Here we report two types of skeletal deformities, ‘pughead’ and ‘short-tail’, observed for the first time in the adult Atlantic goliath grouper (Epinephelus itajara). Photographic documentation of these deformities was made for only three individuals during our studies of their spawning aggregations. ‘Pugheadedness’ was documented in Brazil and Florida, and the ‘short-tail’ deformity was documented only in Brazil. Skeletal deformities are rare, have very low frequencies in wild populations and appear to be initiated during early development. There was no apparent effect of the condition on the adult goliath grouper, as they appeared robust and healthy. |
