(Upper) A male golden king crab with part of the carapace cut away to show two Careproctus egg 
masses in different stages of development. (Lower) An early uneyed egg mass (right), a late un- 
eyed egg mass (center), and a larvae cluster (left) taken from a single golden king crab. 
(CL>135 mm; Table 3). The probability of a male 
dying in the holding tank of a commercial vessel was 
0.035 if the crab contained snailfish eggs and larvae 
and 0.025 if the branchial chambers were empty, in- 
dicating that snailfish infestion increases the hold- 
ing mortality of crabs. 
Association between crab and snailfish 
embryonic development stages 
Mature female golden king crab carried snailfish 
embryos in all three stages of development (uneyed, 
eyed, and larval) only when they themselves were
