■ General characteristics
Also called “Balloon Fish”, the pufferfish’s most notable feature is its ability to inflate its body when it feels threatened. This is a defense mechanism that scares predators with the sudden change in size.
If the predator attacks it anyway, this fish has one of the most powerful poisons in the animal world. A small amount is capable of killing even a human being. Therefore, it is essential to remove all poisonous parts of the fish before preparing it for consumption.
There are around 125 species discovered to date, two of which are very present in Brazil, these are: Colomesus asellus, which inhabits fresh water and can reach up to 12 centimeters; and Colomesus Psittacus, which inhabits both river and sea water, and grows up to 30 centimeters. Below there are still a multitude of facts and curiosities about the pufferfish to discover!
■ Puffer fish reproduction
Pufferfish reproduction takes place during the flood season, between the months of September and January. After being fertilized, the female releases 3 to 7 eggs, which float to the surface and hatch within a week. The babies then finish their development and go deeper to meet other pufferfish.
There are also species in which the male takes care of the young. When they hatch, the fry leave the eggs and remain in a cavity that is guarded by the male, this condition lasts for about one or two weeks. After this, the male leaves the area and the cubs go out to sea.
■ Food
Puffer fish are omnivores, meaning it is no exaggeration to say that they eat everything. With a quick search you can find videos of this fish eating everything from frogs to centipedes or crabs. This is mainly because of their teeth, which are fully capable of chewing hard things. In its natural habitat, the pufferfish usually feeds on molluscs, crustaceans and other invertebrates, but in addition it feeds on plants and even detritus.
When in captivity, they may refuse dry food. Instead, live or frozen food should be provided. Furthermore, it is recommended to regularly give snails, hard-shelled shellfish or even calcareous sand so that the pufferfish can use up its teeth, as they are always growing and can cause problems for the fish if they become too big.
■ Habitats
Pufferfish inhabit waters all over the world, staying away from only the coldest ones, close to the poles. Being a pelagic fish, that is, it does not need the bottom of the oceans to survive, it usually inhabits depths of up to 300 meters, preferring above all to be close to reefs.
In Brazil, the species popularly known as “Amazon Puffer” inhabits the Amazon basin. The “Papagaio Puffer”, which is a saltwater species, can be found all along the national coast.

The first step is to throw bait into the water (it is recommended to use dead shrimp or another animal that is part of the fish’s diet), the strong smell of prey will attract them closer. Next, you must lower your line into the area where the baits are, and keep it firmly tensioned, this will increase sensitivity to bites, and you will feel it if the pufferfish bites your bait.
When you feel the bite, you should give a gentle jerk to secure the hook in the fish’s mouth. This moment is extremely important, as pufferfish are excellent at stealing bait, so the attack must be quick, so that it does not escape.
Having hooked the pufferfish, pull it towards you. He shouldn’t offer much resistance since he doesn’t swim very well. Once out of the water, use gloves to catch it, this way you prevent all types of contact with the fish’s skin, as this is one of the places where the dangerous toxin is present.
