ไม่จริงครับ มีการศึกษาทางวิชาการแล้วว่าไม่จำกัดจำนวนครั้งในการที่มันจะพองลมครับ Is it true that the Pufferfish dies after inflating twice? Puffer fish inflation is a defensive measure, and as such, there is no limit to the number of times an individual can inflate (and deflate). If the fish is inflated on the surface, it is likely to ingest air. The air can be difficult to expel and can cause the death of the fish, since the fish floats and can not leave the surface. However, if the fish is inflated under water, it only ingests water and has no problem deflating once the danger has passed.
