Transcript of American Alligator (Alligator mississippiens)
SCIN 130 Power Point presentation by Serena L. Sobolewski

Introduction: The organism that I have chosen for this assignment is an animal, of the crocodilian family, called the American Alligator. The scientific name is Alligator mississipiens In Spanish it is is called El Legarto, meaning the lizard. The habitat preferred by the American Alligator is fresh water swamps, marshes, rivers, lakes, and occasionally smaller bodies of water, such as man-made retention ponds. The alligator range is from the southern Virginia/North Carolina border, along the Atlantic coast to Florida and along the Gulf of Mexico as far west as the Rio Grande in Texas.
I chose this organism because

These creatures lurk near in or near the edge of the water waiting for prey to swim or walk by. the alligators can lunge up to five feet to rapidly grab hold of its next meal. Once an alligator captures something, it will hold it in its mouth and drag it underwater to drown it. It must then get back above water to swallow it -- otherwise, the alligator 's stomach and lungs would fill with water. Using its incredibly powerful jaws an alligator will break bones or crush shells to create a chunk of flesh that can fit down its throat. Then it will raise its head, open the palatal valve and swallow the piece whole. An alligator can digest anything it swallows -- muscle, bone, cartilage, etc. are all digested …show more content…
Although small prey is swallowed whole, large prey are subdued and dismembered. This maneuver is dramatically termed the `death roll '. The death roll is an example of a behavioral strategy referred to more generally as rotational feeding.
Body-rolling inertial feeding or rotational feeding is used by elongate vertebrates that lack specialized cutting dentition (The inability to cut food into smaller portions requires the American alligator to use mechanisms to remove manageable pieces from prey that are too large to consume whole. 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. If the water they live in dries out, alligators will swim or walk to other bodies of water, sometimes even taking shelter in swimming pools. Abandoned burrows are used by other animals for

    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.…

    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.…

    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.…

    Orca Dolphins Essay

    Orcas have figured out that when a ray is flipped upside down, the ray goes into a state of shock, or paralysis, called tonic immobilization. Then the orcas can kill it without any fear of the ray fighting back. Another method that orcas use when hunting rays is that one orca might daintily lure the ray out of its hiding place, then another orca swoops in and delivers a fatal bite to the ray’s head. The third way is one orca will pin the ray down to the ocean floor upside down, and another plucks the stinger out of the ray with its teeth, then kills the ray (“three-amazing-orca-hunting-strategies”). All of these hunting methods are always with more than one orca attacking, which relates to one of the reasons why orcas hunt and live in pods.…

    They have remarkably developed teeth with two rounded teeth at the front of the upper jaw while numerous crushing teeth are found in lower jaw.
