Each year, dozens of adventurous human diners (and an untold number of underwater gourmands) are stricken with puffer fish poisoning. But their bodies harbor a toxin 100 times more lethal than cyanide. Not venomous, mind you, they don’t bite or sting. Of the estimated 1,200 venomous fish species on Earth, the stonefish is the most lethal – with enough toxin to kill an adult human in under an hour. ![]() To humans, tetrodotoxin is deadly, 1,200 times more toxic than cyanide. Almost all pufferfishes contain tetrodotoxin, a substance that tastes fun to them and is often fatal to fish. What happens if you hold a puffer fish?Īre Puffer fish poisonous to touch or eat? Yes. Tiger sharks often eat pufferfish, as do other species of shark. Do puffer fish have enemies?ĭue to their toxicity, pufferfish have few natural predators. ![]() Poisonous puffers are believed to synthesize their deadly toxin from the bacteria in the animals they eat. Large specimens will even crack open and eat clams, mussels, and shellfish with their hard beaks. The diet of the pufferfish includes mostly invertebrates and algae. What type of fish do puffer fish eat?ĭiet. Human consumption is not recommended.Will a dog-face eat a sand-shiftin starfish, is there any starfish they wont eat? Unfortunately starfish are a big no with arothrons. Note: Like many Puffers, the Smooth Puffer is reputed to be highly poisonous, even fatal, if eaten, due to the potential presence of potent neurotoxins saxitoxin and/or tetrodotoxin, which is found in their skin, viscera, and gonads and is believed to protect them from predation by larger fish. They are caught primarily by deep water trawls and utilized on a very limited basis for human food by some cultures. The Smooth Puffer can easily be confused with the Oceanic Puffer, Lagocephalus lagocephalus (belly with spotting caudal fin with a longer lower lobe bicolored pectoral fins, dark above and white below juveniles with 9 bars).įrom a conservation perspective the Smooth Puffer is currently considered to be of Least Concern with stable, widely distributed populations. In Mexican waters they are found in the Atlantic Ocean including the Gulf of Mexico and the east coast of the Yucatán Peninsula in the Caribbean. The Smooth Puffer is a a wide ranging species found in all global tropical and subtropical waters. The Smooth Puffer is poorly studied with very limited information available about their lifestyle and behavioral patterns including specific details on age, growth, longevity, movement patterns, diet, habitat use, and reproduction. They reach a maximum of 1.00 m (3 feet 3 inches) in length and 4.9 kg (10 pounds 14 oz). The adults are pelagic and the juveniles are found on coastal and offshore banks. The Smooth Puffer is found as a solitary individual or in small groups inshore and near shore from the surface in both brackish and marine environments to depths up to 180 m (3,300 feet) over sand and mud substrate. They are covered with thick skin that is smooth to the touch except for small spines on the belly. Their pointed anal fin has 13 to 15 rays and is directly below the dorsal fin their caudal peduncle is slender their caudal fin is concave and symmetrical with lobes of equal length their single dorsal fin has 12 or 13 rays and has a short base and is found at the rear their pectoral fins have 17 or 18 rays and, they do not have pelvic fins. Their head has a long beak-like snout with a small projecting mouth equipped with four fused teeth with eyes set high on the sides. ![]() The juveniles and sub-adults have three or four dark saddles on the upper back. Their head and upper body are gray or gray-green dorsally that transitions to silvery on the sides and to white ventrally with uniformly colored fins. The Smooth Puffer has an elongated inflatable body. ![]() Globally, there are ten species in the genus Lagocephalus, of which two are found in Mexican waters, this species from the Atlantic and one that resides in both the Atlantic and Pacific. The Smooth Puffer, Lagocephalus laevigatus, is a member of the Puffer or Tetraodontidae Family, that is known in Mexico as botete grande.
