Sharks are enormous mammals that live within the deep ocean waters all over the world. There are several different sharks in many parts of the world depending on temperature, seasons, food and more. Every shark is unique in their own way and every species is unique as well. Although humans view them as vicious creatures that are out to harm us while we are at the beach on a sunny Sunday, these creatures are just trying to live like any other animal in this planet. They each have different defense mechanisms, and physical features that all them to live and continue reproducing. For example, sharks have different type of dorsal fins, teeth, hunting strategies, movement patters, and mating techniques. All of this is important to the survival …show more content…
They have a wide variety of preys, however they prefer to prey on stingrays (Strong, 1990). Their denticles are used to prey on the stingrays in order to facilitate their feeding. These denticles are used more as teeth than fish scales of how sharp and dangerous they are. They also prey on invertebrates, small boney fish, and other sharks as well. They travel throughout the coastal semi ocean (Carlson, 2002). Tiger sharks and Hammerhead Sharks have distinct tooth morphology apart from other body features. Their tooth morphology differentiates their eating habits and patters, as well as distinguishing each shark from each other. Although the teeth of these two sharks are similar, their eating habits and patters do differentiate. The Tiger Shark has sharp and serrated teeth. This means that that when looking at a shark tooth, their tooth is not only a triangular shape but along the sides they have some sort of ridges. This is the serrated area where its little pointy edges across the tooth in order for them to be more useful in the sense of being sharp to catch their prey (National Geographic, n.d.). Their teeth are about 10 millimeters in length in order for them to be efficient for preying (Ebert, n.d.). Tiger Shark’s teeth are able to crack shell of animals such as crabs. This demonstrates how strong and sharp they are that they can go through hard surfaces. Also, as previously mentioned, they are able to eat other sharks as well. This demonstrates that they are strong teeth and able to support a lot of pressure such as when devouring another shark (National Geopgraphic,
Sharks rely on their fins to swim and allow water to
Their coloring provides a camouflage to the ocean floor allowing them to hide from their enemies, killer whales and sometimes scuba divers. Hammerheads mostly stay along continental shelves and coastlines, but on occasion they are found in the deep ocean cruising near the surface. Sharks have adapted to living in a wide range of aquatic habitats at various temperatures. While some species inhabit shallow, coastal regions, others live in deep waters, on the ocean floor and in the open ocean. Hammerhead Sharks are exotic and cannot be kept as a house pet, but they can be found in many aquariums.
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 are carnivore because they eat meat much as fish species. They will eat fish to regain their energy because they use most of it swimming. They also use energy by using their sense of smell that allows them to detect blood. When a shark reaches a point when they can’t use any more energy, they will go deep into the ocean and stay there. Their preys won’t spot them as easily when they are deep in the ocean.
Another method is we can repel them by striking the surface of water with our hand. Stewart went to the marine reserves of Coco’s Island, Costa Rica and the Galapagos Islands, Ecuador. Another species of sharks called hammer heads are the sea creatures that have two more senses than other people. Hammer heads are one of the most misunderstood species. They are incredibly shy organisms.
This beautiful looking fish packs a punch: The fish has venomous spines that deliver an extreme pain that can last for days. In extreme cases, the venom can even cause paralysis. The LIonfish is an apex predator on the reefs using its fins to coral small fish and anything it can fit into it’s mouth into a corner before it strikes quickly swallowing it whole. The lionfish feeds on an array of over 50 species including ecologically and economically important species. ("Lionfish Biology Fact
According to Charles Peterson, a marine sciences biology and ecology professor at the University of North Carolina, between 1970 to 2005; there was a 97 percent decrease in the scalloped hammerhead and tiger sharks along the east coast. During that time, 14 different prey species’ populations increased. Moreover, overfishing is a contribution in the declining numbers of sharks. People are more open to trying different foods
These vibrissae are as sensitive as human fingers and allow the manatee to feel its surroundings in a better manner. When feeding the manatee uses its split upper lip to help gather and manipulate food allowing them to easily grasp their food. The manatee only has hind molars that move to the front row slowly as teeth fall out , these molars are efficient for grinding down plants and other forms of vegetation that the manatee feeds on. While the manatee mainly lives in warmer waters they have a thick layer of fat covering their bodies in order to insulate themselves from the cold.
There’s a place in the world that they feed bull sharks, because when they do for the sharks they do not have to hunt. When they are full they do not hurt people. Bull sharks are just looking for food, and when they are fed they are really cool animals. Bull sharks are cool animals, here are some facts. They are fond all around the world, and they are found near shore lines.
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.
Hammerhead Sharks protect themselves by swimming away from predators and attacking their predators. The Carnivores can outswim a sea creature and they will lose where the Hammerhead went. Even if another species can go as fast as a hammerhead shark, they will still escape. The hammerhead tries to stay away from where their predator was chasing them for some time and then returns if they need to. While swimming, they have very strong senses that can tell when something is getting near them.
Tigers are likely to go extinct. After years of saving the tigers, what danger could still exist for these creatures? In the article, “6 Reasons We Should Still Worry About Tigers Survival of The Big Cats in The Wild is Far from Guaranteed,” written by John R. Platt, he informs the reader that even though the number of tigers living in the wild has improved, humans are still threatening the tiger’s existence. All articles have their weak and strong points. This article is no exception as it too shares these two points, strong and weak.
The Humpback Whale (Megaptera novaeangliae) is one of the largest of the Cetaceans. They are fairly well known, even outside of the scientific community. They are identifiable by their dark grey dorsal color, white underbellies, very long pectoral flippers and by their habits of breaching and raising their tales above the water before diving. Their range expands tropical, temperate, and sub polar waters all around the world. They migrate in search of breading grounds and feeding grounds.
The whale shark (Rhincodon typus) is the largest fish in the world. The head is flattened and the wide mouth stretches almost as wide as the body. The dorsal fin is particularly large and the tail has a half-moon shape. The coloring of this whale is very distinctive. It has dark greyish-blue colour on the back and sides, and also pale yellow blotches.
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.
