Scientific Details

Meristics.
Dorsal fin spines/rays: 13-14
Anal fin spines/rays: 3-4
Caudal fin rays: 10
Pectoral fin rays: 5-6
Body rings: 12-14 + 51-60
Subdorsal rings: 1.25-0.50 + 1.25-1.75 = 2.25-2.50

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Detailed descriptions of fin count and other meristics are in:
Gomon. M.F., Bray, D.J. & Kuiter, R.H. (eds) (2008) Fishes of Australia's Southern Coast. Sydney : Reed New Holland 928 pp.

Order level detail.
Mostly long, slender fishes with a small mouth at the end of a long tubular snout, although some species are deep-bodied. All are partially or completely encased in bony rings or dermal plates. Most are cryptically-coloured and often have dermal appendages providing further camouflage.

Family level detail.
A large and diverse group of pipefishes, seahorses, seadragons and pipehorses. All have semi-flexible bodies encased in bony rings and a tiny mouth at the end of a tubular snout. They lack fin spines and pelvic fins, and other the fins may be reduced or absent. Syngnathids have a unique reproductive mode. The sexes are separate and females deposit their eggs into special abdominal brood pouches or onto modified exposed regions under the trunk or tail of their male partner. The males incubate and nourish the developing embryos until they hatch. These extraordinary cryptic fishes are extremely well-camouflaged and often ornamentation such as filaments and other appendages on their bodies to closely resemble their surroundings.
