In situ observations on a large squid-spawning bed in the eastern Gulf of Mexico.
Malacologia, vol. 29(1): 135-141.

ABSTRACT: A loliginid (probably Loligo plei) spawning bed was traversed by a remote-controlled submersible during a survey off Charlotte Harbor, Florida, in June, 1985. This large area of sand bottom was covered with small clusters of egg capsules. Such a pattern may indicate that large groups of squids concentrate in spawning aggregations over patches of suitable substrate. Preserved hatchlings from retrieved egg capsules bring into question the use of chromatophore patterns for specific identification of preserved specimens of early juvenile Loligo spp. that are sympatric and similar morphologically.

Loliginid eggs Squid egg capsules covering 50-80% of a sand bottom. Egg capsules were arranged in groups of about 10-40 with their bases collocated. Estimated NE-SW extent of spawning bed was around 40 meters.
