species of fish
Corythoichthys amplexus, known commonly as the brown-banded pipefish, is a species of marine fish in the family Syngnathidae.
Description
Anatomy
The brown-banded pipefish is a small size fish and can reach a maximum size of 10 centimetres (3.9 in) length. The skin has a base colour of light tan with broad reddish-brown bands on the body, each 3–4 rings wide, which lie across the side and dorsal surfaces, occasionally these are divided to form two closely set bands, and sometimes they are indistinct on the posterior third of the tail. The head lacks prominent stripes behind eye and the ventral surface of anterior trunk rings is blotched with dark brown in males, while often being marked with small paired spots in females.
Reproduction
The adult males and females form monogamous pairs, they are an ovoviviparous species, in which the males brood the fertilised eggs in a brood pouch situated under his tail. The brood pouch protects the dorsal surface and side of the egg mass, leaving the ventral surface exposed. Males are capable of once they attain a total length of 57 millimetres (2.2 in).
The eggs mass consists of 2–17 transverse rows within a gelatinous matrix.
Distribution and habitat
The brown-banded pipefish is widespread throughout the tropical waters of the Indo-West Pacific region, from the eastern coast of Africa to the western Pacific north to the Ryukyu Islands to south the Great Barrier Reef. Records from South Africa and Madagascar require verification.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Corythoichthys amplexus”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q2252527. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
