The many-banded pipefish is usually seen in pairs, and is almost always found swimming upside down against the ceilings of underwater caves (2). Like other pipefish, it uses rapid waving of its dorsal and pectoral fins to swim (5). The diet of the many-banded pipefish consists of fish larvae and small crustaceans (2), which it sucks into its tubular snout with a pipette-like action (2) (4) (5).
Members of the Syngnathidae family have an unusual breeding strategy in which the male rather than the female becomes pregnant. The female many-banded pipefish lays its eggs into a specialised ‘brood pouch’ beneath the male’s tail, where the eggs are fertilised and are incubated by the male until they hatch (2) (3) (4) (5).
Little other information is available on the breeding behaviour of this species, but like most other syngnathids the many-banded pipefish is likely to have spherical eggs, and the larvae resemble miniature versions of the adults. Many syngnathid species form monogamous pair bonds, and some pairs even perform daily greeting rituals during the breeding season (4).
The many-banded pipefish is likely to be vulnerable to a range of predators, including fish, sharks, turtles and marine mammals (4).
