Halophila capricorni is a poorly known seagrass species and records are patchy and rare. The species lives in deeper waters and may be more widely distributed than currently reported. The overall population trend is unknown. More research is needed on taxonomy, distribution, general biology and threats. This is a fast recolonizing species and it lives in deeper waters. Halophila capricorni is listed as Least Concern.
|Range Description:||Halophila capricorni is found in the Pacific Ocean on the Great Barrier Reef, Australia, north through the Torres Straits, and across the Coral Sea to New Caledonia.|
Native:Australia; New Caledonia

|Population:||Records for Halophila capricorni are patchy and rare. Overall population trends are unknown.|
This species has been collected commonly in the Great Barrier Reef in recent surveys in deeper water (Coles et al. 2000).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Halophila capricorni lives in deeper waters from 21-54 m in sandy and muddy substrates. It readily sets seed. Halophila capricorni has leaves that are similar to H. decipiens, except that hairs are only on one side of the leaf. Flowering also differs; in H. capricorni it is truly monoecious (male and female flowers on separate nodes on the same plant).|
|Major Threat(s):||Major threats to Halophila capricorni are unknown. Localized threats may be caused by increased sediment loads in water. Trawling activities may also create localized threats.|
There are no specific conservation measures for Halophila capricorni. It may be present in some parts of the Great Barrier Reef Marine Park. More research is needed on taxonomy, distribution, general biology and threats of this species.
