Even though white sharks frequent the waters around the entrances of Tomales Bay and Drakes Estero, the odds of being attacked by one are exceedingly remote. Still, it's best not to tempt them.
White sharks are rare visitors to coastal California, and when they do come ashore it is usually for food. They will search out large fish such as marlin and tuna and eat them when they can find them. However, these powerful predators often need help doing this. For this reason, boat strikes may provide an opportunity for white shark sightings. If you see a white shark while boating, stay in control of your vessel and keep your arms inside the wheelhouse at all times. Do not be alarmed if the shark follows your boat.
While white sharks are rarely aggressive toward humans, they will use their massive teeth as a form of communication by opening and closing them in order to let others know who is boss. If threatened, a white shark will often back down rather than fight.
There have been unconfirmed reports of dead white sharks being found in coastal California, probably fed upon by larger fish. These attacks are unlikely to happen again given the current lack of exposure for white sharks to humans.
More than one-third of all white shark attacks along our coast have occurred in the area encompassed by Big Sur to the south, the Farallon Islands to the west, and Point Arena to the north. The best strategy to avoid a shark encounter is to avoid high-risk areas and seasons, according to the study's authors. Sharks are most likely to attack during dark, cold months.
Sharks are fish too; therefore they need food, just like other fish. So when large numbers of prey items are available, then chances are there will be more predators. This is why summertime sightings of sharks are rare; there aren't that many fish around to be eaten by sharks. Wintertime sightings are more common because it's when their main source of food (such as squid) come back to shore. Also worth mentioning is that sharks are less active at night; so if you do see one, it's probably not a threat.
If you are in danger, play dead. If you are playing dead, make sure not to float up showing your neck, as this may provoke an attack.
Sharks are very sensitive to vibrations from fishing lines and boats. If you come across one off the beach, keep away from it until someone knows what type of shark it is and how dangerous it might be.
Shark bites are rarely fatal but they can lead to infections if not treated quickly.
"We've had a lot of sightings of white sharks in the region," one surfer explained. Shark attacks are quite infrequent in Puerto Rico. According to the Florida Museum of Natural History, only seven assaults have ever been documented, two of which were deadly, with the latest fatality being in 1924. The others occurred in 1916, 1873, 1835, 1713, 1580, and 1466 years ago.
Sharks are fish too, and like other fish they tend to avoid human contact. However, if forced into a conflict zone such as a boat or a surfboard, they will attack to protect their territory or prey. Because shark attacks are so rare, people often assume that they must be illegal or dangerous, but this is not true. They simply mean business and will not hesitate to strike if threatened.
The best way to avoid a shark attack is by not getting into these situations in the first place. If you find yourself in need of rescue, call for help instead of trying to swim away. Also keep quiet and still if you encounter one of these powerful predators; it may be afraid of humans.
Puerto Rico is a large island full of surprises, but no matter what you do, don't go swimming with sharks!
Sharks with white tips They seldom visit the bay of Puerto Vallarta because they prefer the deeper and colder waters further out. Whitetip sharks are more aggressive than nurse sharks and have a nasty reputation for preying on airline and shipwreck victims. They may grow to 20 feet (6 m) long and weigh up to 1150 pounds (521 kg).
There have been reports of great white sharks off the coast of Mexico, but none that we know of in the bays of Puerto Vallarta. The only reason this rumor has spread is because great whites are seen occasionally in Mexican waters, and these sightings have been reported in the press. Usually, if great whites are found in Mexican waters they are near shore in shallow water or around fishing boats, so they aren't likely to attack humans.
Here's what you need to know: Great white sharks are found worldwide in all kinds of water bodies, including oceans, lakes, rivers, and even the shallow parts of large bays. They are most common in cold waters from polar regions south of Europe and north of South America. Although great whites rarely attack people, they will defend themselves if threatened. That said, the only way to be attacked by a great white shark is if you put yourself in such a situation.
