Etymology: Chiloscyllium: cheilos (Gr.), lip, referring to membranous and broad lower lip, presumably of C. plagiosum (proposed without a species); skylion, Greek for dogfish or small shark (See ETYFish); hasseltii: In honor of Dutch physician and biologist Johan Coenraad van Hasselt (1797-1823), who explored the colonial Dutch East Indies with his friend Heinrich Kuhl in 1820 (See ETYFish).
Eponymy: Dr Johan Coenraad van Hasselt (1797–1823) was a Dutch physician, zoologist, botanist and mycologist. [...] (Ref. 128868), visit book page.

Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 27.9 - 29.1, mean 28.7 °C (based on 158 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00398 (0.00176 - 0.00901), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.5 ±0.37 se; based on food items.
Resilience (Ref.
