A largely unknown species endemic to the northern and southern coast along the eastern extent of New Guinea. Its range is limited and somewhat fragmented with a high degree of habitat destruction (high pollutant loads and dynamite fishing practices). This species may also be subject to an unknown level of exploitation by the aquarium industry.

Habitat and Ecology [top]

Habitat and Ecology:This species resides in tropical waters on coral reefs typically observed in 3 to 18 m depth. H. strahani reaches a maximum size of 80 cm TL. This species is nocturnal and individuals are commonly found in crevices and under coral heads during the day. Known to prefer areas of abundant high coral. Males mature at approximately 60 cm TL. The biology of this species is almost entirely unknown.

Threats [top]

Major Threat(s): It is unknown if this species is utilized by the aquarium industry. However, this is a very attractive and hardy species that may be sought after for public and private aquaria. This small population is very susceptible to habitat destruction via high pollutant levels and dynamite fishing practices.

Conservation Actions [top]

Conservation Actions: None. Based on the restricted distribution of this species and high risk of habitat destruction this species requires scientific examination to assess its conservation status.
