Thyrsites atun Larvae showing increase in size of area occupied by viscera. between 4,08 and 14,25 mm. After this size is reached, increase in head length appears to decrease and reach 0,225 mm/mm increase in length. The snout is 37% of the head length. Initially the snout is only 0,09 mm longer than the eye diameter, but this difference increases with age until at 21,0 mm the snout length is 1,05 mm greater than the eye diameter (Table 4).
