Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 28 - 32; Épines anales: 0; Rayons mous anaux: 3. Greenish brown with close-set dark lines on head and pale lines on body (Ref. 4281).
Occurs in rivers with tidal influence. Found in association with submerged aquatic macrophytes, primarily the eelgrass Zostera capensis (Ref. 26174). Sympatric with Syngnathus acus in the eelgrass beds (Ref. 26174). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
