Magnoteuthis microlucens: Arrangement of arm suckers

Richard E. Young and Michael Vecchione

Arm suckers tend to be largest in mid-arm and the relative size of the largest arm II suckers can be much greater than comparable suckers on arms IV. One might expect that such features would provide excellent species-specific characters. However, the arrangement of suckers and their relative sizes is highly variable. The suckers of arms II and IV of four different specimens of Mg. microlucens are shown below. For each specimen the suckers maintain their relative sizes but not between specimens. Sucker are numbered, in white, from the base of the arm.
