Did you know…

The underwater world is such a fascinating place and we know so little about it. Every day we learn more and new things about the place we so love to go and visit while diving. Lets unravel some of the ocean’s secrets and let you in on our know how of fun and interesting facts of the amazing things we see.

When in the Caribbean, even more so then at home it is important to stay hydrated, well it appears that even fish need to drink. Saltwater fish need to drink more than their relatives the freshwater fish. Because seawater contains more salt than the fluids in a fish’s body, water inside the fish is constantly flowing out. If they don’t keep on drinking more water, saltwater fish would dry up like prunes.

People often ask us how we saw that fish, it was so camouflaged. Fish are amazing in camouflaging themselves and that is because most fish can see in color and therefore use colors to camouflage and blend in to defend themselves and their territory. Fish have the best possible eyesight for their habitat, some of them can even see polarized or ultraviolet light.

Parrot fish CocoonOne of our favorite things to do when we guide divers is hand them a bag of what looks like Parrot fishslime. When we get back on board of course everyone wants to know what the slimy stuff they touched was. That is parrot fish cocoon. At night, parrot fish build this bubble and wrap it around their body, so other marine life and mainly predators can’t sense them. When they wake up in the morning they swim out of their bubble and just leave this ball of slime behind. Often when swimming along near the reef, you can hear and see these guys biting of bits of coral. Later, you will most likely see them expel the chunks of coral.

PufferfishEveryone loves puffer fish and of course wants to see them puffed up. Even though it seems like fun, it is not a good idea. Experiments show that the puffer fish gets so tired from repeated puffing, that they can’t puff again after three to eight times in a row. Little do people know that this cute and silly puffer fish can be deadly. They carry enough toxin to kill 30 people.

“That lobster was massive, the biggest one I ever saw! How big was it? It must be so old!” It is always hard to tell exactlyLobster how big a lobster is under the water, but a typical lobster weighs 1 to 2 pounds. Studies show that a one pound lobster is 5 to 7 years old. Lobsters molt as they grow. Often we find their exoskeleton lying around on the ocean floor, which doesn’t mean they got eaten. It just means they changed their skin for another one. They do this pretty often; the average lobster can molt 44 times before it is one year old, but by the age of 7 it will only molt one a year and after that only once every 2 to 3 years. Lobsters are rumored to be immortal. That is not entirely true, but they will keep on growing until they get killed, either by humans or natural causes

Who does not want to see a sea turtle while diving? No matter how many you see, they remain amazing! You will often find them on the surface as they have to come up to breathe every few minutes. When they are resting, they can stay under for up to 2 hours without breathing. This does depend on where, what and who of course.

Sharks are very fascinating fish and we love seeing them. Speaking of seeing, their eyes is one of the most amazing thing of the shark. Sharks are the only fish that have eyelids and the only fish that can blink with both eyes. They can see almost as good behind as they can see forward. They have some of the best night vision.

The underwater world is what we so love and enjoy seeing the more you get to know about it, the more interesting it gets. If you know of some interesting facts yourself, be sure to let us know!
