  • Remotely operated vehicles (ROVs) wer e used to obser ve and collect the meso pelagic squid Octopoteuthis deletron Young, 1972. I documented numer ous individuals with shortened, blunt-ended arms and regenerating arm-tips, which may be indicative of ar m autotomy, i.e. the jettisoning of a body part as a defense. To test the hypothesis that O. deletron is capable of arm autotomy, laboratory investigations and an in situ experiment using ROVs attempted to induce autotomy. I looked for autotomy… CONTINUE READING
