Etymology: Myloplus: Greek, mylos, -ou = grey mullet + Greek, plus, ploos = movement of a serpent; zorroi: Named for Mauricio Camargo-Zorro (Instituto Federal de Educação, Ciência e Tecnologia); alludes to the Latin-American fictional character Zorro, because the special features 'masked' this fish as Tometes, concealing its true identity.
Eponymy: Dr Mauricio Camargo-Zorro is a researcher at the Instituto Federal de Educação, Ciência e Tecnologia, São Paulo. [...] (Ref. 128868), visit book page.

Краткое описание
определительные ключи | морфология | морфометрия
This species is distinguished from its congeners by the following characters: absence of the abdominal keel and prepelvic serrae formed by 13-19 low spines (vs. a well-marked abdominal keel and prepelvic serrae of more than 20 high spines). It differs from asterias, levis, torquatus by having fewer branched dorsal-fin rays 20-22 (vs. 23 or more); from arnoldi, ternetzi, torquatus by having a greater number of branched anal-fin rays 32-34 (vs. 31 or fewer); differs significantly from lobatus, schomburgkii, rhomboidalis by having two rows of premaxillary teeth forming a slight arc (vs. 2 rows of premaxillary teeth forming a shape that resembles the uppercase letter 'A'; shorter dorsal-fin base 27.6-30.1% of SL (vs. 31.8% of SL or higher); differs from asterias, levis, ternetzi, torquatus in having a larger interdorsal distance 11.4-12.7% of SL (vs. 10.8% of SL or lower); differs further from M. ternetzi by the presence of a pair of symphyseal teeth (vs. none); from asterias, levis, lobatus, ternetzi by having a smaller vertical diameter of the eye 27.3-35.4% of HL (vs. 35.5% of HL or greater); from arnoldi, torquatus by having a greater number of total vertebrae 40-41 (vs. 37 or less), by having anterior dorsal-fin rays lacking pigmentation (vs. strongly dark pigmented), and the presence of a diffuse dark band at caudal-fin distal border (vs. the presence of a well-defined dark band); from M. asterias by having an elongated fontanel with similarly sized anterior and posterior portions (vs. very short posterior fontanel and rounded anterior fontanel) (Ref. 114773).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02754 (0.01279 - 0.05932), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
