🔬 物种简介
棘冠河豚受到威胁时会吞水膨胀成球状，同时全身尖刺竖起，让掠食者无从下口。皮肤和内脏含有河豚毒素，致命且无解药。尽管外形似笑脸，却极其可爱，是珊瑚礁潜水者最受欢迎的观察对象。
Wikipedia
Porcupinefishes are medium-to-large fish belonging to the family Diodontidae from the order Tetraodontiformes which are also commonly called blowfishes and, sometimes, balloonfishes and globefishes. The family includes about 18 species. They are sometimes collectively called pufferfishes, not to be confused with the morphologically similar and closely related Tetraodontidae, which are more commonly given this name.
