The stingers (nematocysts) are released when they come in contact with flesh. Somehow there is recognition. When you poke your finger into a sea
anemone it will 'stick' to you but a rock will remain untouched. Although, some anemones will hold on to shell fragments to mitigate the effects of
the scouring waves. Moving shrimp will also release their weapons. These animals are more complicated than they seem.
Having said all that - if your dog gets stung on the nose he's gonna know it. |
