us EXACTLY why we shouldn’t eat other animals. Why eat another living being knowing you will cause him suffering? Why are they always slaughtered in an inhumane way?…

    Male octopodes reproduce by using a special arm called a hectocotylus and inserts it into its partner’s mantle cavity.

    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.…

    He uses pathos to draw the audience emotions to actually think about what these lobsters are going through while being cooked, this rhetorical strategy is incredibly convincing in this case to the readers. He states actions the lobsters take as they are being thrown into a cooking pot, ‘The lobster will sometimes cling to the container’s sides or even to hook its claws over the kettle’s rim like a person trying to keep from going over the edge of a roof.(.. )you can usually hear the cover rattling and clanking as the lobster tries to push it off. Or the creature’s claws scraping the sides of the kettle as it thrashes around.” This metaphor he uses paints a horrific image for the audience as they read it, he makes a point that some people often mistakenly boil lobsters in salt water instead of tap water and by doing so that smothers then instantly to death. All of what he explaining is set in place to make the reader really think about the whole cooking process that these creatures are put through.…
