More Info


Distribution

Known from the tropical Indo-west-central Pacific, including the Maldives, Indonesia, Papua New Guinea, Micronesia (Marshall Islands), Fiji and Rowley Shoals off northwest Australia. The Halimeda Ghostpipefish is usually seen near Halimeda algal beds in sheltered inshore areas and coral reefs to 23 m.

Features

Dorsal fin V + 16-18; anal fin 17-19; pectoral fin 22-25; pelvic fin I, 6; caudal fin 16; vertebrae 32.

Head and body elongate, laterally compressed, encased in a series of bony plates; snout, long, tubular snout; olfactory rosette sexually dimorphic, females with small dorsal patch of 3-5 lamellae, males with larger patch with 15 lamellae; caudal peduncle short; abdominal spinules few to numerous; cutaneous papillae always present at midpoint of snout.

Two widely separate dorsal fins, the first spinous and elongate, second rounded and composed of unbranched rays; pelvic fins expanded and elongate, united to form a brood pouch in females; caudal fin short, truncate or slightly rounded; fin membranes entire.

Size

To 7 cm; females are larger than males.

Colour

Usually greyish or green in colour, usually resembling the coralline alga Halimeda, often with darker speckling and white mottling; dermal papillae red; dark blotches often present on each interspinal membrane between 1st and 3rd dorsal fin spines. Halimeda Ghostpipefish are able to change colour to match their surroundings.

Feeding

Feed on tiny crustaceans, especially mysids, which are rapidly sucked in through the long tubular snout. Ghostpipefish are ambush predators, and stealthily appraoch their prey in a head-down position.

Biology

Females brood their eggs in a special pouch (marsupium) formed from the united pelvic fins. The well-developed larvae hatch at approximately 3 mm with pigmented eyes, a fully formed mouth and advanced body spination.

Fisheries

Although of interest to aquarists, ghost pipefish are very difficult to maintain in captivity.

Conservation

Marine Listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) http://www.environment.gov.au/coasts/species/marine-species-list.html

Similar Species

Solenostomus halimeda is most similar to S. cyanopterus, differing in having a more slender snout, abdominal prickles, and in lacking a premaxillary spine in males.

Etymology

Solenostomus is from the Greek soleno, meaning tubelike, and stoma, meaning mouth. The species is named halimeda due to its close resemblance to the marine alga Halimeda.
