This species draws attention both as an invasive species threatening ecological balance and for the risks it poses to human health. #### **Taxonomy and Morphological Features** The [pufferfish](/en/detay/shimonoseki-fuku-3a670/llms.txt) belongs to the family *Tetraodontidae*. Scientifically named *Lagocephalus sceleratus*, it was first described by Gmelin in 1789. Its body is torpedo-shaped, with a gray-green dorsal side and a white belly. It has a distinct silvery stripe along its sides. The mouth is equipped with strong jaws and sharp teeth, enabling it to easily consume hard-shelled organisms. Adult individuals typically reach lengths of 50–60 cm, with some growing up to 100 cm. #### **Habitat and Geographic Distribution** The [pufferfish](/en/detay/balon-baligi-lagocephalus-sceleratus-71562/llms.txt) is naturally found in the Indo-Pacific region and the Red Sea. However, with the opening of the Suez Canal, it migrated to the Mediterranean and has rapidly spread there. It was first recorded in 2003 in Gökova Bay, Turkey. Currently, it is observed mainly along Turkey’s southern coasts as well as in parts of Greece, Cyprus, Israel, and Italy. This rapid spread is attributed to the species’ high adaptability and broad tolerance range. #### **Feeding Habits and Ecological Role** The pufferfish exhibits a generalist feeding strategy. Its diet includes crustaceans, mollusks, small fish, and even conspecifics. This wide dietary range facilitates its easy adaptation to new habitats. Moreover, thanks to its strong jaw structure, it can consume hard-shelled organisms. These traits enable the species to impact local food chains and compete with native species in the ecosystems it inhabits. ![Image](https://cdn.kureansiklopedi.com/media/uploads/2025/05/15/e2bjKREUDdbaacWhnC7YWWGnknCZa6OJ.jpg) *Blowfish Nutrition (Created by Artificial Intelligence)* #### **Reproductive Biology** The pufferfish's breeding season generally occurs from late spring to summer. During this period, females release planktonic eggs into the water. After hatching, the larvae complete their planktonic phase before transitioning to a benthic (bottom-dwelling) lifestyle. The species’ high reproductive capacity and rapid growth rate contribute to a swift increase in its population. ![Image](https://cdn.kureansiklopedi.com/media/uploads/2025/05/15/XtUe9dt98joLPoetvWRvYzablA6gIkpz.jpg) *Blowfish Reproduction (Created by Artificial Intelligence)* #### **Toxicity and Impact on Human Health** The pufferfish contains a potent neurotoxin called tetrodotoxin (TTX). This toxin is concentrated particularly in the liver, ovaries, skin, and muscle tissues. TTX affects the nervous system and can cause respiratory paralysis and death. For this reason, consumption of the pufferfish is banned in many countries. However, poisoning cases due to accidental consumption have been reported in some regions. #### **Economic and Ecological Effects** The spread of the pufferfish in the Mediterranean negatively impacts both the ecological balance and the fishing industry. The species competes with native fish species, reducing their populations. Additionally, its strong teeth cause damage to fishermen's nets and fishing lines. ***Warning: The content in this section is intended solely for general encyclopedic information.
