Actinopteri (ray-finned fishes) > Tetraodontiformes
(Puffers and filefishes) > Ostraciidae
Etymology: Rhynchostracion: Greek, rhingchos = snout + Greek, ostrakon = a little shell (Ref. 45335).
More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 80 m (Ref. 1602). Tropical; 19°N - 20°S
Western Pacific: Sri Lanka (Ref. 1550) and Sumatra to Fiji, north to the Philippines; Palau and Truk in Micronesia. Matsuura 1999, pers. comm. strongly doubts its distribution in the southern GBR (as reported in Lieske & Meyers 1994, Ref. 9710) and does not know of any reliable record of this species from East Africa.

Estimates based on models
Preferred temperature (Ref. 123201
): 26.7 - 29, mean 28.2 °C (based on 1104 cells).
Phylogenetic diversity index (Ref. 82804
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03548 (0.01708 - 0.07371), b=2.81 (2.62 - 3.00), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Fec assumed to be > 10,000).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (20 of 100).
