Statolith validation and age and growth analysis was undertaken for the loliginid squid Loligo plei in the north-west Gulf of Mexico off Galveston, Texas. Statolith increments were shown to be laid down daily based on tetracycline staining of 19 individuals maintained in captivity. Ageing of field-captured individuals from late summer revealed that this species has rapid growth rates and a life span of about five months at least during the warm period of the year in this region of the Gulf of Mexico.
