Hemerophis

Hemerophis is a small genus in the family Colubridae, the largest and most diverse snake family on Earth. As currently recognized it holds essentially one species, the Socotran Racer (Hemerophis socotrae), which is endemic to the Socotra Archipelago off the Horn of Africa in the Arabian Sea. Like most racers across the colubrid family, it is a slim, fast, alert, ground-active snake. It was historically grouped with the Old World racers near the genus Coluber and related forms, and modern work has set it apart as its own lineage native to this isolated island system.

Its range is one of the narrowest of any snake genus, restricted to Socotra and its smaller neighboring islands. Socotra is a dry, rugged landscape of limestone plateaus, coastal plains, and arid scrub, and the racer occupies these terrestrial habitats rather than wetlands or dense forest. In general terms, members of racer lineages like this are recognized by a slender build, a long tapering tail, large eyes suited to active daytime hunting, and smooth or weakly keeled scales over a streamlined body. Coloration in island colubrids tends toward muted browns and grays that match rock and dry ground.

The Socotran Racer is a non-venomous, harmless colubrid that poses no medical danger to people. It is not a front-fanged snake and is not aggressive toward humans; like other small racers it relies on speed and concealment to avoid threats. As a typical colubrid racer it feeds on small prey such as lizards and invertebrates, hunts actively by day, and is presumed to reproduce by laying eggs as the great majority of colubrids do. Wild snakes should still be observed and not handled, and any genuine snakebite emergency should be directed to local emergency services or, in the US, Poison Control at 1-800-222-1222.
