The 🇼🇸 Samoan pipefish, scientifically known as Halicampus mataafae, is a marine species within the Syngnathidae family. This species is prevalent throughout the Indo-Pacific region, extending from the 🌊 Red Sea to locales such as Sodwana Bay, 🇹🇼 Taiwan, the 🇲🇭 Marshall Islands, and 🇼🇸 Samoa. It typically resides in tidepools and coral and rocky reefs, inhabiting depths of up to 15 meters (49 feet).

Characterized by solitary behavior and cryptic habits, the 🇼🇸 Samoan pipefish is infrequently observed in its natural habitat. Its diet presumably consists of small crustaceans, and it can attain lengths of up to 14 centimeters (5.5 inches).

The species exhibits ovoviviparity, where males possess brood pouches to carry fertilized eggs; these pouches have folds that do not reach the center, ultimately resulting in the live birth of the young.

The specific epithet of Halicampus mataafae is a tribute to Mataafa, a former king of 🇼🇸 Samoa. It is recognized as a protected marine species under the 🇦🇺 Australian Environment Protection and Biodiversity Conservation Act of 1999.

Halicampus mataafae can be distinguished by its reddish-brown coloration and the presence of small pale spots along its trunk and tail.

Halicampus mataafae is likely to be threatened by ongoing declines in coral reefs across the Indo-Pacific (Bruno and Selig 2007). The corals are threatened due to antropogenic pollution, overfishing, and the effects of climate change and ocean acidification (Carpenter et al. 2008). It's not clear how this is affecting the species, as little is known about their dependence on corals or the effect of coral loss on population size. The species is also able to use rocky reef habitats.

The species may also be caught as bycatch and/or be targeted for use in traditional medicine and the aquarium trade (Vincent et al. 2011). Further research is needed to determine the levels of offtake and trade for this species.

Threat classification from the IUCN Red List.
