overview

who is the marbled puffer

Pufferfish of the family Tetraodontidae, reaching 20 cm. It lives on soft bottoms of the shelf, usually between 18 and 100 m deep. It occurs in the western Atlantic, from North Carolina, USA, to Suriname, including the Caribbean, and there are also records from Brazil. In Latin America it appears in Brazil, Colombia, Venezuela, Cuba and Nicaragua. Like other pufferfish, it has teeth fused into strong plates. It has a commercial fishery and is rarely caught on a rod.

Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the marbled puffer; in the meantime, see the similar species.

how to recognize it

identification

Short, deep body, typical of soft-bottom pufferfish, with the marbled pattern that gives the species its name. Like the whole family Tetraodontidae, it has teeth fused into plates that form a strong beak, and its body inflates when the fish feels threatened. To tell it apart from Sphoeroides pachygaster, check the depth: that one lives between 50 and 250 m, while this species generally lives at 18 to 100 m, over soft bottoms.

what the law says

rules for the marbled puffer

Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Not on the Brazilian national list (Ministerial Ordinance GM/MMA No. 1.667/2026).

We found no species-specific rule beyond the region's general rules.

catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.

When hooked, it tends to inflate its body, so keep it in the water until you remove the hook carefully. Like other pufferfish, it can carry toxin in the flesh and organs: do not take it home to eat.
