To catch this mantis shrimp, Raieta placed the fish, the one hanging
on the string in his left hand, over the mantis shrimp hole, and when
the mantis shrimp struck and pulled the bait deep into its cave he
followed the string down into the cave, with his right hand (to get this
one he had his right arm, up to his shoulder, in the cave), until he could
feel the mantis shrimp claws gripping the fish. He then grabbed both
claws, held them together (tightly), and gently eased the mantis shrimp,
and the bait, up and out of its hole.
