Abstract
The brood pouch of seahorses can be divided into four sequential stages
on the characteristics of the altered tissue layers during gestation: the
normal stage, the embryo-carrying stage, the embryo-release stage and
the repair stage. The brood pouch is composed of a folded inner
pseudostratified columnar epithelium and a smooth outer stratified
cuboidal epithelium. Three tissue layers between the inner and the outer
epithelia are an inner loose connective tissue layer, a middle smooth
muscle layer and an outer dense irregular connective tissue layer. In the
normal stage, the inner loose connective tissue layer is thick and
vascularised with enlarged blood vessels. In the embryo-release stage, the
inner loose connective tissue layer is extensively vascularised with very
large blood vessels and the smooth muscle fibres invade the outer dense
irregular connective tissue layer. Structures altered during gestation
gradually resume their normal condition in the repair stage. Extensive
vascularisation of the brood pouch during gestation suggests an intricate
paternal-embryo relationship implying other significant roles besides
protective function of the pouch.
