(Perch-likes) > Chaetodontidae
Etymology: Chaetodon: Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Günther.
Environment / Climate / Range
Marine; reef-associated; depth range 0 - 50 m (Ref. 86997), usually 0 - 15 m (Ref. 5288). Tropical, preferred ?
Southeast Atlantic: Known only from the Ascension and St. Helena Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 2272)
Common in shallow waters. Usually observed in pairs or large groups. Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205). Called a cunning fish since it can nibble the bait from a hook without taking the hook into its mouth. The juvenile Thalassoma sanctaehelenae has been observed cleaning the cunningfish of its parasites (Ref. 5288).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01128 - 0.04653), b=3.01 (2.84 - 3.18), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
