Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335); paradoxus: Name from Latin 'paradoxus' meaning strange and contrary to expectation; referring to the unusual morphology relative to all other seahorses.

The holotype was collected from mid-continental shelf benthos (102 m); at this depth, high energy waves sweep the bed of the Great Australian Bight, producing expanses of rippled sand interspersed with sponge and bryozoans stabilised 'islands'. The site has a complex, highly diversed assemblage of bryozoans, including Adeona, a number of bushy flexible species (Family Catenicellidae), 'lace corals' (Fam. Phidoloporidae) and some sponges, on coarse substrate of calcareous sand. The female holotype collected in late July had a greatly distended abdomen holding eleven hydrated oocytes approximately 2 mm in diameter (Ref. 85152).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±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).
