Crocodile skins are used for the manufacture of exclusive leather products, with the most common\u2010sized skin sold having 35\u201345\u2003cm in belly width. One of the breeding objectives for inclusion into a multitrait genetic improvement programme for saltwater crocodiles is the time taken for a juvenile to reach this size or age at slaughter. A multivariate restricted maximum likelihood analysis provided (co)variance components for estimating the first published genetic parameter estimates for these traits. Heritability (\u00b1SE) estimates for the traits hatchling snout\u2010vent length, inventory head length and age at slaughter were 0.60 (0.15), 0.59 (0.12) and 0.40 (0.10) respectively.
