Many people think the shark to be an insatiable beast, attacking humans without a moment's notice.
But sharks in fact eat surprisingly very little, and the type of shark that attacks innocent people for no reason is limited to only a very few types. Here we would like to introduce the true life of sharks through the individuals in "The Sea of Dangerous Sharks and a great variety of materials and artifacts, including real specimens.

A reconstructed model of the jaw of this extinct 16-meter long shark is now on display. Replica teeth have been fitted so you can feel just how big they were! Photography is permitted in the aquarium, so take a picture standing in the jaw to get an idea of how huge it was.

Fetal Specimens from a Great White Shark

Great White Shark reproduction takes place by what is known as "egg cannibalism", in which fetuses cannibalize their siblings in utero. Surviving fetuses grow by eating eggs ovulated by the mother in the uterus.
Various other shark specimens and models are on display.

Touch a Shark Skin!

In the center of the room, skins of sharks and rays are on display. Different species of shark have different skin surfaces. The skin of most shark species has a specific orientation. If you rub the skin from head to tail, it will feel smooth, but if you rub it in the opposite direction, you will feel resistance. Try it and see!

Unlike humans, sharks do not have permanent teeth. New teeth grow up periodically from within, and the old ones fall out naturally. If you look closely at the bottom of the dangerous shark tank, you will see some of the teeth that have fallen out strewn around the sand.
