Yes they do have bristles. They have three main places where they are at.In the Thorax the Abdomen And the Exopodite.
Crayfish have swimmerets on the abdomen.
A crayfish can have as many eggs as it wants it just has to be healthy but I think it can lay 50-200.
Crayfish can hear, but they do not have ears, so they do not hear in the usual sense. Our ears pick up vibrations via the eardrum and tiny bones in our ears, but crayfish have thousands of sensory bristles. Some of these sensory bristles respond to chemicals, others to touch, but either way, they enable te crayfish to not only hear, but also to smell and feel.
Crayfish, which are crustaceans, differ from annelids in several key ways: firstly, crayfish have an exoskeleton made of chitin, while annelids possess a segmented body covered by a moist cuticle. Secondly, crayfish exhibit jointed appendages for movement, whereas annelids have soft, segmented bodies with bristles (setae) for locomotion. Finally, crayfish have a complex nervous system with a brain and specialized sense organs, while annelids have a simpler nervous system with a nerve cord and ganglia.
The main structures of a crayfish under the exoskeleton of the abdomen are the Cephalothorax and the abdomen. The Cephalothorax is made up of the head and thorax and the abdomen has 7 segments.
Bristles were often made out of the bristles of boar before plastic bristles were invented. They might have also made them out of types of plant.
The different types of bristles used in paint brushes are synthetic bristles, natural bristles (such as hog hair or sable), and blended bristles (a mix of synthetic and natural fibers).
Bristles is what they are called
A toothbrush also has bristles.
The Latin word for bristles is setis.
