The telson is used as a paddle when alarmed to put distance between crayfish and prey. The crayfish makes a rapid movement of its tail which helps it to move backwards swiftly.
no animal can walk backwards, they don't have legs!!
Use its tail to swim backwards at high velocity.
Lobsters are saltwater and crayfish (crawdads) are freshwater.
I live in New Rochelle, New York and I have recently seen many crayfish migrating away from Glenwood Lake and being killed by the dozens on an adjacent road. Why is this and where are they trying to go?
They are both invertebrates.
They are shellfish, they have an exoskeleton.
There is nothing different
It helps them maintain their balance under water, and allows them to swim backwards swiftly when frightened or running from predators.
A car model that is spelled the same forward and backwards is a race car. As you can see RACECAR backwards is RACECAR.
if your question is why does a dragon fly look like a crayfish? they don't look the same at all. the crayfish looks like a lobster but that is it.
A palindrome reads the same backwards, 8.48 backwards is 84.8 as they are not the same is can not be a palindrome.
