Etymology: Phyllopteryx: Greek, phyhllon = leaf + Greek, pteryx = wing, fin (Ref. 45335). More on author: Lacepède.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 50 m (Ref. 9563). Temperate
Eastern Indian Ocean: southern Australia, from southern Western Australia to New South Wales and Tasmania (Ref. 9563).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 30 - 32 cm
Max length : 46.0 cm TL male/unsexed; (Ref. 9563)
Recorded from the intertidal zone to a depth of 50 m (Ref. 9563). Frequently among seaweeds and coral reefs (Ref. 9137). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
Breeding behaviours and sexual dimorphism were observed in wild-caught weedy seadragons when the photoperiod exceeded 12.5 h daylength and water temperature exceeded 14?C; courtship behaviours typically lasted for 2-4 weeks before the time of breeding (Ref. 85751). Male carries the eggs in a brood pouch (Ref. 205). Gestation periods lasted from 30 to 38 days (Ref. 79764).

Estimates based on models
Preferred temperature (Ref. 115969
): 14.7 - 20.5, mean 17.2 °C (based on 130 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00176 - 0.01137), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.50 se; based on food items.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
