Yes the antenna on a crayfish are there. But they are there to sensor things when the crayfish are moving. Sort of like a snakes tongue.
Circulatory ?
Antennules are for smell. Antenna are tactile.
it is the antenna, antennule, rostrum, and the maxillipeds (feeding appendages).
The crafish's antennules are the smaller antennas and they aid in balance and provide taste and touch. The larger antennas called the antennae are much more sensative then the antennules, providing the crayfish stronger sense of taste and touch.
The anterior part of a crayfish is called the rostrum because it is a structure that protrudes from the head resembling a beak or snout, much like a rostrum on a ship. It helps the crayfish with sensory perception and sometimes functions in defense or capturing prey.

Crayfish
Crayfish possess two types of antennas: long antennules and shorter antennae, which serve different functions. The long antennules are primarily used for chemoreception, allowing crayfish to detect chemical signals in the water, which aids in finding food and mates. The shorter antennae are more tactile, helping crayfish navigate their environment and sense physical objects or obstacles. This dual antenna system enhances their overall sensory perception, crucial for survival in complex aquatic habitats.
Crayfish are known as both crayfish and yabbies in Australia. "Yabbies" are freshwater crayfish, often found in rivers, creeks and dams in rural areas.
My older crayfish died and my littler crayfish has not yet how do/can they die?
Do crayfish have tarritoris
