The three images on this page were sent to Jeff Leis by Sergei Bogorodsky in February 2007. They show three different fish photographed in shallow water in southern Egypt.
The fish resembles the Blackblotched Porcupinefish, Diodon liturosus, but has small dark spots on the dorsal, pectoral, anal and caudal fins. The fins of the Blackblotched Porcupinefish lack spots. The three fish in the images have different shaped blotches, and the fish in the lowermost photograph has very limited spotting restricted to the fin bases.
The fish may be rare colour variants, or possibly hybrids between the Blackblotched Porcupinefish and the Black-spotted Porcupinefish, Diodon hystrix. Alternatively they may be a new species.
To learn more about this fish, specimens are required for examination.
The fish were photographed in shallow water at Marsa Alam, in southern Egypt, about 300 km south of Hurghada. The species seems rather rare in the Red Sea and may not extend to the northernmost portion of Red Sea near Elat.
