The 70cm deep sea swallowed the fish in the aquarium

The wrinkled sea worm usually stays in the tank but when it finds the falling fish, it will come to eat and it only takes a few minutes to swallow.

Nagoya Port Public Aquarium in Japan shares the moment a sea ​​worm called ice worms or Nemertea spread their mouths as large as possible to swallow fish flesh. This is one of four marine pests cultured in the aquarium since 1991. Due to its frightening appearance, they were not displayed until 2015.

The worm mouth is as big as it can to swallow fish.

Chizuru Sato, a spokesperson for the aquarium, said the sea worms attracted attention after a contest to search for strange creatures . "Most people don't know them, but thanks to the competition, many people watch them with interest, " Sato said.

Researchers know very little about this Nemertea marine worm . "We do not know how long they live. They have been raised in the aquarium for more than 28 years. We mainly feed the deep-sea worms. In nature, they live in the water bottom of the South Ocean, At a depth of 16 - 395 meters, specimens were collected in the area around King George Island , " Sato said.

The staff at the aquarium said that their deep-sea colonies were over 40 years old. At nearly 70cm in size, they are among the longest creatures in the aquarium. They lay still in the tank most of the time but always rushed to eat the fish body that fell to the bottom of the tank.
