Thresher shark


The thresher shark is one of the most dangerous sharks. This large fish can grow up to 10 feet long and weigh over 500 pounds. They are found in warm waters around the world. Their diet consists mostly of squid. These sharks are known to attack humans, although it is rare. In fact, there have been no recorded attacks since 1950. There is still much about this shark that we do not know. For example, scientists don’t even know how many thresher sharks exist worldwide.

Scientists classify the thresher shark under the genus Alopias because they believe it belongs to the same family as the albacore tuna. Some people call threshers “sharktooth”, but that name doesn’t seem to fit. Scientists say that the name “thresher shark” is derived from the sound the animal makes when it bites something underwater.

Common thresher

The common thresher is a fish belonging to the family Atherinidae. This species lives in shallow waters along the coast of Africa and Asia. In the wild, it feeds mainly on small invertebrates like mollusks and crustaceans. Its body is elongated and slender, and it grows up to 20 centimeters long.

The scientific name “Alopias superciliosus” refers to the fact that the fish has a large number of scales around its eyes. These are called supercilia, and they help the animal see better under water.

The binomial name is derived from the Greek word alopes meaning “threshing,” referring to the way in which the fish uses its mouth to move sand and silt out of its burrow.


The common thresher shark is a fairly robust shark, growing up to 4 m long. Its body is cylindrical and elongated, tapering toward the tail. This shark has a relatively short, blunt nose and a rounded, slightly protruding forehead. A thick, muscular ridge runs along the center of its back. The dorsal surface of the head is marked by three longitudinal ridges running from the tip of the snout to the base of the caudal fin. These ridges run parallel to each other and converge near the rear edge of the caudal peduncle. There are six pairs of gills, with the fifth pair being larger than the others. The skin is covered with tiny pits, giving it a rough texture. The fins are narrow and extend well beyond the length of the body. The anal fin is positioned far behind the pelvic fins. The pectoral fins have a slight notch in front of the tips. The caudal fin is broad and rounded, with a concave leading margin. The coloration is variable, ranging from light grayish brown to dark brown above, with lighter sides. Juveniles are generally paler than adults. Some specimens show white spots on the belly


The United States Census Bureau does not track the number of people living in the country. However, it does keep track of how many people are alive. This data is called vital statistics. In addition, some states do count births and deaths within their borders. These figures help determine whether the population is growing or shrinking.

In 2017, the total population was estimated to be 328 million people. The population grew by about 0.5% over the previous year. During the same period, there were about 7.4 million births and about 5.8 million deaths. The birth rate was about 14.9 per thousand people while the death rate was about 12.1 per thousand people.

Fishing Rate

The number one question I hear about fishing is how many fish are caught per hour. This is called the “fishing rate.” There are different ways to calculate it.

We use the average length of the fish you catch as well as the total weight of the fish you catch. We divide the total weight by the average length to determine the “fishing rate”.

For example, let’s say you catch 3 pounds of trout every day over a period of 30 days. You weigh each fish and find that the average length is 2 inches. Your daily catch is divided by the average length to come up with the “fishing rate”:

This calculation assumes that you’re catching the same size fish every day. If you’re catching larger fish, you’ll want to adjust for that.

Life History

Thresher Sharks – Orycteropis Spengleri

The thresher shark is one of the most common species of shark found off the coast of South Africa. They are typically found around depths of 200m, although they have been known to dive down to 600m. They feed mainly on fish, squid, octopus, crustaceans and cephalopods.

Male threshers grow up to 3.5 meters long and weigh about 90kg. Females are slightly smaller, growing up to 2.8 meters and weighing 80kg.

Their lifespan is unknown, but it is likely to be around 20 years.

This species is ovoviviparously viviparous, meaning that the embryos develop inside the mother’s body and are nourished by a yolky placenta.

A young thresher shark measures approximately 1.4 meters in total length at birth.

They swim slowly while feeding, cruising along at speeds of 0.2-0.3 knots.

Where can you Find Thresher Sharks in Malapascua?

Malapascua is a tiny island located just off the coast of the Philippine city of Cebu. It’s home to some beautiful beaches, great diving sites, and even a few unique attractions like the Thresher Shark Cleaning Station. But what makes Malapascua such a popular destination among divers is the fact that it’s home to one of the world’s best examples of Pelagic Threshers – big, massive, and incredibly rare.

The island is also home to several other interesting marine life forms, including sea turtles, manta rays, whale sharks, and even giant clams! These animals regularly congregate around the island’s coastline, making it easy for divers to see them up close. In fact, there are dozens of different species of fish and coral found near the island, meaning that no matter where you go, you’re sure to find something amazing!

Thresher Shark Conservation Status

The International Union for Conservation of Nature (IUCN) lists the conservation status of the thresher shark as “least concern.” This rating is based on the fact that it is widespread throughout tropical waters and does not face significant threats. However, there are still many things we do not know about this species. For example, scientists don’t know how many thresher sharks live in the wild and what population trends are like. They also don’t know much about the reproductive habits of this species.

Thresher Shark Facts

Threshers are among the most well known shark species due to their large size and impressive jumping ability. These sharks live near coastal areas where they hunt for small schooling fishes such as herring, mackerel and squid. Their name stems from the fact that threshing refers to the way they use their tails to move prey towards their mouths.

These sharks can grow up to 10 feet long and weigh over 2,500 pounds. They are considered harmless to humans because of their slow speed and lack of aggression. However, it is important to note that they do attack larger animals such as seals and even humans. There are no confirmed reports of people being bitten by threshers, however, some attacks have been recorded.
