The Palawan Kukri Snake (Oligodon notospilus), also known as the Palawan Short-headed Snake, is a nonvenomous colubrid that only lives in the Palawan Archipelago in the Philippines. It is a member of the extensive Oligodon genus, which contains over 90 species widespread throughout central and tropical Asia. The snake earns its common name from its distinctive, blade-like rear teeth that mirror the curved shape of a traditional Nepalese kukri knife.

The Oligodon notospilus is endemic to the Greater Palawan Faunal Region, with confirmed populations found on the Palawan mainland and islands of Busuanga, Balabac, and Calauit. While historical records once suggested the species lived in Mindanao, subsequent research has clarified that these accounts were erroneous. It was also previously treated as a subspecies of Nostopilus vertebralis, but modern herpetological research regards it as a separate species again and has solidified its status as a distinct species unique to the Palawan group of islands.

The Palawan Kukri Snake inhabits Palawan's tropical moist lowland forests, shrublands, and even degraded forest landscapes. It prefers the security of damp microhabitats like thick leaf litter, the undersides of fallen logs, and dense undergrowth near stream banks. While it is mostly found in undisturbed habitats, it is occasionally spotted near human settlements that overlap with its natural territory, although these sightings on the Palawan mainland are now getting rare.

The most fascinating about the Palawan Kukri Snake is its specialized diet of reptile and bird eggs. It can swallow whole eggs that are proportionate to their head and body size, and for eggs that are too large to swallow, its "kukri" teeth act as surgical tools, allowing the snake to slit open the eggs. This allows the snake to insert its head and consume the nutrient-rich yolk efficiently without needing to swallow the whole eggs. Although eggs are its primary food source, the snake is an opportunistic feeder that may also prey on small frogs, lizards, and invertebrates to supplement its nutritional needs.
