21.01.2022 Although shark attacks can seem vicious and brutal, it's important to remember that sharks aren't evil creatures constantly on the lookout for humans to attack. They are animals obeying their instincts, like all other animals. As predators at the top of the ocean food chain, sharks are designed to hunt and eat large amounts of meat. A shark's diet consists of other sea creatures -- mainly fish, sea turtles, whales and sea lions and seals. Humans are not on the menu. In fact, ...humans don't provide enough high-fat meat for sharks, which need a lot of energy to power their large, muscular bodies. If sharks aren't interested in eating humans, why do they attack us? The first clue comes in the pattern that most shark attacks take. In the majority of recorded attacks, the shark bites the victim, hangs on for a few seconds (possibly dragging the victim through the water or under the surface), and then lets go. It is very rare for a shark to make repeated attacks and actually feed on a human victim. The shark is simply mistaking a human for something it usually eats. Once the shark gets a taste, it realizes that this isn't its usual food, and it lets go. The shark's confusion is easier to understand once we start to look at things from the shark's point of view. Many attack victims are surfers or people riding boogie boards. A shark swimming below sees a roughly oval shape with arms and legs dangling off, paddling along. This bears a close resemblance to a sea lion (the main prey of great white sharks) or a sea turtle (a common food for tiger sharks). See more

07.01.2022 What’s the most frequent diving injury? Decompression illness, right? No, it’s ear injuries. The most common injury divers experience is some form of barotrauma to the ear. Barotrauma means injury from pressure (baro = pressure + trauma = injury). This type of injury occurs for a variety of reasons, but generally it develops when the pressure in the middle ear is not equal to the pressure of the outside environment as the diver descends in the water column. (But see Barotraum...Continue reading
