Marine; brackish; benthopelagic; depth range 0 - 160 m (Ref. 26346).   Temperate

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Southwest Pacific: Norfolk Island and New Zealand, including the Kermadec Islands.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 150 cm WD male/unsexed; (Ref. 12951); common length : 100.0 cm TL male/unsexed; (Ref. 9258)

Short description Morphology | Morphometrics

Olive-green, yellow or dark brown dorsally with pale blue or grey markings; white ventrally (Ref. 26346). No caudal fin (Ref. 26346).

Biology     Glossary (e.g. epibenthic)

Occurs in bays, estuaries, and near rocky reefs (Ref. 12951). Usually solitary (Ref. 12951). Feeds on clams, oysters, worms, and crabs (Ref. 12951). Ovoviviparous (Ref. 50449). Although the spine on the tail is capable of inflicting a painful wound, the poison is quickly neutralized by immersion of the injured area in hot water (Ref. 26346).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Young are born at less than 50 cm (Ref. 26346).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00119 - 0.01218), b=3.08 (2.83 - 3.33), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  High vulnerability (59 of 100) .
Price category (Ref. 80766):   Medium.
