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.
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 Hammerhead shark is a fascinating creature, who are not like most other Sharks in the ocean. Ever wondered why their head is shaped weird? What is the purpose of it? How long do they migrate for? Description
Focus question: To cull or not to cull great white sharks Great white sharks are the biggest predatory fish in the ocean and they can grow to about 15 feet in size, although larger than 20 feet have been seen. Their name comes from the white underbellies of the sharks and their bodies are designed to blend in with the seabed. The great whites have powerful tails which makes them excellent swimmers that can travel up to 24 km/h. They have many rows of triangular shaped teeth and have a great sense of smell and even their body can sense electromagnetic fields produced by animals. They mainly eat sea lions, small toothed whales and sea turtles.
The Great White Shark The Great White Sharks, known mostly because of their white underbellies, are one of the most powerful aquatic animals in the world. They can swim at about 25 Miles Per Hour (40 Kilometers per hour) because of their strong muscles and forceful tails. In addition to that, male Great Whites can grow around 11.5 to 13.1 feet long, while females can grow from 14.8 to 16.4 feet long. This paper will demonstrate how Great White Sharks are an important part of their ecosystem, how their diets work and will adequately describe their habitats. As predators in their ecosystem, Great White sharks help maintain the coral reefs and seagrass habitats.
They are sometimes found in Brazil, the Caribbean, northwestern Africa, Philippines, and Hawaii. Great White Sharks travel in groups. The sharks are carnivores. They eat whales, sea lions, seals, sea turtles, and fish. When a mother has a baby shark it is called a pup.
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.
Sharks: The Evolution For roughly 420 million years, the greatest predator of the ocean has been swimming freely around in the water (450 Million Years of Sharks). Fish scurry away escape the rows of teeth in the jaws of a shark. With over 400 species of shark, how did they all get here? (A Timeline of Shark Evolution). Most importantly, how did they get such unique features that help them become the rulers of the ocean?
The largemouth bass have the ability to hide from their prey and provide protection against their predators through the process of abundant vegetation. Their surroundings is usually made up of clears waters so that they can use their vision to identify their prey. The range size in most environments is usually no greater than three meters. (Hannon, 1996; Iguchi and Matsuura, 2004) The largemouth bass is dioeciously, meaning they have separate sexes in reproduction, male and female.
Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.
Along the coastlines of the U.S.A, Africa and Australia, sharks, especially the Great Whites, have received a bad reputation as very aggressive predators that like to attack and eat human beings. There is a lengthy, tangles and gory relationship “between Carcharodon Carcharias and Homo sapiens”(ReefQuest). The Great White’s notoriety as a ruthless animal of prey is well-earned, yet these marine animals are not, as earlier considered, indiscriminate ‘’eating machines’’. “They are ambush hunters, taking prey by surprise from below or behind”(Encyclopedia of Life). Despite common beliefs about the threat to human beings, they do not attack people without a definite or convincing reason; therefore, the commonly held view of the “man-eater” is erroneous.
BACKGROUND AND RATIONALE A few decades ago the main pressure on populations of giant otter was poaching for the fur industry, but this has decreased favorably, however, now has emerged new anthropogenic pressures, including hunting, usually related to fishermen encounters with otters that could be affecting the effectiveness of their fishing nets; fishermen facing this scenario, tend in many cases to see these predators as competitors for fish resource, stating that these animals are the main causes for the actual reduction of fishing volumes (Guzman, 2005; Gomez & Jorgenson, 1999; Recharte et al, 2008;. Harris et al., 2005; Rosas-Ribeiro et al, 2012). That’s why among the major new threats to populations of P. brasiliensis are both incidental hunting and habitat degradation (Groenendijk, 2015).
How differrent about two kind of large tropical shark,the whale shark and the tiger shark? First of all, the whale shark is light blue and has dots on its body whereas the tiger shark is dark blue and has a stripe pattern on its body. The whale shark has legth 10 metres and weight 9 tonnes whereas the tiger shark has length 4 metres and weight 500 kilograms. So,the whale shark is bigger and heavier than the tiger shark.
They have pectoral fins, dorsal fins, and a vertical tail. The skin of sharks is very rough and made up of millions of sharp scales. Sharks have gills for breathing. What 's can be up to 3,000 pounds. They have a long and wide body, dorsal fins, and a horizontal tail.
