# Izu Mito Sea Paradise

The permanent displays hold about 300 kinds of fish, and the bay outside drops to 2,500 metres. A deep-sea tank comes with a touch pool where children can handle a giant spider crab. Jellyfish drift in a room of their own, and a walk-through enclosure puts you inside the penguins' living space. Dolphins and sea lions perform, and there are sessions to feed them or shake hands with an otter. Children's areas include an indoor sandpit and a pool where they play with fish.
