Distribution |
Tropical Indo-west-central Pacific, Red Sea, Indonesia, Great Barrier Reef, to Micronesia, Tonga and Samoa; inhabits inshore reefs among rubble to 35 m, although more common on shallow reefs to 4 m. |
|
Features |
Meristics: D 23-27; P 16-18;Trunk rings 14-15; Tail rings 29-32. Head and body: Head length 5.3-6.8 in SL, snout length 1.6-1.9 in HL. Superior trunk and tail ridges discontinuous; lateral trunk ridge straight, ends near anal ring; median dorsal snout ridge entire; principle body ridges not strongly elevated; usually with minute dermal flaps on eye; distal third or more of tail with posterior angles of rings produced to points. |
|
Size |
Reaches about 100 mm TL. |
|
Colour |
Pale red to tan with a dark lateral stripe on the snout and brown dorsally on head; lower half of side and ventral surface of trunk usually with dark brown bars. |
|
Feeding |
Unknown, but likely to feed on small crustaceans. |
|
Biology |
Reproduction: Ovoviviparous (gives birth to live young). The eggs are brooded by the males in a pouch on the underside of the body. The pouch protects the dorsal surface and side of the egg mass, leaving the ventral surface exposed. Males may begin brooding at 62 mm TL. Eggs: Eggs are deposited in 2-17 transverse rows within a gelatinous matrix. Larvae: Planktonic larvae, morphologically similar to adults. Planktonic juveniles (24-29 mm SL) have been taken in the upper 85 m over depths of 1565-2010 m. |

Conservation |
Australian Government Legislation: Marine listed under the Environment Protection and Biodiversity Conservation Act 1999. State Government Legislation: Listed as protected under the New South Wales Fisheries Management Act. |

Etymology |
Cosmocampus is from the Greek, kosmos meaning order or organisation, and the Greek, kampe for sa animal. The specific name maxweberi is for the Dutch explorer Max Wilhelm Carl Weber, who initially descibed the species as Syngnathus punctatus. |
