10 Deadliest Sharks

I love love love the ocean! I wish that I could live there and go snorkeling everyday. The bright colors and smooth movements of the tropical fish have always fascinated me. There is so much life and diversity in the ocean - everything from soft-shelled sea turtles, shrimp, seahorses, dolphins, urchins, squid, jellyfish, starfish, sponges and plankton, clownfish, otters, to even seagulls. When I was little, when I grew up I wanted to be a killer whale trainer and swim with Shamu at Sea World (and still do!) If I could be any animal it would definitely be a killerwhale! I wish that Discovery had Whale Week, but they don't so Shark Week will have to do :) I love their programs... except when they talk about evolution, which is a lie!

Its a myth that you're safe in shallow water. 85% of shark attacks happen close to shore, with 2/3 of them in less than 5 feet of water. You're safest from a shark when its in tonic immobility; an upside-down shark acts like it has been hypnotized and becomes much calmer than normal.


10 Deadliest Sharks
#10 - Lemon Shark. They are sprinters - can swim 0 to 20mph in 2 seconds. They look a little different because they have 2 large dorsal fins instead of just one. They're also unique because they have eyelids - can hunt in daytime and at night.

#9 - Blue Shark. They are the tenacious shark - very stubborn and will travel far for food. The same blue shark was tagged then found over 3,000 miles away. Their body is more flexible than other sharks, so they don't get as tired when traveling long distances.

#8 - Hammer Head. They can turn on a dime. They feast in shallow, tropical bay water. Their unique head shape makes it stand out. Underneath their "T" shaped head they have lots of jelly-filled sensors to read electro-impulses to scan for fish/food movement.

#7 - Sand Tiger. They are unpredictable and known for being baby cannibals. They are the scariest looking - especially their slanted, needle like rows of teeth. When they are in the womb they eat the eggs of their brothers and sisters.

#6 - Grey Reef Shark. They are aggressive competitors. They feed in groups and it turns into a bloody frenzy. They're very territorial.

#5 - Mako. looks like a living torpedo. It's not large but it's built for speed - the world's fast shark at 30 mph/hour on average. They move faster because their body temp is 7-10 degrees warmer than the water. They are one of the only sharks that will eat other sharks.

#4 - Oceanic White-Tip. One of the most aggressive and efficient eaters. Have excellent sense of smell. Surprise, surprise their dorsal fin has a white tip.

# 3 - Tiger shark. They'll eat basically anything and everything. Two of their main foods are sea turtles and seagulls. The top lobe of their tail is also larger than the bottom. They have beautiful, spot-like markings - similar to a tiger.

#2 - The Great White. Jaws :) They're very picky eaters, usually prefer sea lions and seals. They feed in murky waters so many times they misinterpret a surfer on a surfboard as a seal. Because they're big and not very maneuverable they use the element of surprise - come from below. They crush & bite the victim then wait for them to bleed to death before eating them. They're in danger of extinction because they breed slowly.

#1 - Bull Shark. It will strike at anything it can with or without provocation. They're found everywhere, the only shark that can live in fresh water. They hang in shallow, murky water. They are even found in the Mississippi River, the Ganges and 2000 miles up the Amazon.


Did you know sharks deliver babies in live birth and in eggs. Mothers carry babies for 9 months. Their litters can be anywhere from 4-17 babies. After their born most mothers have nothing to do with raising their babies, not even the first feed. The babies are called pups.
