Introduction


An envenomation is the process by which a venom or toxin is injected
into another being via a bite, puncture or sting. Envenomation is
always due to direct contact with an animal (or parts of it like drifting
jellyfish tentacles). There are two possible mechanisms of injection:
active, such as jellyfish or cone snails, or passive like lionfish or
sea urchins. Injuries typically occur during shore entries or exits,
incidental contact or deliberate attempts to handle a specimen.
Envenomations are rare but can be life threatening and may require
rapid first aid response. In this chapter, we will cover some common
envenomations as well as some of the more rare, but serious cases.
