Where does it live?

The Blue Shark or Prionace glauca is most often found in swimming in the open ocean and is never really found near the coastal shorelines. According to FLMNH (2012), this species of shark can be found hunting and living in temperate or tropical waters all over the world. These sharks usually blend into their environment like living in “kelp forest” or “coral reef areas.”(PBS, 2012) Blue Shark prefer cooler water temperatures, but they have been known swim in warmer waters.

What does it look like?

The Blue Shark has a bright blue color or indigo color, but their underbelly is usually a grayish white color. This species of shark has small white rings around its eyes and a pointed nose that will help humans identify them. According to Enchanted Learning (2012), this species of shark has a body that is sleek yet tapered, which allows it to be a graceful swimmer. The adult Blue Shark is about 12 ft. long and it has a moderate sized dorsal fin that sits further on its back. This allows this species can jump out of the water and is known as one of the fastest swimmers due to its elongated caudal fin.

What does it eat?

The Blue Sharks color helps camouflage the shark whenever it is swimming or hunting for its preferred prey. This species of shark has serrated and pointy teeth that help the sharks grab slippery prey like fish. According to Enchanted Learning (2012), the Blue Shark prefers squid but will eat almost anything that it decides to hunt. These sharks also hunts for prey like sardines or anchovies, but this shark is known as an opportunistic feeder.

Do they reproduce?

Blue sharks gives birth to live pups, but they can have anywhere from 4-135 pups with each litter they have. However, a normal litter of pups would be about 25 to 50, but more has been reported over the years. According to Canadian Shark Research Laboratory (2012), newborn pups are born after about 9-12 month of gestation and the pups are about 16- 20 inches at birth. The female may wait months or years before she begins to ovulate and decides to reproduce again.

Are they dangerous?

Blue Sharks are dangerous to swimmers, because there have been recorded attacks on people by this species of shark. However, fishermen are catching these sharks, because they can become a nuisance.The shark now has fewer numbers than it has in the past, due to fisherman catching and killing these majestic creatures. Unfortunately, according to CSRL (2012), this shark is blamed for attacking victims of air and sea disasters.

The basking shark is considered the second largest fish or shark, when compared to the whale shark. According to Sharks-World, this gigantic creature is also known as Cetorhinus Maximus, by scientists and researchers who collect vital information from these animals. Thankfully, they do not prefer to eat humans instead they filter feed, just as the whale shark does. They are slow moving and an unusually large mouth. In which they filter feed.
They are not dangerous to humans, because the giant shark is usually enjoying using its wide mouth to eat plankton. They have gills which filter out the items that they don’t want, while allowing them to eat all the plankton that they want. According to Sharks-World, these giant sharks can measure up to 33 feet long and the shark can weigh up to 4 tons. The most common names are the big-mouth shark, sun-fish, bone shark, and elephant shark.
The basking shark enjoys swimming and living in the coastal waters, which are warmer and offer plenty of plankton to snack on. Additionally, these giant sharks may travel alone or in groups of over 100 members, as well as travel with their mate. According to Sharks-World, they tend to stay near the surface, so they can filter feed using their mouth to process 1500 gallons of water each hour. These amazing animals are in need of protection before they become extinct and future generation will never get to see one up close.
The commercial fishing industry allows shark hunting for meat and shark liver oils, as well as other valuable parts of the shark that can be sold on the open market. According to Sharks-World, sometimes these giant sharks are mistaken for a great white shark, but the basking shark has smaller eyes and large gills. This shark’s mouth is about 3 foot wide, which allows them filter feed using the gill rakes found in the sharks gills that encircle its head.
The sharks don’t hibernate but they do migrate to deep waters or other coastal areas, during certain seasons. According to Sharks-World, these sharks vary in colors like blue, white, dark brown, and black which may identifying one a little difficult unless you know what they look like. However, In order to keep the giant sharks from being hunted, we as a generation must try to offer some type of protection now. If not, we will lose all chances of our future generations ever seeing a basking shark, except in school books or the encyclopedia.

Whale sharks are a majestic beast, which fascinates scientist and tourist alike, yet many misunderstand this gentle giant. Learning more about this species of shark will help people begin to understand that the whale sharks are not dangerous. According to Shark-World, the whale shark is also known as the Rhincodon typus, which has been confirmed as a largest fish in the entire world. Scientists and tourist have chosen to go scuba diving with these majestic creatures, yet they found them to be docile and nonthreatening to humans.

According to Sharks-World, the whale shark is the largest species of shark in the world, which has been on this planet for millions of years according to scientists. The largest recorded whale shark was 40 feet in length, but some say they have seen whale sharks that are about 60 feet long. They are also known as the largest species of this on earth and can weigh over 20 tons. However, despite their massive size, they are generally known as gentle giants.

A whale sharks mouth is 4 feet wide and they are filter feeders, but their preferred meal is plankton or small fish. According to Sharks-World, the gentle giant prefers to live in warm waters like the ones found in Mexico, tropical seas, and Australia. During the spring, the whale shark migrates to the continental shelf, which is found on the West Coast of the Australian sea. This area of the Australian sea allows the whale shark to find plenty of plankton to eat and thrive on.

The gentle giant has a flattened head and a blunted snout just above its massive mouth, which has short barbels that protrude from its nostrils. According to Sharks-World, the whale sharks body is bigger that a school bus, which makes this gentle giant the biggest fish on the planet. The sharks back and sides are a dark gray to a brownish color with white spots. The gentle giants belly is white and it has two dorsal fins, which are set facing the rear of its body.

The gentle giants have a massive tail, which helps them swim when migrating or just hunting the food they crave like plankton. According to Sharks-World, these gentle giants are considered to be a threatened or vulnerable species, but they are still hunted in Asia and the Philippines. These giant sharks are docile and will allow a swimmer to interact with them, as well as hitching a ride. It is up to us and future generations to help save this majestic creature from becoming extinct.

According to Sharks-World, these sharks are blue in color and can be around a half a ton or 1000 lbs while they can grow to be 12 feet long. The mako sharks usually don’t swim near humans, but humans have been attacked by this aggressive shark. Fisherman have always told tales about this shark swimming faster than their boats and jumping high enough to jump over their boats, as well.

Pound for pound most powerful shark in the ocean and they are narrowed bodied, but have flat surface at the end of their body that is right by their tail. Their tails are up down from tip to tip, but their bodies are streamed lined for speed and agility when hunting prey. According to Sharks-World, some mako sharks may prefer to swim near the shore in warm water, whiles others prefer colder or deep water. These sharks can be found in oceans around the world, but many are found in the waters surrounding Tahiti.

This shark has the speed and agility to track large animals in the sea like: dolphins, fish, and tuna. This shark is the fastest shark in the sea and generally swimming at speeds of 35 miles per hour, but when hunting or migrating they can swim up to 60 miles per hour. The female and male mate, but the eggs remain in the female until they hatch and she will have up to 18 pups which are over 2 ft. long. (Source: Sharks-World, 2015)

Beautiful Creatures

Beautiful Creatures

Did you know that the Killer Whale or Orca is the largest species of dolphin? They have 4 inch teeth unlike any other dolphin species, which you may have seen while reading a book or in a magazine. There a three groups of pods or herds that the orcas may live in and they eat differently as well. One is called transient and another being called resident, as well as the off shore group.

What does it look like? The Killer Whale is identified by its black and white markings along with flippers on each side of the Orca, as well as a prominent dorsal fin. These majestic yet dangerous creatures are nicknamed, the cows of the sea. According to National Geographic (2012), these mammals can reach 22-32 feet long and weigh up to six tons. These mammals can live up to 40 to 60 years, but only when they are not killed due to whales and dolphin hunting.

What does it eat? These majestic mammals are predators, who hunt for marine mammals like seals or sea lions. According to National Geographic (2102), two Orcas will hit the iceberg causing it to rock back and forth. Unfortunately, this rocking motion causes it prey like a seal or sea lion to lose its footing. Then, the prey slides into the Orca’s mouth or into the water, where both whales will play with it and they slap it between each other enormous tails. The resident killer whale will main eat fish like salmon, but the transient whales will eat other animals like sharks or sea lions.
