Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the Batoidea (rays and kin). Some sources extend the term "shark" as an informal category including extinct members of Chondrichthyes (cartilaginous fish) with a shark-like morphology, such as hybodonts. Shark-like chondrichthyans such as Cladoselache and Doliodus first appeared in the Devonian Period (419–359 million years), though some fossilized chondrichthyan-like scales are as old as the Late Ordovician (458–444 million years ago).[1] The earliest confirmed modern sharks (selachimorphs) are known from the Early Jurassic around 200 million years ago, with the oldest known member being Agaleus, though records of true sharks may extend back as far as the Permian.[2]
Sharks range in size from the small dwarf lanternshark (Etmopterus perryi), a deep sea species that is only 17 centimetres (6.7 in) in length, to the whale shark (Rhincodon typus), the largest fish in the world, which reaches approximately 12 metres (40 ft) in length.[3] They are found in all seas and are common to depths up to 2,000 metres (6,600 ft). They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwater.[4] Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics. They have numerous sets of replaceable teeth.[5]
Several species are apex predators, which are organisms that are at the top of their food chain. Select examples include the tiger shark, blue shark, great white shark, mako shark, thresher shark, and hammerhead shark.
Sharks are caught by humans for shark meat or shark fin soup. Many shark populations are threatened by human activities. Since 1970, shark populations have been reduced by 71%, mostly from overfishing.[6]
It's early morning, the sun comes out
Last night was shaking and pretty loud
My cat is purring, it scratches my skin
So what is wrong with another sin?
The bitch is hungry, she needs to tell
So give her inches and feed her well
More days to come, new places to go
I've got to leave, it's time for a show
Here I am
Rock you like a hurricane
Here I am
Rock you like a hurricane
My body is burning, it starts to shout
Desire is coming, it breaks out loud
Lust is in cages 'til storm breaks loose
Just have to make it with someone I choose
The night is calling, I have to go
The wolf is hungry, he runs the show
He's licking his lips, he's ready to win
On the hunt tonight for love at first sting
Here I am
Rock you like a hurricane
(Are you ready, baby?)
Here I am
Rock you like a hurricane
Here I am
Rock you like a hurricane
Here I am
Rock you like a hurricane
Rock you like a hurricane
It's early morning, the sun comes out
Last night was shaking and pretty loud
My cat is purring, it scratched my skin
So what is wrong with another sin?
The night is calling, I have to go
The wolf is hungry, he runs the show
He's licking his lips, he's ready to win
On the hunt tonight for love at first sting
Here I am
Rock you like a hurricane
(Are you ready, baby?)
Here I am
Rock you like a hurricane
Here I am
Rock you like a hurricane
(Come on, come on, come on, come on)
Here I am
Rock you like a hurricane
Here I am
