There is no difference between an antennule and antennae. An antennule is just a small antennae. Antennules are basically the same, but just in size that they vary. They both have the same purposes, the antennae is the plural form of saying the bigger antenna.
The antennules and antennae
Some animals that live in freshwater and have antennae include freshwater shrimp, freshwater crayfish, and water beetles. These antennae help them sense their surroundings, locate food, and communicate with other members of their species.
they are all part of the cephlathorax
They are related because they all perform some part in the crayfish. Without those parts the crayfish will not survive.They are not related at all!!
Crayfish excrete waste primarily through specialized organs called green glands, located near the base of their antennae. These glands filter waste products from the blood and help regulate water balance. The waste is excreted as a dilute urine-like solution, which is expelled through openings near the base of the antennae. This process is vital for maintaining the crayfish's internal environment and overall health.
Crayfish have the ability to regenerate practically any appendage that gets broken off. They can regrow legs, claws,antennae, even eyes if they happen to get snipped off in a fight.
A crayfish can have as many eggs as it wants it just has to be healthy but I think it can lay 50-200.
