(See ETYFish); microdon: micro-, from mikros (Gr.), small; odon (Gr.), tooth, referring to numerous small teeth (>200 rows in each jaw). (See ETYFish).

توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0. Lower lobe of caudal fin hardly developed, its upper edge not rippled and a subterminal notch present (Ref. 13565). Uniformly dark brownish-grey, darker on posterior edges of pelvic, dorsal, anal and caudal fins (Ref. 13565).

Found on the continental and insular slopes, occasionally wandering onto continental shelves (Ref. 13565). Inactive and sluggish (Ref. 13565). Probably eats bony fishes, elasmobranchs and invertebrates (Ref. 244). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother, uterine milk is consumed additionally (Ref. 50449). Pups number 2 to 4 in a litter (Ref. 244), size at birth between 70 (Ref. 244) and 140 cm TL (Ref. 13565). Caught very rarely by deepwater demersal longline fisheries in some areas. Utilized for its fins (limited value), meat and cartilage (Ref.58048).

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

Exhibit ovoviparity (aplacental viviparity), embryos feed on yolk and ova, also consume uterine milk (Ref. 50449) with 2-4 young in a litter (Ref. 13565; Ref.58048). Size at birth between 70 and 85 cm (Ref. 26346 reports it at about 140 cm TL). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 4.8 - 12.7, mean 8.2 °C (based on 793 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00047 (0.00023 - 0.00095), b=3.29 (3.10 - 3.48), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.5 se; based on diet studies.

جهندگی (Ref. 120179): خیلی آهسته, كمينه زمان لازم براي دو برابر شدن جمعيت بيش از 14 سال (K=0.17; Fec=2).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

طبقه قيمت (Ref. 80766): Unknown.
