English Name

Marbled puffer

First characterisation

1934 von Longley


Fish size

~ 20 cm







“Sphoeroides dorsalis has a pair of lapets on dorsal surface behind eyes. Snout is long and acute. Nostril is paired, and nares are at ends of short tubes. Interorbital space is narrow and slightly concave. Gill slit is arch shaped and is slightly shorter than pectoral fin base. Gill rakers are very short and number 9 to 12. Mesurements are expressed in percent of SL: head length 32%-40%, snout length 19%-25%, eye diameter 6%-10%, pectoral fin length 13%-17%, uninflated body depth 21%-24%. Pectoral fin has 15 to 17 rays. Dorsal fin is narrow based and has 8 rays. Anal fin is similar in shape to dorsal fin and has 7 rays. Body is covered with small spinules except on dorsum posterior to lappets, on cheeks, and on belly anterior to pectoral fin base. Color is uniformly gray to brown dorsally, with a diffuse bar over interorbital region and one or two diffuse blotches on head behind orbit, and white ventrally, with one to five diffuse spot son lower flank behind pectoral fin base. Lappets on back are dark in adults but may be tan in juveniles. (McEachran 2005, S. 924)

„Diagnostic characters:A blunt-headed fish with heavy jaws forming a beak of 2 teeth in both upper and lower jaws.Dorsal and anal fins set far back near caudal fin. Dorsal-fin rays 8, anal-fin rays 7, pectoral-fin rays usually 16. Prickles are always present on the dorsum to near origin of dorsal fin. A single pair of dark lappets (sometimes difficult to see) on dorsal surface midway between eyes and dorsal-fin origin. Colour: basal pigmentation uniform grey or brown, with a few diffuse spots laterally, posterior to pectoral fins; males exhibit a distinctive but irregular pattern of scrawl-like markings on cheek. Size: May reach 175 mm, common to 125 mm.“ (Shipp 2002, S. 1996)




23 °C - 26 °C




Jungtiere dieser Art sind auch im flacheren Wasser zu finden, ausgewachsene hingegen im tieferen Wasser zwischen 18 und 90 m.

“This species occurs between 18 and 90 m (...) Juveniles apparently occur near shores. (McEachran 2005, S. 924)

„Habitat, biology, and fisheries: Found in moderate depths, 20 to 100 m, and most frequently taken in shrimp trawls. Little is known of its natural history. No directed fishery exists." (Shipp 2002, S. 1996)

Basin size

110 imp.gal.


Diese Art ist möglicherweise giftig.

"Remarks: Although this species has not been reported as toxic, many of its congeners are, and it should not be consumed.“ (Shipp 2002, S. 1996)
