Deep sea creatures are some of the most fascinating creatures on Earth, but they also happen to be some of the biggest and most intimidating creatures you can find anywhere in the ocean. All these weird deep-sea creatures have adapted to survive in an environment with no sunlight and very little food, which often makes them huge and ferocious looking. When you’re this far from land, predators come from all directions, so it pays to have whatever size advantage you can get your hands on. Here are ten massive deep-sea creatures that will make you think twice about taking an impromptu scuba dive in the middle of the ocean!
1) Giant Trevally
The Giant Trevally is the 2nd biggest saltwater fish in the world. It’s not as tall as some of the other giants on this list, but it has a long, stout body and huge mouth. Giant Trevally live deep in reefs or other rocky areas at depths from 240 to 600 feet below sea level. They are known for being fast swimmers and very aggressive predators which they use to hunt unsuspecting prey.
2) Giant Squid
This deep-sea creature is considered one of the largest of all squid. The giant squid can reach a maximum length of 43 feet and weigh 454 pounds. They live in mostly in the North Atlantic Ocean between North America and Norway but some have been found as far south as Chile. The giant squid’s head has arms that are about 40 feet long with large suckers for gripping prey tightly, tear it into pieces and then consume it whole.
3) Colossal Squid
Found off the coast of Chile and New Zealand, the colossal squid has never been seen alive in its natural habitat. It’s really just a guess, but the Colossal Squid is one of the largest invertebrates ever discovered with a size range between 33ft to 100ft long. However, it’s hard to say for sure because scientists have never seen this magnificent animal in its natural environment. One thing is for sure though; it won’t be coming after you anytime soon!
4) Southern Elephant Seal
Southern Elephant Seals are one of the largest living seals on Earth, they grow to lengths of 6.6 feet (2 meters) and weights of 3,500 pounds (1,600 kilograms). Seals have amazing olfactory and tactile senses and use them in locating prey hidden beneath the sea floor and in catching prey at night. They are capable of diving more than 500 feet deep for 30 minutes without oxygen tanks.
5) Sperm Whale
Sperm whales can grow up to 59 ft long and can weigh as much as 57 tons. They are the largest toothed whales in the world. The males have a big head that is thought to be used for knocking an opponent off their feet during competition for females, or just when playing with other males.
6) Humpback Whale
The humpback whale can grow up to 50 feet long, the length of a school bus. They live in the tropics and feed on krill (tiny shrimp like animals) and small fish. To eat they suck in water then force it out through their baleen which catches their prey in its gaps. Then they swallow their catch and the water together! That may sound disgusting but whales are actually really clean. All that comes out when they vomit is half digested krill!
7) Great White Shark
The Great White Shark is a type of cartilaginous fish, and the only member of the genus Carcharodon. It is found in the coastal surface waters of all the major oceans and is most commonly thought to feed on large mammals such as seals, sea lions, and dolphins, but will also attack other species.
8) Moray Eel
Moray eels are found in both salt and fresh water. Some species can be found as deep as 600 ft below the surface of the ocean. Their bodies have a variety of patterns and colors, ranging from brown to yellow to green. Morays feed on crustaceans, urchins, small fish, and other sea creatures using their fangs which are located inside their jaw that project forward when they open their mouth for food intake.
9) Goliath Tigerfish
The Goliath Tigerfish, with an imposing appearance and a frightening set of teeth, can measure up to six feet in length. The Goliath Tigerfish is the world’s largest freshwater fish. In Latin, goliath means giant; this tigerfish lives up to its name. It resides near the bottom of lakes and rivers in African countries like Cameroon and Congo, though it has been spotted as far away as Indonesia.
10) Hammerhead Shark
Growing up to 12 feet long, the massive hammerhead shark is the world’s second largest species of shark. They can weigh up to 2400 pounds, but they’re more likely to weigh 500 pounds or less. Its brain case is proportionately large, so that it can sense electrical fields generated by prey hidden in the sand and behind rocks.
