Final answer:
Divers are usually injured by harmful sea life because sea life mistakes divers for prey. It's important for divers to understand the behavior and habits of different sea life species they may encounter, and to take necessary precautions to minimize the risk of such incidents.
Step-by-step explanation:
Divers are usually injured by harmful sea life because sea life mistakes divers for prey. Some sea creatures, such as sharks, have difficulty distinguishing between a human diver and their usual prey due to similar movements or appearance. This can lead to accidental attacks and injuries.
For example, sharks may mistake a diver's silhouette from below with the shape and movements of a seal or other marine mammal, which are commonly found in their natural diet. Similarly, other sea creatures may perceive divers as potential prey due to sensory cues or territorial behavior.
It's important for divers to understand the behavior and habits of different sea life species they may encounter, and to take necessary precautions to minimize the risk of such incidents, such as avoiding areas known for dangerous sea life or using proper equipment and safety measures.
