What specialized structure do some coral species possess for toxin injection?
Answer
Nematocysts
Certain coral species possess specialized stinging cells known as nematocysts. These structures are designed to inject toxins upon contact with skin. This is separate from the mechanical injury caused by the sharp skeleton. For example, Fire Coral, which is technically a hydrozoan and not a true stony coral, causes envenomation characterized by immediate burning upon contact due to the activation of these stinging cells. The overall severity of a coral encounter depends on several factors, including the amount of toxin released from these cells, the size of the injury sustained, and the individual's inherent sensitivity to marine substances.
