Despite being very little, these sharks have some of the most intriguing eggs in all of the animal kingdom.Long tendrils linked to a conical spiral on the egg of the rare crested bullhead shark are utilized to secure the egg to surrounding sponges or seaweed.
The shark at Port Jackson also has a pig-like face.Mackerel sharks belong to the Lamniform family.The great white shark is the most well-known member of this order, but it also includes its bizarre deep-sea relative,the goblin shark,which is remarkably adept at hyperextending its jaw when feeding.
This list also includes basking sharks,the second-largest fish in the world (after whale sharks).Then there are the Orectolobiformes, which includes wobbegongs and carpet sharks.
The wobbegongs are very amazing since they resemble swimming shag rugs and have frilly beards and patterns on their spectacles to help them blend in.The commercial fishing industry poses a serious threat to these bottom-dwelling, nocturnal sharks.Their diminutive size meansThey frequently get ensnared in lobster traps and swept up in nets.Squatiniformes, also referred to as angel sharks,have a hybrid appearance between a shark and a ray.
Most often, they resemble the result of running a shark underneath a rolling pin.
They spend their time flat on the ocean floor, covered in a thin coating of dirt, and are masters of camouflage.
waiting for a fish or squid to swim by unnoticed before striking.The sawfish, or Pristiformes, are more closely related to rays than the sawsharks,which are classified as Pristiophoriformes.they're all still sharks, though.
These two orders are different in several respects, including:Sawfish, which stay in coastal areas and have gills on the underside of their bodies, are smaller than sawsharks.
as opposed to sawsharks, which have side gills.And when I say that sawfish can get big, I really mean mythically big.This is the rostrum of a single creature, and it is covered in sensory pores that enable it to detect electrical impulses as it forages through the muddy ocean bottoms.
Let's finally discuss the other skate and ray orders.The skates are rajiformes.
The devilfish and the atypically formed and appropriately called guitarfish are two species that are easily recognized from this group.
Or, you might have something that falls somewhere in the middle, like this person, who is actually a guitarfish that was altered to resemble a devil child and then offered for sale as a tourist attraction in
Mexico in the 1950s.
It's not a baby of the devil.The stingrays, or Myliobatiformes, are next; they got their name from the poisonous barb at the end of their tails.
Usually, a defense is only used when someone steps on them or otherwise harasses them.The enormous oceanic manta ray is one noteworthy member of this order without a stinger.
This is so enormous that it has smashed records. The largest one ever measured measured 30 feet (9 meters) wide.
Consider swimming close to a three-story structure.Torpediniformes, electric rays, and numbfishes round out this list of the twelve orders of sharks.
These animals' electrogenic nature is one of their most distinctive traits, though perhaps their name already gave that away.
They can send out signals to find species in murky water by storing energy in modified muscle fibers.
Alternatively, use it to stun surrounding predators to prevent attacks.
Large electric rays have a shock potential of
roughly 500 volts.Although it is insufficient to actually murder a person, it is sufficient to send a very powerful message.
I hope you'll spend some time looking into the hundreds of different species we didn't even cover today now that you're familiar with all twelve orders of sharks.
Or, have a look at one of our additional movies from the five days in a row that we focused on predatory cartilaginous fishes!
