| 背面描述 |
Nudibranchs are not typical hard-shelled molluscs that rely on a shell for protection. Instead, they use potent toxins that make any fish attempting to swallow a nudibranch quickly spit it out. Moreover, nudibranchs can even repurpose the defence mechanisms of the creatures they feed on, such as sea anemones. They harvest the highly venomous stinging cells from the polyps of these flower-like animals and store them for future use. When threatened, they unleash the ‘stolen’ stinging capsules to fend off their attacker. |
