Lobster Chemosensation

Chemosensory organs of spiny lobsters. A1, first antenna or antennule; A2, second antenna. A1 bifurcates after the basal segments into the lateral and medial flagella, which share many of the same non-aesthetasc sensilla. However, only the lateral flagellum contains rows of aesthetasc sensilla. Figure modified from Schmidt et al. (Schmidt et al., 2006).
