Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: East Africa to the Line and Tuamoto Islands, north to Ryukyu Islands, south to New Caledonia and Tonga; strays to the Hawaiian Islands. Population from the Philippines, Indonesia, New Guinea, Queensland, and Belau differs in coloration (formerly Canthigaster papua); replaced by Canthigaster margaritata in the Red Sea.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 11.5 cm TL male/unsexed; (Ref. 11441)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 8-10; Anal spines: 0; Anal soft rays: 8 - 10. Ocellus at base of dorsal fin; dark lines radiating from eye; caudal fin brown with pale spots, outer rows may form wavy lines (Ref. 4919).

Biology     Glossary (e.g. epibenthic)

Inhabit sheltered rocky reefs (Ref. 48637). Also live in intertidal reef flats, lagoon and seaward reefs. Occur over open barren areas, also among corals and under ledges (Ref. 9710). Benthopelagic (Ref. 58302). Often found in pairs, sometimes in small groups. Feed mainly on filamentous red and green algae and coralline red algae but also on corals, tunicates, mollusks, echinoderms, polychaetes, crustaceans and bryozoans. Common (Ref. 9710). Monogamous (Ref. 52884).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 205). Displays facultative monogamy where males are constrained to mate with a single female due to resource limitation (Ref. 52884).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02512 (0.01276 - 0.04943), b=2.93 (2.75 - 3.11), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.36 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
