Description:
The embryonie development of Loligo forbesi was observed from 14-day-old eggs to natural
hatching. Egg strands were spawned in floating cages by wild-caught females in the Azores Islands, air-shipped to Galveston, and incubated in a closed seawater system. The period from spawning to hatching ranged from 68 to 75 days at a mean temperature of 12.5°C (SD 0.5°C). The diameters of individual eggs ranged from 3.0 to 3.1 mm and the dorsal mantle lengths of hatchlings ranged from 4.3
to 4. 9 mm. T he major developmental patterns were nearly identical to those of L. vulgaris (eastern Atlantic Ocean) and L. pealei (western Atlantic Ocean), except that L. forbesi took Ionger to hatch because of the larger embryos and hatchlings. The most noticeable differences in development involved
the nurober and distribution of Chromatophores. The Chromatophore pattern was one of the best criteria for staging L. forbesi in late development
