Similarly, why is a hammerhead shark's head shaped like that?
Hammerhead sharks are voracious predators and their mallet-shaped heads boost their ability to find that which they like to eat. The wide expanse of head allows for a broader spread of highly specialized sensory organs that they use to find food. And beyond smell and vision, these sensory organs are rather high-tech.
Also, what did hammerhead sharks evolve from? Further, the hammerheads seem to most closely resemble the carcharhinid Scoliodon laticaudus, also known as the Spadenose Shark. It had traditionally been thought that all the hammerheads evolved from a single carcharhinid ancestor with a 'normal-shaped' head.
Thereof, what do Hammerheads look like?
They are gray-brown to olive-green on top with off-white undersides, and they have heavily serrated, triangular teeth. Their extra-tall, pointed dorsal fins are easily identifiable. Most hammerhead species are fairly small and are considered harmless to humans.
Can hammerhead sharks see behind them?
By moving their head sideways as they swim, the sharks can see much of what is behind them. More extraordinary is that the position of the eyes allows the sharks to see through 360 degrees in the vertical plane, meaning the animals can see above and below them at all times.
