Etymology: Leptonotus: Greek, leptos = thin + greek, noton = back (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 120 m (Ref. 5316). Subtropical
Southwest Pacific: mainland New Zealand and the Auckland Islands.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 10 - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 5316)
Occurs near piers and wharves to offshore depths of 62-120 m. Specimens have been taken over bryozoan and coarse shell bottom; juveniles in surface plankton tows. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Males may be brooding at 9.95 cm SL.
