Which animal can't walk back?Kangaroos. Kangaroos are well known as large, hopping mammals from Australia that carry their offspring in pouches. What may not be so well known, though, is that kangaroos cannot walk backwards. Their hopping movement is called saltation.
Can a shark go backwards?Can Sharks swim backward? Unlike fish, sharks cannot stop suddenly or swim backward. A shark's pectoral fins cannot bend upwards like a fish, limiting its swimming ability to forward motion. If a shark needs to move backward, it uses gravity to fall, not swim backwards.
Do Sharks ever go backwards?Due to the shape of their fins, sharks can't swim backward. Sharks cannot swim backward, courtesy of the shape of their fins, which prevents them from stirring up sediment while swimming and makes it difficult for them to slow down as they approach the seafloor.
What happens if you flip a shark upside down?When the shark is gently turned on their back, it's thought to disorientate them, causing them to enter the state.

Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids.
What happens if you pull a shark by its tail?Moving forward: Sharks are the only fish that can't swim backwards — and if you pull a shark backward by its tail, it will die.
Can shrimp swim backwards?Unlike fish, shrimp do not have fins that enable them to swim, but they can certainly move around in the water. A shrimp "swims" by quickly pulling its abdomen in toward its carapace (body). This motion shoots them through the water.
