Magliophis

Magliophis is a small genus in the family Colubridae, the largest and most diverse snake family on Earth. The genus holds just two recognized species of small, slender, ground-dwelling snakes native to the Caribbean, including populations in the Puerto Rico region. They belong to the broad assemblage of New World colubrids and were split out from the wider grouping once called Dromicus, reflecting how Caribbean island snakes have been repeatedly reshuffled as herpetologists refine their relationships. The plain-language name people search for these and similar small terrestrial colubrids is ground snakes.

As with most West Indian ground snakes, members of Magliophis are small and easy to overlook. They live close to the ground in leaf litter, under rocks and logs, and in the soil and debris of forests, gardens, and scrub. They are active foragers that hunt small prey such as lizards, frogs, and invertebrates, which is typical for ground-dwelling colubrids of this size. Like the vast majority of colubrids, they reproduce by laying eggs. Recognition in the field is best done by region and size rather than by any single bold marking: expect a small, smooth-scaled snake with a slim body, found at or near ground level on a Caribbean island.

These are not dangerous snakes to people. They are non-venomous in the medical sense, with no front fangs and no venom delivery system that poses a threat to humans, and they are far too small to be a hazard. Many small colubrids use mild rear-set teeth and weak saliva to subdue tiny prey, but this has no meaningful effect on a person. As a rule, leave any wild snake alone rather than handling it, both for the animal's sake and to avoid stress or a defensive bite. If a snakebite ever causes concern about a person's health, do not wait: contact US Poison Control at 1-800-222-1222 or local emergency services.
