Lagocephalus

Lagocephalus is a genus of marine fish in the family Tetraodontidae, commonly known as pufferfish. These fish are characterized by their ability to inflate their bodies with water or air, making them appear much larger and more unappealing to predators. This defense mechanism is a key feature of the genus.

The species within Lagocephalus are found in tropical and subtropical waters worldwide, inhabiting both coastal areas and the open ocean. They are often associated with coral reefs, seagrass beds, and sandy bottoms. Their diet typically consists of invertebrates, such as mollusks, crustaceans, and sea urchins, though some species may also consume algae.

Many species of Lagocephalus contain tetrodotoxin, a potent neurotoxin that can be lethal if ingested. This toxin is concentrated in certain organs, such as the liver and ovaries, and its presence makes these fish dangerous to consume. Despite the toxicity, some species are considered a delicacy in certain cultures, requiring specialized preparation to remove the poisonous parts.

Lagocephalus species exhibit a range of sizes, with adults typically measuring between 10 and 50 centimeters in length. Their coloration varies, often featuring intricate patterns and markings that can aid in camouflage. Reproduction generally involves external fertilization, with eggs laid in clutches. The genus is an important part of marine ecosystems, playing a role in the food web.
