Summary:
A dark orange to brownish toby covered in pale spots with a yellowish belly, a black blotch on the dorsal-fin base usually edged in blue dorsally (may be ocellated in juveniles), head usually with about 8 to 10 dark lines radiating from the eye, cross-bands usually on interorbital and upper portion of the snout, and a brownish caudal fin with pale spots that may form wavy vertical lines on the outer part of the fin. This species usually lacks longitudinal blue lines between the eye and the dorsal-fin origin.
This species is easily confused with the Netted Toby, Canthigaster papua.

Solander's Toby, Canthigaster solandri (Richardson 1845)

More Info


Distribution

Northern Great Barrier Reef to about Sydney, New South Wales. Elsewhere the species occurs in Western-central Pacific.
Occurs on inshore and offshore reefs habitats, including reef flats, lagoons, seaward reefs and seagrass beds.

Features

Dorsal fin 8-10; Anal fin 8-10. 

Colour

Head ground colour bright golden yellow or purplish, that of back and sides purplish brown; radiating lines about eye and on body light blue; chin and throat bright golden yellow, sometimes a faint yellowish  tinge extending posteriorly on belly; distal half to two-thirds of caudal  fin bright golden yellow, fin spotted, usually with dark-bordered light spots arranged in vertical rows, spots sometimes vertically elongated forming 5 to 7 broken vertical bars, especially distally on caudal fin; base of dorsal with a blue line transversely across rays, then a dark area/spot at base of dorsal fin sometimes ocellated, sometimes scarcely evident; if ocellated, the light line is rarely entire, being broken into curved oblong spots; then a broader blue transverse line proximally to point of articulation; a very thin light blue line transversely across base of pectoral-fin rays just distal to point of articulation of the rays; distal portions of dorsal, anal, and pectoral fins pale, sometimes dorsal with faint yellowish tinge.

Feeding

Feeds mostly on filamentous red and green algae and coralline red algae, along with coral polyps, sponges, tunicates, molluscs, echinoderms, polychaete worms, crustaceans and bryozoans.

Biology

Males are larger than females and defend territories that include multiple females. Spawning occurs during the day, with females depositing their eggs into an algal nest.

Remarks

Canthigaster petersii Allen & Erdmann 2012, replaces C. solandri in the Indian Ocean. 

Similar Species

The similar Canthigaster papua differs from C. solandri in having a more orange snout than the rest of the body, stripes along the back (vs. no stripes on C. solandri), usually a complete ocellus at the base of the dorsal fin in adults (vs. incomplete or indistinct ocellus in C. solandri - juveniles may have an ocellus), spots on the caudal fin (vs. an orange caudal fin with the spots on the distal half to two-thirds of the fin forming vertical blue stripes - less obvious in juveniles). C. papua has a dark abdomen, whereas C. solandri also has a more yellowish abdomen.

Etymology

The species is named in honour of Swedish naturalist Daniel Solander who accompanied Captain Cook, and discovered this species during Cook’s first voyage. Solander subsequently described the species in an unpublished manuscript.
