facts about crayfish

The Largest Crayfish in the World

The Tasmanian giant freshwater crayfish, also known as Astacopsis gouldi, is the friggin’ largest freshwater cray in the entire world.

These guys are only found in Northern Tasmania and are actually on the endangered species list. So if you see one, don’t pick him up. Just keep walking!

Crayfish Urinate to Attract a Mate

Yes, this is true. Crayfish literally urinate to try and attract a mate. It seems like the whole p*eing thing would have potential mates running the other way, but it must work for crayfish. No appetizers, no drinks, just p*e (don’t try this yourself).

Crayfish Will Eat Each Other
Crayfish are super aggressive. They are omnivores. And let me just tell you, these little guys will eat each other if they can. I learned this the hard way.

When I first got started with pet crayfish, I kept a white crayfish and a blue crayfish in a 10-gallon tank. And well, that was a mistake. After work one day, I came home, and there was just one white crayfish with a very blue tint.

Cancer lives for about twenty years. Does not tolerate dirty water. He cannot live in a clogged, dirty pond. The extinction of these arthropods is associated with unreasonable human activity, which allows chemicals to enter water bodies.

Crayfish belongs to decapod crustaceans. From the two front pairs of legs, claws (large and small) were formed. Cancer uses the remaining three pairs of limbs for movement. He moves quite original, rearing. In case of danger, he makes sharp movements with his tail, raises a cloud of mud from the muddy bottom, disguises himself in it, and tries to hide.

Cancer is an inhabitant of freshwater reservoirs and rivers with clean water. He cannot live in a dirty pond. It settles on a rocky bottom and in places with a steep clay bank. It lives under stones or in burrows, where it hibernates.
