Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335); haema: Name from Korean word Haema meaning ‘seahorse’, which connotes ‘representative’ and ‘common’; chosen to indicate that this seahorse is the one most commonly found in Korea..
Environment: milieu / climate zone / depth range / distribution range

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
