Longspine Porcupinefish
Diodon holocanthus
Key differences: Diodon holocanthus has longer, erectile spines that lie flat against the body when not inflated, whereas Chilomycterus reticulatus has shorter, fixed, immovable spines that are always erect. D. holocanthus also typically has larger, more prominent spots and often a dark band between the eyes.
Balloonfish
Diodon sp. (e.g., Diodon holocanthus)
Key differences: Similar to the Longspine Porcupinefish, the Balloonfish (a common name for Diodon holocanthus) is distinguished by its erectile spines. The Spotfin Burrfish's spines are always erect and shorter.
Striped Burrfish
Chilomycterus schoepfi
Key differences: Chilomycterus schoepfi (found in the Western Atlantic) has a distinct pattern of dark, wavy stripes or reticulations on its body, rather than the discrete spots seen on C. reticulatus. Its spines are also fixed and short, but the body pattern is the primary differentiator.
