Etymology: Chirodactylus: Greek, cheir = hand + Greek, daktylos = finger (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 150 m (Ref. 9492). Subtropical; 23°S - 36°S
Southeast Atlantic: Walvis Bay, Namibia to possibly Natal, South Africa. Natal records are likely to be Chirodactylus jessicalorum.

Maturity: Lm ?  range ? - ? cm
Max length : 180 cm TL male/unsexed; (Ref. 9492); common length : 80.0 cm TL male/unsexed; (Ref. 9492)
The largest species of the family (Ref. 5319). Primarily an offshore species that prefers rocky or muddy banks. Feeds during the day on small, bottom-dwelling invertebrates. Occasionally also on squid and small fish. Also caught by artisanal and game fisheries (Ref. 9492).

Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00638 - 0.04320), b=3.00 (2.77 - 3.23), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
