Abstract and Keywords
This chapter will consider the control of posture and walking in decapod crustaceans (crabs, lobsters, rock lobsters, and crayfish). The walking system of crustaceans is composed of five pairs of appendages, each with seven articulated segments. While crabs sideways walking relies on stereotyped trailing and leading leg movements, forward/backward walking in lobsters and crayfish is achieved by different movements in the different legs, depending on their orientation versus body axis. Largely independent neural networks, localized in each of the 10 hemi-segmental thoracic ganglia, control each leg during locomotion. Each of these networks is modularly organized, with a specific central pattern generator (CPG) controlling each joint. Although coordinating interneurons have been described, inter-joint and inter-leg coordination is largely maintained by sensory feedback. Recently, the key role of proprioceptive signals in motor command processing has been addressed thanks to hybrid system experiments and modelling.
Keywords: walking, decapods, crustaceans, locomotion, movement, legs, crabs, lobsters, crayfish
