Top 10 Most Dangerous Animals in the Ocean
The ocean is a mysterious place. It is suggested that scientists do not even know half of what takes place below the surface of most oceans. There are points of the sea that are so deep that they have yet to be reached by humans.
In addition to being a mysterious place, the ocean is also a dangerous place. There is no shortage of dangerous creatures that are known for being blood thirsty and territorial. From sharks to crocodiles, there are more than a few different dangerous animals lurking in the depths of the world’s bodies of water.
Some of the most dangerous animals in the ocean are not a surprise. After being immortalized by the media and Hollywood as blood thirsty predators, some of these sea animals are the most feared on Earth. However, some of the most dangerous animals get little to no air time.
From ancient animals that live on both land and water to those who rarely come up from the depths, there are many things that make these animals both unique and dangerous.
If you’re not sure what to look for in warm coastal waters or in the depths of a coral reef, read on to learn about the top 10 most dangerous animals in the ocean.
10. Great White Shark
The great white shark is possibly the most famous predator of the seas. As the inspiration of more than a few Hollywood horror films, it has become known as a dangerous and bloody-thirsty creature that is willing to attack almost anything that it deems to be food.
This kind of shark is a carnivorous fish. It often grows to be 15 feet long; however, some can grow to be more than 20 feet in length. Around the size of a school bus, this shark can weigh in at an average of 5,000 pounds.
There are several characteristics that make this shark the most dangerous animal in the ocean. The first is its size and incredible power. Even though it is so large, it can see up to 15 miles per hour. Their powerful tails help propel them through even the choppiest seas.
The great white is also known for its sharp teeth. Any given shark will feature around 300 triangular teeth that are serrated for extra cutting power. The teeth line several rows of a shark’s powerful jaw. In addition to the force of its bite, these teeth make it easy for a great white to strip flesh off of its prey
Sharks hunt their prey with their sense of smell. These dangerous predators can smell a single drop of blood in 25 gallons of water, and they don’t have to be close to it, either; they can smell it up to three miles away. This helps them find prey that is already wounded, which is easier to catch and kill than healthy prey.
Most of these sharks are found in cooler waters along coasts. Their proximity to humans make them one of the most feared fish on Earth. There are often around 100 shark attacks around the world each year, and around a third of these attacks are committed by great whites.
Although these attacks are dangerous, many of them are not intended to kill. Scientists believe that these sharks are just trying a new kind of prey out of curiosity. Because the sharks often bite and then swim away, scientists do not believe that sharks intend to specifically hunt humans.
9. Sea Snake
Sea snake is the name given to many different species of snakes that live in the sea. There are around 60 different types of sea snakes, and 14 of these species live on or near the Great Barrier Reef off the coast of Australia. There are two distinct groups of sea snakes today: the Laticaudids and the Hydophiids. They are believed to have evolved from the snakes that lived on the continent nearly 30 million years ago.
The sea snake’s shape aids its ability to swim. Their tails have evolved to include a paddle on the tale to help propel them through the water. They can grow to be between four and five feet long on average. There have been documented cases of a sea snake reaching almost 10 feet in length.
Although they live in the sea, they still require oxygen and do not have gills. However, their lungs allow them to stay underwater from anywhere from half an hour to two hours at a time. Their lungs work very efficiently to facilitate this. They also take oxygen from the sea water and absorb it through their skin.
Sea snakes are dangerous because every species is incredibly venomous. Although most sea snakes are reported to avoid humans, a single bite can be very dangerous. The snakes are most active when they are mating, as some reason, the snakes will become more curious about humans during this season.
8. Blue Ringed Octopus
Not many people consider the octopus to be very dangerous, and they are often sea creatures that are transformed into cartoon characters on children’s television shows. In other instances, in many places across the globe, an octopus is considered to be a part of a delicious meal.
However, not all octopuses are friendly sea creatures. The blue ringed octopus is one of the deadliest creatures in the sea. They are mostly found around Australia as well as around the borders of the Indian and Pacific Oceans. Although only a few people encounter this dangerous cephalopod each year, several of the injuries prove to be fatal.
The reason that the bite of this octopus is so dangerous is precisely because it looks so innocent. This octopus can be found in waters that are near to the coast, and it is not afraid of beaches. When someone is bitten by one of these octopuses, they have often picked it up or tried to get a closer look at it.
The bite is often small and not very painful. The octopus rarely creates a large bite and it does not often bleed very much at all. It also does not swell or change color. As a result, few people worry about this kind of bite and they do not go to the hospital. In the case that they do go to the hospital, it often takes a long time for a doctor to determine that they have been bitten by an octopus.
These bites result in the octopus putting venom into the victim’s body. However, the jury is out on whether or not the octopus even needs to bite a person to poison them with venom. Some believe that the venom can actually move directly through a human’s skin.
After someone has been infected by octopus venom, the side effects begin very quickly. After 10 minutes, those who have been infected find it hard to breath or swallow. They also feel weak and number and experience the onset of parasthesias.
If the venom takes over, victims will often see the failure of their respiratory system and will then die of cerebral anoxia.
The lionfish is another well-known venomous fish. However, people would not believe it was venomous when they are looking at it. Although its color tells other animals to back away, its zebra stripes and long fins play well for divers with underwater cameras.
The lionfish has dorsal fins that are the shape of needles. This is how they deliver venom to both predator and prey. It is a carnivorous fish, and it prefers to eat shrimp and other fish. To catch its prey, it will use its fins to guide smaller fish into a trap and then swallow them.
The lionfish mostly lives in the reefs in the Indo-Pacific oceans. However, they can be found anywhere there is warm water. This fish is not very big and it only grows to be around a foot long. It weighs somewhere around two and a half pounds.
Most lionfish are caught to be kept in aquariums but some people eat them as food. When left alone in the wild, the average lionfish lives up to 15 years.
A sting from a lionfish is rarely fatal; however being stung is very painful. It often results in difficulty breathing as well as nausea.
6. Saltwater Crocodile
The saltwater crocodile is often referred to as the most dangerous animal in Australia, as it thrives both on land and in the water. When a person is near their habitat, there is no safe space to hide from these dangerous and aggressive reptiles.
Saltwater crocodiles are huge and powerful creatures. They can grow up to 17 feet long and weigh around 1,000 pounds. However, huge crocs that grow up to 23 feet long and weigh 2,200 pounds can be found.
These reptiles are excellent swimmers and can be found not only on land but far out at sea. They hunt in both environments, and they will eat anything that they can find. They can kill animals as large as a water buffalo on land and they can even kill large sharks in the water. They will use their powerful bodies to grab their prey, and then drag it under the water until it drowns.
Saltwater crocodiles usually kill only one or two people every year. However, they have the potential of doing more damage as more people wander into their habitats. These animals are very territorial and will indiscriminately kill or maim anything that gets in their way.
Crocodiles are not endangered or extinct. They are very powerful and hardy and at home in many different environments.
