Etymology: Iniistius: Latin, in = in + Greek, istion = sail. More on author: Rüppell.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 21 m (Ref. 122743). Tropical; 27°N - 10°S, 42°E - 151°E
Indo-West Pacific: Red Sea, Persian Gulf, and the coasts of India (Ref. 5374); and eastern Papua New Guinea (Ref. 11441).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 28.5 cm TL male/unsexed; (Ref. 30573)
Probably inhabits open sandy bottoms and dives head-first into the sand with the approach of danger (Ref. 5374). Dives into sand to sleep safely at night or to hide when alarmed (Ref. 90102).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.4 - 29.1, mean 28.1 °C (based on 706 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00402 - 0.02726), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100) .
