ability to collect food particles due to a larger capturing surface and a greater distance. The sea cucumbers picked up food particles from the sediment using the adhesive force and mechanical entrapment ability of the tentacles [8]. Sweeping and raking are the two main modes of tentacle locomotion in sea cucumbers [25]. These modes are found across a range of dendrochirota and aspidochirotid species. Video observations of the A. japonicus feeding strategy indicated that all sizes of sea cucumbers placed their tentacles on food sediments, extended them like “fingers”, and then used them to “grasp” the food particles and delivered them to the mouth.
