13 Animals That Are About 50 Feet (ft.) Long

If you decide to travel looking for land animals around 50 feet long, you will be wasting your precious time. It might be easier to come across a unicorn than a land animal closer to 50 feet long.

However, when you take a deep dive in the sea, you might come across one or two. Science is fascinating, and through scientific research, we have managed to find a few aquatic animals that are 50 feet long.

This list summarizes 13 of the giant animals you can find reaching 50 feet.

1. Whale shark

The whale shark is a filter-feeding, slow-moving carpet shark and a gigantic known living fish species. These animals can grow over 50 feet, with the largest ever recorded being 61.7 feet.

However, there have been various unverified records of longer whale sharks. In addition, the shark is also known for being the most prominent non-mammal vertebrate.

2. Lion’s mane jellyfish

The lion’s mane jellyfish is also called the giant jellyfish, hair jelly, or arctic red jellyfish. It is considered the largest jellyfish species and can be found only in the cold, boreal waters in the northern Atlantic, Arctic, and northern Pacific Oceans.

These jellyfishes can be around 50 feet long, with the largest on the record being 120 feet long. They mainly feed on fish, small crustaceans, planktons, and jellyfish.

They can weigh around 200 pounds and are mainly preyed on by sea turtles.

3. Sperm whale

The cachalot, also known as the sperm whale, is among the gigantic toothed whales and the largest tooth predators.

It is the only extant member of the Physeter genus and one of the three living species of the sperm whale family.

These animals are around 50 feet long and can grow over 60 feet. Before whaling, it is believed the population of sperm whales topped 1.1 million, but today the American Cetacean society thinks they have gone down to around 300,000.

4. Giant oarfish

The giant oarfish is one of the fish in the Regalecidae family that are distributed almost everywhere worldwide except the Polar Regions.

These fish are also called the kings of herrings, pacific oarfish, or ribbonfish. They are known for their slender and elongated bodies, spanning over 50 feet long.

The longest oarfish recorded was 110 feet long, which explains why these fish are the longest bony fish globally.

5. Basking shark

The basking shark ranks as the second-biggest existing shark and fish after the whale shark. It is also among the three shark species that feed on planktons alongside the megamouth and whale sharks.

It spans around 50 feet long and is distinct from other shark species, given the greyish-brown color. Adult basking sharks can weigh over 5 tons and move at a speed of 2 miles per hour.

6. Blue whale

The blue whale is a baleen whale and is considered one of the giant marine mammals. These animals can reach 50 feet, with reports of the most enormous blue whale being 98 feet long.

This gigantic mammal can weigh around 199 metric tons, making it the most giant animal ever to exist.

The blue whale can be identified with its light underbelly and greyish-blue dorsal fins. They can live to be over 90 years old in the world.

7. Bootlace worm

The bootlace worm is one of the world’s longest animals and one of the most popular ribbon worm species.

These animals can reach around 50 feet long, although there have been reports of a 180-foot bootlace worm washing up on the shore of St. Andrews, Scotland, in 1864.

These worms mainly habit cooler waters in Great Britain, Norway, and the west coast of Sweden.

8. Bowhead whale

The bowhead whale is one of the baleen whales of the family Balaenidae and the only member of the genus Balaena.

 It is the only baleen whale native to the subarctic and Arctic and is named after its massive skull. The bowhead whale can reach over 50 feet long, with the baleen plates being around 13 feet long.

Making these animals have the largest mouths among all animals.

9. North Atlantic white whale

Baleen whales are some of the largest animals, and the North Atlantic right whale is one of them. These whales are among the three right whale species in the genus Eubalaena.

The North Atlantic white whale is around 50 feet long and can weigh about 70 tons.

The largest of them was 61 feet long, weighing 106 metric tons.

10. Sei whale

The Sei whale is considered the third-largest rorqual species following closely behind the blue whale and the fin whale. It lives in almost all oceans in the world and neighboring seas.

These robust animals are approximately 50 feet long and prefer to live in the deep offshore water. They, however, like to stay away from tropical and polar waters.

There are around 80,000 sei whales worldwide, which is a third of the entire population before the whaling craze in the 1800s and 1900s.

11. Southern right whale

The Southern right whale is a close relative of the Northern right whale that belongs to the genus Eubalaena.

They primarily inhabit warmer waters south of the Equator, which provides conducive growth environments.

They can reach lengths of up to 50 feet and weigh over 23 tons. In 2009, there were 13,600 Southern right whales, and the number might have gone up due to controlled whaling.

12. Fin whale

The finback whale, fin whale for short, is a common rorqual that was previously known as the herring whale. It ranks second among the cetacean species after the blue whale.

These whales are around 50 feet long and can amass weights of up to 48 tons.

Their primary diet mainly included small fish like herring, sand lance, capelin, and squid.
