of fish vary through the sex. The top third of the females belly is deep (when egg bound), twice the breadth of the lower two thirds below the vent. The male is the "tailing" with the twin folds below the vent. The folds of the skin make the middle third and during the "brooding" of the young they swell in size until the young are released from the pouch (at a size of 22 mm to 35 mm).

''Syngnathus temminckii''
The southern African species '' Syngnathus temminckii'' ( Kaup, 1856) was until recently synonymised with ''S. acus''. However, morphological data clearly show that it is distinct, and genetic data indicate that it is not even the sister taxon of ''S. acus'', but of another southern African species, the river pipefish '' S. watermeyeri''.Mwale, M., Kaiser, H., Barker, N.P., Wilson, A.B. & Teske, P.R.
