Caption: An adult Coenobita clypeatus hermit crab uses a discarded snail shell for protection: both pairs of antennae are clearly visible. Olfactory receptors are located on the inner pair of antennae, which are bent upwards. The crabs' sense of smell is still underdeveloped in comparison to insect olfaction.
