How deep are most tetraodontiform fishes found?

Most tetraodontiform fishes are typically found in shallow waters, specifically at depths of less than approximately 65 metres (200 feet). They are particularly prominent in environments such as coral or rocky reefs, as well as on open sand and grass flats.1

While the majority of the order inhabits these shallower depths, there are exceptions. Members of the families Triacanthodidae and Triodontidae are notable for being deepwater species.21
