Lamnidae

Megalodon , meaning "big tooth," is an extinct species of shark that lived approximately 23 to 2.6 million years ago (mya), during the Early Miocene to the end of the Pliocene. There has been some debate regarding the taxonomy of megalodon: some researchers argued that it was of the family Lamnidae and closely related to the great white shark, while others argued that it belonged to the extinct family Otodontidae; presently, there is consensus that the latter view is correct. Its genus placement, however, is still debated, with authors placing it in either Carcharocles, Megaselachus, Otodus, or Procarcharodon. The shark has made appearances in several media, such as the Discovery Channel's docufiction Megalodon: The Monster Shark Lives. Scientists…

Sharks scientific name/ species name is the Carcharodon Carcharias. The Great White Shark is dominant depending on size and sex. Females are normally larger, so they are dominant to male Great Whites. Female Great Whites are normally pregnant for 12-18 months and they give birth to 3-14 5 foot long, live pups at a time. The pups are immediately left to fend for themselves. The Great White shark pups are in an egg, but the egg is hatched inside of the mother and the pups are kept inside of the…

wide geographic range. They can be found in all cold, temperate, and tropical waters. They can be found along the California coast all the way to the cape of South Africa. They are not common in any particular area, and they are becoming harder and harder to find. Great sharks travel long distances, which contributes to their geographic range. They first appeared 60 million years ago in the Paleocene seas of southern Russia, Morocco, Angola, and the United States. When it comes to taxonomy…

Kingdom: Animalia. Essentially all animals that have ever existed fall under Animalia. Phylum: Chordata. Organisms that have at least at some stage of development a notochord (a supportive rod-like structure made from cartilage), a central nervous system located in the back, and openings for water to pass over the gills. Class: Chondrichthyes. Jawed fish with paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage (rather than bone). Order: Lamniformes.…

The Dream Sea Imagine a sea where the sharks are the leaders. They boss in almost everything, however, to limit their powers, there are also other two groups of leaders: the whales, which judge all fishes' and sharks´ acts as right, wrong, fair or unfair, and the turtles, which are the wisest; they are responsible for determining the ideals of every habitant of the ocean. The three groups can limit the powers of one another, and the sharks are chosen by the population. In this…

Most people wouldn't dare to get into shark infested water, let alone cageless, in open water known as “Tiger(shark) Beach” and certainly not without prior shark dive experience...but Glen Hodges defied the majority by doing exactly so. Tiger sharks, “the species responsible for more recorded attacks on humans than any shark except the great white” (88) fill the open water of Tiger Beach and Hodges planned to get up close and personal with them during his dives to see in fact how dangerous this…

Squids and Octopuses are two very similar and incredible sea creatures who have lived on this earth for millions of years. Squids have gone down in history as fierce predators who are known to have taken down mighty predators like sharks as well as ships, in the 1700’s, giving them the description of giant sea creatures called Krakens. Octopuses have been known as great escape artists, with the ability to squeeze through smallest holes and crevices to escape predators at any given time. Both of…

Phylogeny of Sphyrna- Hammerhead Sharks INTRODUCTION I will be investigating the phylogenetic history of Sphyrna, a genus of hammerhead sharks. The eight species that fall under this genus are Sphyrna corona (scalloped bonnethead), Sphyrna gilberti (Carolina hammerhead), Sphyrna lewini (scalloped hammerhead), Sphyrna media (scoophead), Sphyrna mokarran (great hammerhead), Sphyrna tiburo (bonnethead), Sphyrna tudes (smalleye hammerhead), and Sphyrna zygaena (smooth hammerhead). Hammerhead sharks…

Sharks… They’re ferocious, aggressive, scary and interesting. Recently, few of today’s news tackle on shark attacks, discovery of shark species, or articles about Katy Perry’s shark back up dancers. Maybe, the sharks felt that we celebrated Shark Week, so they should be doing something to call our attention. Or maybe they’re just playing us? Hmm.. https://www.linkedin.com/pulse/im-proud-my-backup-aaron-harris?trk=mp-reader-card Sharks are usually found in the depths of the ocean and seas.…

Red-tailed black sharks or Epalzeorhynchus bicolor belong to the family Cyprinidae. This family of fish is also known as Cyprinids. In laymen's term the red-tail is a member of the carp family. The red-tailed black shark was native to Thailand. But sadly, they are now extinct in the wild. All the red-tails available in fish stores today are commercially raised products of the aquarium trade industry. Red-tails black sharks of course bear no relation to sharks. Their name is purely descriptive.…
