Which shallow-water habitats commonly contain tetraodontiform fishes?

Most tetraodontiform fishes are found in shallow waters, typically at depths of less than 65 meters (200 feet). Within these coastal environments, they are especially prominent in the following habitats:1

• Coral or rocky reefs: These structures provide essential cover and foraging grounds for many species.1
• Open sand and grass flats: These areas are common environments for various members of the order.1
• Estuaries: Some shallow-water groups, such as the Triacanthidae (triple spines), may occasionally be found in these coastal transition zones.2

While most members of the order occupy these shallow regions, it is important to note that certain primitive families, such as the Triacanthodidae and Triodontidae, are exceptions that inhabit deeper waters.312
