What makes the tiger shark so threatening is that they continue to hunt even after a first attack. The tiger shark often hunts in shallow waters where humans swim, and they are prevalent in tropical waters and popular tourist locations, like Hawaii. Tiger Sharkįor many of the same reasons that great whites are dangerous, so are tiger sharks. Even when a stingray is dead, the sharp barbs can still injure a person. The pointed end can puncture the lungs and other organs. The sting isn’t the only thing that can be lethal, though. Stingrays have enough venom in the barbs (that look a bit like a thin tail) to kill an adult human. ![]() Steve Irwin, the famous Australian wildlife conservationist known as the Crocodile Hunter, died from a stingray barb to the chest. Stingrays don’t typically attack humans, but they have killed before when they feel threatened-whether they are in danger or not. Even if the shock itself does not kill a person, it can result in drowning. ![]() ![]() If an Atlantic torpedo ray feels threatened, it can produce enough of an electric shock to stun a human-up to 220 volts. While they camouflage themselves in the sand during the day, they can wrap their “wings” around their prey, or a human arm or leg, and attack at night. These rays don’t typically attack people without being provoked but hide under the sand during the day, which makes them a risk to step on. The Atlantic torpedo ray lives along the coast of North American, South Africa, and the United Kingdom. Every year, several people die from eating pufferfish, so this is a risk we certainly don’t advise taking. In Japan, meat from the blowfish is thought of as a delicacy but requires intense training to serve the correct part without killing those dining on it. If you encounter a pufferfish in the ocean, steer clear. Even worse, there is no current antidote. This toxin, called Tetrodotoxin, can kill up to 30 adults. The more dangerous part of a puffer, also known as the blowfish, is the toxin in its body. When pufferfish feel a threat nearby, they take in enough seawater to puff themselves up into a spiky ball. The pufferfish might look cute as it swims around unthreatened, but it can be seriously deadly. Moray eels have taken off fingers when attacking humans, so keep your distance if you spot one. Moray eels are in both tropical and subtropical waters, and if they feel vulnerable, they can attack humans with a powerful bite. Around 80 species of moray eels exist, and they are found in shallow waters with reefs and rocks where they can hide. The moray eel may not be venomous, but they have powerful jaws with sharp teeth. ![]() However, most human deaths from the textile cone snail occur from people picking them up on the shore or accidentally standing on them in the water. This snail lives in coastal waters off of Australia, Hawaii, French Polynesia, Eastern Africa, the Red Sea, and the Indo-Pacific region.Ī single textile cone snail contains enough venom to be lethal to 20 adults! Worse yet, there is no anti-venom for their sting, and it can kill a person within a few minutes.Ī snail might not initially sound like a threat because of its slow speed. While the textile cone snail is not technically a fish, it is worth making this list because it’s among the most venomous creatures in the ocean.

That’s why we rounded up ten of the most dangerous fish in the ocean and seas (in no particular order). With a growing human population, and more people snorkeling or SCUBA diving each year, injuries from dangerous sea life continue to rise. (You might be interested in reading about the Marine Animals with the Strongest Bites) While some of these oceanic dangers can cause minor stings or small bites, many are potentially lethal. Some of this sea life stays near the ocean floor but can still be a threat if stepped on or even touched. As of right now, we know of roughly 2,000 creatures in the oceans and seas that are poisonous or venomous to people.
