The term 'Lobster Feature' refers to the physical characteristics of a lobster. These features include a PINCER, which is a two-part CLAW used for grasping and defense; an ANTENNA, which is a sensory organ used for detecting movement and vibrations; and a CLAW, which is a large, curved appendage used for crushing and cutting food. All of these features are essential for a lobster's survival in its natural environment.
