10 Facts About Megalodon

Not only was Megalodon the biggest prehistoric shark that ever lived; it was the largest predatory marine creature in the history of the planet, outweighing both modern Great White Sharks and ancient reptiles like Liopleurodon and Kronosaurus. Here are 10 facts you may or may not have known about this lethal predator.

 














1. Megalodon's teeth were about 7 inches long...
Megalodon didn't earn its name ("giant tooth") for nothing. The teeth of this prehistoric shark were over half a foot long, serrated, and heart-shaped (by comparison, the biggest teeth of a Great White Shark are only about three inches long). You have to go back 65 million years--to none other than Tyrannosaurus Rex--to find a creature with consistently bigger choppers, though the canines of some saber-toothed cats also measured up.

Atlantic Blue Crab

 

Atlantic Blue Crab | The Chesapeake and Atlantic blue crab is a crustacean found in the waters of the western Atlantic, the Pacific coast of Central America and the Gulf of Mexico. Its Latin name, Callinectes sapidus (from the Greek calli = "beautiful", nectes = "swimmer", and Latin sapidus = "savory"). On the Pacific coast of Central America, Atlantic blue crab was largely ignored as a source of food and choosing the meat is considered too difficult. It is the Maryland state crustacean and the subject of an extensive fishery.

Mangrove Horseshoe Crab

 

Mangrove Horseshoe Crab | The Mangrove horseshoe crab is a marine chelicerate arthropod. Despite its name, it is more closely related to spiders and scorpions (all in the subphylum Chelicerata) than to crab. It is the only species in the genus Carcinoscorpius. These Mangrove horseshoe crabs can be found in the entire Asia Pacific region in shallow waters with a soft, sandy soils or extensive mudflats. The Mangrove horseshoe crab is benthopelagic, most of his life close to or at the bottom of a body of their brackish, swampy water habitats such as mangroves.

Japanese Spider crab

Some Coral Butterflies (genus Heniochus) closely resemble the Moorish idol. It is closely related to, if not a direct descendant of the extinct Eozanclus brevirhostris, from the Middle Eocene of Monte Bolca.

While not directly harm their hosts remoras (apart from sore skin, which is connected), manta rays do use more energy when swimming with them. There are few places more awe inspiring for divers than watching manta rays performing their graceful somersaults. These beautiful animals are often seen feeding alone or in small groups near the surface at Thailand dive sites such as Koh Bon, Komodo in Indonesia, Maldives, Myanmar in Blackrock, Kadavu in Fiji, and other near shore waters with coral rocky reefs and scuba.

Clown Triggerfish

 

Clown Triggerfish | The Clown triggerfish is triggerfish from the order Tetraodontiformes. This reef-associated fish is commonly found in the tropical Indo-Pacific. Clown triggerfish are one of the most colorful fish meet in diving and a great opportunity for pictures.

It is usually found on reef flats and slopes along the upper ocean. He lives alone or in combinations which together form large feeding.

Rainbow Parrot Fish

 

Rainbow Parrot Fish | Parrot fish named for their calcareous bird-like beak. Parrot fish use these beaks to crush and eat the small invertebrates that live in coral. Much of the sand and the sea floor of coral reefs are actually remains of meals from the Parrot fish, coral chew it, eat the invertebrates and spit out the remaining calcium. In most species, the first phase is dull red, brown or gray, while the terminal phase is vivid green or blue with bright pink or yellow spots. The remarkably different terminal and the first phases were first described as distinct species in some cases, but there are some species where the phases are similar.

Ballonn Fish
