The "Macrotritopus" juvenile stage of O. defilippi. This life stage is noted for its extraordinarily long 3rd pair of arms. This animal has a mantle length of 1cm. The species of these long armed pelagic juveniles was determined by bringing healthy specimens to the NRCC in Galveston and growing them to adult size (See Hanlon R.T., Forsythe J.W. and S. von Boletzky, 1985).
