Muscular hydrostats.

Muscular hydrostats like octopus arms and elephant trunks enable complex movement without rigid skeletal support, challenging traditional notions of mobility.

• Why it matters: Understanding how animals move without bones addresses gaps in biomechanics and could inspire innovative designs in robotics and prosthetics.
• What they did: The study examines muscular hydrostats—appendages composed solely of muscle and connective tissue—highlighting their structure and function across various species.
• The result: Findings demonstrate that muscular hydrostats facilitate dexterous and versatile movements, expanding knowledge of biological mobility and potential bio-inspired engineering applications.
