The largest egg produced by any living fish is that of the whale shark (Rhincodon typus). The largest on record measured 30.5 x 14 x 8.9 centimetres (12 x 5.5 x 3.5 inches) and contained a live embryo 35 centimetres (13.8 inches) long – though it's now believed that this specimen was aborted. It was found on 29 June 1953 by a shrimp trawler in the Gulf of Mexico, south of Port Isabel, Texas, USA.
