The hammerhead sharks are excellent predators that belong to the order Carcharhiniformes and family Sphyrnidae. Members of this family of sharks have unique head structures that extends to form a hammer-shaped (T-Shaped) cephalofoil that have different functions including sensing, water maneuvering, and manipulating prey. This family has two genera; Eusphyra and Sphyrna. Hammerheads are distant relatives of the mid-Tertiary period carcharhinid sharks. Today, species of the hammerhead include Eusphyra blochii (Winghead shark), Sphyrna corona (Scalloped bonnethead), Sphyrna couardi (Whitefin hammerhead), Sphyrna gilberti (Carolina hammerhead), Sphyrna lewini (Scalloped hammerhead), Sphyrna media (Scoophead), Sphyrna mokarran (Great hammerhead), …show more content…
Most of the members are gray in color and have some greenish tint with white bellies. This color balance enables the sharks to perfectly blend with the ocean since a prey viewing from the bottom will not see it sneaking in for a meal. The cephalofoil laterally project outwards thus giving the shark the hammerhead shape and, as a sensory organ, ability to easily notice electric field created by prey or threat from miles away. All the hammerhead sharks have excessively small mouths compared to other sharks located at the bottom of the cephalofoil with serrated triangular teeth. Hammerheads have wide-set eyes on the outer edges of the hammer adapted to give a wider and better visual range compared to other sharks. The eyes can rotate for a 360 degrees vision and one eye can see below while the other sees up simultaneously, however, the positioning of the eyes create a blind spot in front of the nose. The nostrils are expanded further enhancing their ability to follow scent and locate prey. Other features include two extra tall dorsal fins of different sizes. Most hammerheads have a lifespan of between 25 and 35 years though observations are currently indicating that more and more of this shark family live longer than 35
Sharks rely on their fins to swim and allow water to
Hammerheads are a unique species of shark with a distinct physical appearance which makes them a great research project
70 common limpets were identified in the 40m bracket identified as the littoral zone, between 0m to 40m. The common limpet employs a range of adaptations to survive the abiotic and biotic conditions associated with the littoral zone. Firstly, the limpet uses a structural adaptation to overcome the harsh wave action in the tidal zone, by using their radula to grip on to imperfections in the rock. Furthermore, they employ a behavioural adaptation of grinding their shells down into the rock, to further ensure they are not swept away by the tide. Additionally, the limpet utilises a behavioural adaptation regarding its tough shell and powerful radula, to defend against predators.
The three spined stickleback fish has many unique traits. some of the most notable structural adaptive traits of this specie are the three spines and body armor. The three spines are sharp and located on the back forward of the dorsal fin. The lateral bony plates are located on each side of the body. These structural armors projecting from the back and pelvis can simultaneously flare out when the fish feels threatened as a defense against predatory vertebrates making it difficult for predators to swallow them.
Hammerhead sharks prefer to hunt at night time. When the oceans are warmer, Sharks usually hunt in groups to save energy and they can get more food. A few sharks can hunt and bring back food for others. Hammerheads don’t always attack everything they see that they can eat. Not eaten what harms them can make sharks save
THE GREAT LAKES The great lakes are comprised of 5 different fresh water lakes, Superior, Huron, Michigan, Ontario, and Erie. The lakes are situated along the US-Canadian border, touching Ontario in Canada and Michigan, Minnesota, Wisconsin, Illinois, Ohio Pennsylvania, Indiana and New York in the United States. Roughly 34 million people in Canada and the United States live in the great lakes basin, and also 35 000 plants and animals, over 170 of those being fish, inhabit the great lakes (Zimmermann). This significantly large water body holds an estimate of 6 quadrillion gallons of water.
Its flaxen eyes are usually the only part of the cuttlefish that pokes above the ocean bottom. At nightfall, the cuttlefish comes out to feed on small shrimp and fish. Two long fins haunch the sides of the striped pyjama squid body and the arms of its two tentacles have small suckers, each having a toothed horny rim. The lower side of its body is veiled in small glands that let out slime when The Striped Pyjama Squid is under attack by predators, quickly scarring off or terminating any predators from harming it by any means. It can also quickly change color to a dark purple-brown, making it easier to screen itself against corals and rocks near the bottom of the
The northern snakehead preys on zooplankton, smaller fish, fish larvae, crustaceans, frogs, insects, small reptiles, and even small mammals and birds. In the areas in which the northern snakehead has invaded, native populations are having gradual decreases because of the northern snakehead’s unextinguishable appetite. The most notable features of the northern snakehead fish are its snake-like characteristics. The fish has a long cylindrical body with the blotchy coloration and patterns of a snake.
Loggerheads are also prey for a large number of both terrestrial and marine
Nonetheless, our group observed specific locations in the skull that over time, changed among species. The following methodology will include how to observe or examine the different locations that were relevant to the study. By looking for the widest part in the back of the skull the location of the maximum skull breath can be identified. The degree of postorbital constriction can be recognized by observing the space behind the brow/supraorbital ridge. The zygomatic flare can be examined by evaluating how wide is the zygomatic bone.
During the observation scientists observe sharks and records their motions and thinking. Scientists use acoustic monitors to track their every movement such as their depth in the ocean, living temperature space, and location. They Identified Hammer sharks using two types of pop up satellite archival tags. Scientist wanted to know where they live, feed, and go. Scientists were able to follow a Hammerhead shark, and saw all of these things that they were curious about.
Hammerhead sharks rarely attack humans. Only 17 atacked have happened in the last 450 years but none of the attacks were serious enough to be fatal. The animal i'm going to be comparing the hammerhead to is a bottlenose dolphin. The dolphin doesn't chew its food it just goes down the throat like a snakes. I think that the dolphin would be a better survival than the hammerhead because they live in a lot more places than the hammerhead.
I am going to tell you all about whale sharks’ adaptations. First, whale sharks diet is that they do not attack They do eat shrimp. Second, there habitat is in the warmer areas. Some have been spotted in the cooler warters. Last there habits they are solitary creatures.
Its body is slim and egg-shaped shaped in cross section. The corner of the mouth spread out past the eye, this is why it’s called the largemouth bass. (Bailey, et al., 2004; Boschung, et al., 2004) Young largemouth basses eats zooplankton and insects that is in the marine.
Their eyes on the side of their heads help them to look all around without fully turning their body. With the wider view of all around they can counter attack their predators attach. When the hammerhead shark goes to attack anything it will charge at its
