They are deadly to their surroundings, but not because of their venomous spines, because of their hunger.

它们对周围环境来说是致命的，但这并不是因为它们有毒的刺，而是因为它们的饥饿。

Their venomous spines release a poison, which means pain for swimmers or divers who get too close, but their flesh isn't poisonous.

它们的毒刺会释放出毒素，这会给靠近的游泳者或潜水者带来痛苦，但它们的肉却无毒。
