What types of symptoms can a casualty display after being stung by a marine animal?

A casualty who has been stung by a marine animal can display a range of symptoms depending on the species of marine creature involved, the severity of the sting, and the individual's reaction. This includes skin irritation, which might manifest as a rash or discomfort at the site of the sting. Additionally, there can be varying degrees of pain, which is often described as severe, depending on the type of marine animal.

In some cases, the affected area may show slight redness as well, indicating inflammation or irritation. Therefore, the correct answer encompasses the possibility of experiencing both skin irritation and severe pain, as both symptoms can be indicative of the body’s reaction to the venom or irritants released from the sting. This comprehensive understanding helps inform appropriate first aid responses and medical interventions needed for someone who has suffered such an injury.
