Etymology: Irolita: From Irolita, a princess in love with prince Parcinus. The beauty of the princess was worthly the world´s admiration. Mythology.
Eponymy: Irolita is a beautiful female character in a fairy story written by Marie-Catherine Le Jumel de Barneville, Baroness d’Aulnoy (1650–1705). The reasoning behind this choice of name is not explained by the author. Edgar Ravenswood Waite (1866–1928) was an English-born Australian zoologist and ichthyologist.

Length at first maturity / आकार / वज़न / Age

Maturity: L_m ?, range 46 - ? cm
Max length : 52.0 cm TL पुल्लिंग / अलिंग; (Ref. 6871)

Occur over soft bottoms of the continental shelf (Ref. 7300, 75154). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 5.1-7.6 cm long and 3.2-3.8 cm wide (Ref. 41308). Males reaches maturity at ca. 46 cm TL. Occassionally caught as bycatch and typically discarded (Ref. 114953).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 15 - 18.5, mean 16.6 °C (based on 27 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00288 - 0.01097), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
