Which appendages are covered in chemoreceptors vital for detecting odors in the water?
Answer
Small Antennae (Antennules)
Chemical perception is the lobster's primary means of gathering critical information from its environment, often superseding vision in importance on the dark ocean floor. This sensory input is primarily gathered by the Small Antennae, also known as antennules. These structures are densely covered with specialized structures called chemoreceptors, which are delicate hairs capable of detecting chemical signals and odors dissolved in the surrounding water. This ability is crucial for locating distant food sources, identifying the presence of predators, and finding potential mates, functioning as the organism's primary long-range chemical detection system.
