Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335); jugumus: From the Latin jugum meaning yoke, in reference to the yoke-like ridge formed by the shoulder rings joined over the nape..

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 20. Trunk rings 12; tail rings 37; subdorsal spines 4/0,1,1,1,1; nose spine moderately large, height about equal to pupil diameter; double spine above eyes moderately long, slightly longer than pupil diameter; lateral head spine double and large; coronet slightly raised; gill openings extending upwards, almost joined at neck ridge; shoulder rings confluent over neck-ridge forming continuous collar (Ref. 42735).
Probably pelagic (Ref. 42735). Maximum length is based on a straight-line length measurement from upper surface (ignoring spines) of first trunk ring, to tip of tail (Ref. 42735). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00177 - 0.01127), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
