How does the difference in the function of each relate to the location of the suckers on each?
The location of the suckers plays a factor in the tentacles because when a squid captures a prey, it uses its suckers at the tip of the long retractable tentacles to the creature. The location of the suckers also plays a factor in the arms because when a squid contains its prey within its eight arms, the suckers would not allow the prey to escape.
