Research on Claw Motion Characteristics and Cavitation Bubbles of Snapping Shrimp

Figure 1

(a) Schematic view of the experimental device. The vibration-isolated platform is placed in the center of the aquarium, and the sensors are fixed at a distance of 3 cm in front of the snapper claw. (b) Gray value image of the snapper claw from the side. The inflection points of the claw are marked by circles, and the opening angle is measured to be 82.4°. (c) 3D reconstructed model of snapper claw with a scale of 1 : 1. (d) CT slices of shrimp claw in the x-y direction. The dactyl is inserted into the socket to form a cavity closed on both sides. (e) CT slices of shrimp claw in the x-z direction. The red rectangle indicates the cavity and nozzle structure. (f) CT slices of shrimp claw in the y-z direction. The dactyl is tightly surrounded by socket, representing a fine hermetic seal.
