Best Answer

Blue crabs have antennas because this is where some of its chemoreceptors are located. A blue crab uses these organs to sense its prey. The prey releases chemicals that these organs can use to locate the prey. These organs mainly serve as two of five of a blue crab's senses which are taste and smell.
