Overview of marine bites and stings

[Sommer]

Some marine bites and stings are toxic, such as those inflicted by

Cnidaria (or coelenterates, such as jellyfish and sea anemones)
Mollusks
Sea urchins
Stingrays

All create wounds are at risk of infection with marine organisms, most notably Vibrio species, Aeromonas species, and Mycobacterium marinum.
Shark bites result in jagged lacerations with near-total or total amputations and should be treated in the same way as other major trauma (see Approach to the Trauma Patient : Evaluation and Treatment).
