Etymology: Phycodurus: Greek, phykon = seaweed + Greek, dora = skin (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 4 - 30 m (Ref. 9002). Temperate; 32°S - 39°S, 115°E - 140°E (Ref. 57011)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 9002)
Eastern Indian Ocean: endemic to southern Australia.
Usually occur over sand patches close to reefs with kelp, feeding on mysids and other crustaceans. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). One of the most spectacular examples of camouflage: neither prey nor predators recognize it as a fish.
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
About 250 eggs are incubated by males on the underside of the tail, where they are embedded in spongy tissue (Ref. 31838).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.45 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
