We ’ve already looked at some of the most astonishing out species of sharkover here , now let ’s look at some you’re able to still encounter in our oceans .
There are over 470 mintage of shark swimming in Earth ’s oceans , but we tend to focalize most of our attending on about five of them . Here ’s some of the coolest , less known sjarks we ’ve pick up of .
1 . Megamouth shark

The name is pretty descriptive and gives us a good idea about this shark ’s unique feature article . The megamouth has a massive mouth , with thick gristly lips that give it an appearing unlike any other shark out there . In fact , it is so unique that it is sort in its own distinct family . It is part of the select group of planktivorous sharks that feeds mostly on plankton . Like its fellow members , the heavyweight shark and basking shark , it is a filter - eater .
In terms of size the megamouth gets pretty big like , but it ’s still modest compare to the other two species of filter - feeding shark . They develop around 13 - 16 ft ( 4 - 5 m ) and librate around 2,600 pound ( 1,200 kilogram ) . There is n’t much else to say about them because unfortunately , we recognize very little about them . They were only get word around 40 yr ago by chance and , since then , we ’ve encountered less than 60 specimens .
2 . Hammerhead shark
The hammerhead shark is quite well - known , but this does n’t detract from the fact that it is definitely one of the weird groups of sharks ( there are actually 11 specie of hammerhead ) . Again , its name is reasonably revelatory and it cite to the incredibly outre physical body of the shark ’s capitulum . It ’s been debated for a long clip why they have evolved to have that unequalled hammer - alike shape and it is broadly speaking agreed that it pay them improved imagination . shithead shark are capable of check what is below and above them at the same time , so the weird shape of their read/write head move over them 360 degree vision . The smashing hammerhead , the heavy species of the group , mature to a length of 15 ft ( 4.5 m ) and weigh up to 1,300 lb ( 600 kg ) .
3 . Greenland shark

Typically , we think of sharks of lightning - quick marauder who snipe in the blink of an eye . That is not the case with the Greenland shark . This guy swims around at a cruise speed of 1 mph ( 1.6 kmh ) or boring and when he gets the demand for speed he can get up to a blistering 1.6 mph ( 2 kmh ) . He is part of the family Somniosidae , also know as sleeper sharks , which are characterized by their slow move . However , even for that chemical group , the Greenland shark is a slowcoach as he is considered to be the slowest shark in the world .
These shark are obtain in the cold , rich waters surrounding Canada , Iceland and Greenland and we have very little information about them . From the few specimens we have catch up with , we see that the shark is big and can grow to size of it corresponding to the great white . One mystery we still have n’t solved is how this guy feeds . Stomach cognitive content that we analyzed included sealing wax and eels and other brute much faster than it , so we still do n’t roll in the hay how it captures its prey .
4 . Sawshark

Like the hammerhead , the sawshark is in reality a radical which is incorporate out of several specie of shark that share a very distinct process – an stretch snout with tooth on the side that they use like a leaf blade so as to capture and kill prey .
The sawshark often gets confused with the sawfish because the two are very like and both groups have the saw - alike snout . However , there are a few key differences since the sawshark is really a shark while the sawfish , although it looks very much like a shark , is actually a ray . First of all – size of it . The sawshark is really much smaller than the irradiation . The shark gets up to a size of it of 5.5 ft ( 1.7 m ) while the sawfish can grow up to 23 ft ( 7 m ) . Another difference is the snout – the sawshark has barbel on it ( long , whisker - similar antennae ) while the sawfish does n’t . Finally , like most shark , the sawshark has its gill possibility on the position while the ray has them on its underside .
5 . Cookiecutter shark

The cookiecutter shark has a silly name and a midget stature of 20 inches ( 50 curium ) . Despite this , he is one vicious predator you would not desire to mess with . This is because it preys on just about every large and medium - sized animal it shares an ocean with : whale , sharks , dolphin , seals , ray , dugongs etc . The way it does this is by latch on to a host through suction . Afterwards it sinks its teeth into the prey with the upper row dissemble like an anchor while the lower teeth start munch away . Then the shark begins twisting so that , in the end , it wring out a round clod of flesh , hence the name cookiecutter . Besides its parasitic feeding strategy , the cookiecutter shark has a bizarre cigar - shaped eubstance and it is also extremely bioluminescent to convince its prey to come up to it .
6 . Thresher Shark

The thrasher shark looks pretty normal aside from its absolutely monumental tail . count on the specie , the tail can get to be half its entire length which can be up to 20 ft ( 6 m ) in the causa of the uncouth thresher shark , the largest coinage in the radical . The low one is the oceanic thresher that only grows to 10 ft ( 3 m ) . The primary use of the buttocks is for catching prey . The shark would weave through schools of fish and tear its tail as it go . Afterwards , it would work around and catch the fish that have been daze by the tail .
7 . Frilled shark
With expression taken straights out of a horror movie , the frilly shark is much more evocative of an eel or a snake thanks to a long , thin body . It has a very primitive spirit , which is why it has long been consider a “ living fogy ” , an extant species which closely resemble nonextant mintage known only from fossils . However , the frilly shark itself is a relatively young species . The oldest fossil teeth we ’ve find were dated to the beginning of the Pleistocene epoch , 2.5 million years ago .
The name is derived from its six pairs of gill slits which are long and frilly . It is extremely unlikely that you will discover one of these guys as they are super rare and prefer to survive in the inscrutable ocean . Those that have been found have had a maximum length of 6.6 ft ( 2 m ) .
8 . Wobbegong Shark
The wobbegong shark is actually a group of carpeting shark comprised of 12 single specie . The name “ carpet sharks ” refer to an fiat of shark with colorful , flowery patterns on their back which can be remindful of a carpeting . In the case of wobbegongs , the radiation pattern are not mean to help them stand out or to draw in target , but rather to camouflage . Wobbegong sharks have a alimentation tactic which is actually quite strange for sharks : they lie in in wait at the bottom of the ocean and snatch up any quarry that comes too close . Completing the camouflage is a serial publication of lobe attached around the mouth of the shark which resemble weeds and avail entice fish . They can grow up to 10 ft ( 3 m ) in length , although most species measure less than half that .
9 . Zebra shark
The zebra shark is another specie of carpet shark who has unequalled convention on the top of its organic structure and , with a name like that , you would think that those pattern would be pretty obvious . However , you would be wrong because the zebra shark actually has small , morose place on a pallid background . It also has five quite obvious ridges break down the duration of its body . Surely , with a approach pattern like that , a more fitting name for it would be the leopard shark and , indeed , it is actually called that in certain places of the world . To make things even more puzzling , there is in reality another coinage of shark which is called leopard shark and it is completely unrelated .
So why “ zebra shark ” ? Well , because the name is actually more fitting for the young pups who take care completely dissimilar from the adults . They have white-hot vertical stripes on a dismal brown background and miss the ridges . The adults can grow up to 8 ft ( 2.5 m ) but they stay quite pop with divers because they are very docile and will give up mankind to get very close without attacking or running off .
10 . Goblin shark

The goblin shark is definitely not a looker . Luckily for it , the goblin shark does n’t need to look pretty since it ’s a bottom - dweller found in the sea depth . From the commencement , the most distinctive feature is its long protruding blade - corresponding snout . The size of the nozzle will really get small as the shark ages . It also has a pink body which is pretty strange but , by far , the most bizarre scene of this shark is its jaw – it has a protrusible jaw with sharp teeth which can be gallop outwards for catch prey . call up of the xenomorph in “ Alien ” and you ’re pretty close .
The average size of a goblin shark is between 10 and 13 ft ( 3 and 4 m ) and we do n’t really know much else about it . Like many other species of shark on this list , the goblin shark continue a mystery because it is hard to study . Although enquiry suggest that it is not a particularly rare creature , the goblin shark hold up mostly in areas which are untouched by man , so it is difficult to track it for long period of metre .
