Embryonic development lasted 9-10 days at 18.5-20.0ºC and 10-11 days at 15.0-16.5ºC. Newly hatched larvae measured 3.90 mm, had the mouth and anus opened, pigmented eyes and almost no yolk. They ¢rst settled 25 days after hatching (10.0-10.5mm total length [TL]) and showed juvenile behaviour and body form 36 days after hatching (14.0mmTL). However, they only showed full juvenile pigmentation patterns 15 days later (17.0mmTL) (16.0-16.5ºC). In addition, a preliminary di¡erentiation between the newly hatched larvae of the most common Gobius species of south-western European shores is presented.engjournal article
