Answer 2

Answer:

Introduction :

Coastal waters around the world are dangerous for several reasons. Tides, currents, and rip tides pose a risk for drowning. Plants and animals can harm humans through accidental contact, self-defense, or attack. Animals can cause bite or puncture wounds and potentially deliver venom or toxin with fangs, spines, or stinging cells. The most common incidents are injuries from stony coral and sea urchins and stings from jellyfish, fire coral, stonefish, and sea anemones. Most dangerous are activities that lead to drowning, envenomation by box jellyfish, and attacks by sharks.
