Schools of Kobudai can also be found in residence, adding diversity to the underwater scene. Additionally, divers have the opportunity to witness the fascinating behavior of moss dippers, anemones, and other dippers, as well as observe the spawning rituals of spoonbills and octopuses.

Diving in Sado Island's waters provides a unique experience, enriched by two sunken vessels resting in the sand.
