Sea Beasts are one of the most ferocious types of animals that inhabit the seas of theOne Pieceworld. They are ginormous aquatic mammals, and they greatly resemble some of the creatures living on land. Sea Beasts are smaller than Sea Kings, but the one thing that they have in common is their ability to strike fear into the hearts of even the most intrepid characters. Sea Beasts also have many natural predators, but that doesn’t deter them from living freely in the seas. There are many Sea Beasts in the series, but some are far more dangerous than the rest.
7Sea Dog
Sea Dogs, as the name suggests, are Sea Beasts that resemble dogs. There have been two separate sightings of Sea Dogs in the series. It was firstintroduced in Jimbei’s cover story, in which it had a mustache, a police badge, and a hat.
The second Sea Dog resembled a bulldog, and it was a member of the New Fish-Man Pirates. Both the animals seemed rather calm and weren’t nearly as aggressive as some of the other Sea Beasts.
6Sea Cat
Sea Cats are considered less dangerous than other living organisms found in the sea. For this reason, they have been classified as a type “A” creature that is friendly toward humans. A young Sea Cat is usually around 3 meters (9'9") tall, but a fully grown adult can match the stature of other Sea Beasts.

Sea Cats are considered sacred by the people of Alabasta, which is why they overlook their transgressions. The people of the land go out of their way to verify that these creatures are not harmed at any cost. Despite being classified as friendly Sea Beasts, these creatures are knownfor attacking passing ships.
5Sea Cow
Sea Cows are akin to normal cows in many ways. They have curved horns and patchy coloring. The noses of the two creatures are also similar. They do share a few differences, the biggest being that Sea Cows are carnivorous. These Sea Beasts also possess a tail and fins that allow them to travel at a speed of 70 km/h, making it almost impossible to escape.
Momoo is the only known Sea Cow in the series, and it was apart of the Arlong Pirates. Sea Cows are also able to move on land, as evidenced by Momoo’s destruction of a village. Sea Cows also have hardened skin that protects them from attacks from other creatures.
4Sea Rabbit
Sea Rabbits share traits with regular rabbits, but they are far from the adorable fluffy animals that a person might want to pet. Sea Rabbits are ferocious creatures that pose a threat to other animals and humans.

So far, only one Sea Rabbit has been seen in the series, and the Straw Hats encountered it near the Red Line. Due to its feral nature, the Sea Rabbit wasted no time in attacking them. However, it was taken down by awell-placed punch by Luffy. After being defeated, the creature spat out Camie and Pappag, whom it had devoured earlier.
3Sea Lion
Sea Lions are absolutely massive; they can grow as big as 55m (180'5"). Given their size, it is not surprising to see people avoiding them at all costs. A single Sea Lion could easily destroy a fleet of ships by itself.
The New Fish-Men Pirates' army had a Sea Lion in its ranks. Once the crew was defeated, the Sea Lion went on a rampage and destroyed many structures within its surroundings.
2Sea Bear
Sea Bears have white fur and the same face as regular bears. These fearsome animals can grow as tall as 50m (164ft). The New Fish-Man Pirates had taken control of a Sea Bear and used its might to cause problems for the Straw Hats and the other people living on Fish-Man Island.
After the New Fish-Man Pirates were taken down by the heroes, the Sea Bear became uncontrollable and started attacking all the people within its reach. It only stopped after several fish-men frightened it with fire.
1Sea Beast Weapons
The Sea Beast Weapons are superior to the regular Sea Beasts as they have been enhanced by Dr. Vegapunk. The scientist captured many Sea Beasts and fitted them with various cybernetics, which gave them more power. Vegapunk’s goal was to use the Sea Beast Weapons to scare away any possible intruders.
The Sea Beast Weapons were introduced inthe Egghead Island arc, and they temporarily stopped CP0 from reaching Vegapunk’s laboratory. Even though CP0 managed to destroy two of the Sea Beast Weapons, they were not fully confident of beating all of them. So, the assassins abandoned their ship, after which it was immediately destroyed by the Sea Beast Weapons.
