The deadliest fish in the world is the stonefish, which has some serious ability to cause harm! Stonefish are around 14 to 20 inches long and the same in width due to their extremely wide pectoral fins. They are found in tropical waters – including the Indian Ocean, Pacific, Red Sea, and the Great Barrier Reef.
Great White Shark
In the areas where they are most common, white sharks are responsible for numerous unprovoked, and sometimes fatal, attacks on swimmers, divers, surfers, kayakers, and even small boats.
Piranhas are a group of freshwater fish that are native to South America. They are known for their sharp teeth and aggressive behavior, which make them efficient predators in their freshwater habitat. They are typically found in rivers and streams, but can also be found in lakes and flooded forests.
While most species of tiger fish are not known to be dangerous to people, attacks on human beings are rare but not unheard of, especially by the goliath tiger fish.
Although there are stories about Goliath tigerfish killing and eating humans in the Congo, none have been substantiated. However, these fish have been known to attack humans, causing substantial wounds due to their bite force.
Biggest recorded size? While reports vary, the largest tigerfish ever caught was the goliath tigerfish (Hydrocynus goliath) said to have weighed an incredible 70kg.
This tells the cleaner wrasse that they want a cleaning. The tiny cleaner wrasse will go right into the larger fish's mouth or gills and remove parasites and mucus right off of the sharp teeth, much like our human dentist uses a dental pick to clean plaque off of human teeth.
A fish with human-like teeth has been caught in the United States. A photo of the fish was shared on Facebook this week by Jennette's Pier, a fishing destination in Nag's Head, North Carolina. It was identified as a sheepshead fish, which has several rows of molars for crushing prey.
An avid fisherman in Oklahoma recently caught something unusual in his neighborhood pond. Using a piece of bread as bait, 11-year-old Charlie Clinton reeled in a South American fish with humanlike teeth. It's a relative of the better-known piranha, but the pacu is a vegetarian.
1. The Puffer Fish. The puffer, also called a swellfish or blowfish, inflates when disturbed or threatened. The puffer fish has a highly toxic substance called tetrodotoxin, which is located in its liver, ovaries, intestines and skin.
The hardest fighting fishing pound-for-pound are billfish, tuna, grouper, mahi mahi, and tarpon in saltwater, striped bass, steelhead, and salmon in intercoastal waters, and carp and northern pike in freshwater. Saltwater fish are generally much harder on gear and stronger fighters than freshwater fish. What is this?
1.Box jellyfish
Considered the most deadly creature in the sea, the box jellyfish may be beautiful to look at, but it has enough venom to kill a human in a matter of minutes. Native to Australia and found in Indo-Pacific waters, the box jellyfish has around 15 tentacles that can reach lengths of upto three meters.
Most sources believe that the fastest species of fish is the Indo-Pacific Sailfish, Istiophorus platypterus. According to Johnson and Gill (see below) the species has been clocked in excess of 110 km/h (68 mph) over short periods. The Indo-Pacific Sailfish grows to over 3.4 m in total length and 100 kg in weight.
Recovery usually takes about 24 to 48 hours. Outcome often depends on how much venom entered the body, the location of the sting, and how soon the person received treatment. Numbness or tingling may last for several weeks after the sting. Skin breakdown is sometimes severe enough to require surgery.
This aptly named fish (Anoplogaster cornuta ) has long, menacing fangs, but the adult fish is small, reaching only about 6 inches (17 cm) in length. It's teeth are the largest in the ocean in proportion to body size, and are so long that the fangtooth has an adaptation so that it can close its mouth!
Great white shark
The terrifying star of 'Jaws' is the largest predatory fish on earth, and great white sharks have around 3,000 teeth at any one time, arranged in rows along their upper and lower jaws.
With its razor-sharp teeth — resembling that of a piranha –the barracuda is one of the fiercest fish in the oceans. They are found in nearly all tropical and subtropical bodies of saltwater throughout the world.
The shark and remora relationship benefits both species. Remoras eat scraps of prey dropped by the shark. They also feed off of parasites on the shark's skin and in its mouth. This makes the shark happy because the parasites would otherwise irritate the shark.
Why does every dental office seem to have an aquarium or water feature? You may have noticed that an aquarium or some other type of water feature in the reception area seems to be a near universal staple in a dentist's office. The reason for this is because it's a form of stress relief for patients.
The Nile crocodile is the only known predator of mature goliath tigerfish.
The record for the largest tiger shark is 24.6 feet long and 1,780 pounds. These sharks are saltwater fish that inhabit tropical waters worldwide.
Sturgeon are the largest of the freshwater fish. The beluga sturgeon in Russia is the largest freshwater fish in the world. The white sturgeon is the largest freshwater fish in North America. White sturgeon have been reported to reach lengths of 15-20 feet and weights of nearly one ton.
