What is special about the mako shark?
With top speeds of 45 miles per hour (74 kilometers per hour), the shortfin mako is the fastest shark and is one of the fastest fishes on the planet. This species’ athleticism is not restricted to its swimming speeds.
What sharks have bladders?
All sharks are slightly negatively buoyant, which means they sink. Unlike many bony fishes, sharks do not have a swim bladder to provide buoyancy.
What color is shark poop?
The plume appears yellow In the video, but Dove suspects the seawater is distorting the color. Shark poop is actually closer to green, Dove said.
Do all fish urinate through their skin?
A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills. When a fish pees in a coral reef, the corals wave their tentacles around like tiny arms to grab nutrients from the pee and absorb them.
What does shark poop smell like?
Add some digestive juices into the mix, and you’re left with what has been described as “an unholy mingling of fart and fishiness“, much like the smell produced by whale breath. Interestingly, whale sharks don’t always fully digest their meals.

Sharks do not sleep like humans do, but instead have active and restful periods.
How do sharks sleep if they can’t stop swimming?
So, we’ve established that sharks do sleep, although it’s more of a restful period than a truly deep sleep. Sharks with spiracles can rest on the sea floor to sleep while their spiracles continue to push water over their gills. This means that they can rest without having to worry about swimming to breathe.
Do sharks really smell blood?
Sharks can smell blood from hundreds of meters away—in concentrations as low as one part per million (ppm).
What happens if a shark swims backwards?
In the event a shark wishes to tilt backwards, it depends on gravity to fall rearward. Any backward movement by shark lets waters into their gills hence interfering with the respiratory process leading to death.
What is the smartest shark?
I’d argue Great White Sharks are the smartest species, they have body language they use to communicate to each other. They spy hop to look for seals and can recognise the sound of Orcas.
Has a mako shark ever killed a human?
ISAF statistics records 9 shortfin attacks on humans between 1580 and 2022, three of which were fatal, along with 20 boat attacks. This mako is regularly blamed for attacks on humans and, due to its speed, power, and size, it is certainly capable of injuring and killing people.
Are mako sharks color blind?
Ten species tested had no color-sensing cells, while seven had only one type. Sharks may be able to smell blood from miles away, but they probably don’t know how red it is: New research suggests sharks are color-blind.
Why doesn’t a shark have a swim bladder?
First, sharks lack the swim bladder that most fish use to adjust their buoyancy. Swimming creates lift that prevents sharks from sinking, using much the same principle that a wing uses to lift an airplane.
Do sharks ever stop moving?
Myth #1: Sharks Must Swim Constantly, or They Die
Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills, but others are able to pass water through their respiratory system by a pumping motion of their pharynx. This allows them to rest on the sea floor and still breathe.
