Coelognathus helena
A colubrid in pale brown with dark brown crossbands, the bands on the flanks enclosing white spots that grow fainter towards the rear of the body. A vertical black streak below the eye and an oblique one behind it are diagnostic.
The trinket snake (Coelognathus helena) is a colubrid of South Asia, 90-130 cm long and reaching 1.4 m, of which about 25 cm is tail. Juveniles are pale brown with black crossbands, each enclosing four to six white ocelli. Adults are a darker brown, the crossbands becoming a transverse series of squarish black spots or fading to mere traces of the juvenile pattern. A vertical black streak runs below the eye and an oblique one behind it. Some animals have a white, black-edged collar and others two black stripes on the head. The underside is yellowish. There are 23-27 rows of dorsal scales at midbody, 220-265 ventrals and 75-94 subcaudals. It occurs in forest from sea level to 2,500 m and is also found around houses. Partly arboreal, it adopts a distinctive threat posture, raising the head and compressing and kinking the neck laterally. Besides mice, rats and squirrels it preys on small snakes, geckos and frogs.

Carnivorous: small mammals such as mice, rats and squirrels, small snakes, geckos, frogs and birds
It occurs from sea level to 2,500 m, so preferred temperatures vary with provenance. Provide a clear warm-to-cool gradient and avoid high temperatures for animals from high-altitude localities.
A partly arboreal snake of around a metre, it needs enough floor area to lie coiled with room to spare plus branches or shelves to climb. Place hides on both the warm and cool sides and keep a water container available. It is adaptable enough to live around houses, so secure the lid firmly against escapes.
It feeds mainly on small mammals such as mice, rats and squirrels but also takes small snakes, geckos, frogs and birds. In captivity offer frozen-thawed mice sized to the snake. Hatchlings sometimes prefer reptile prey such as geckos, and may need coaxing onto rodents.
In threat it raises its head and compresses and kinks its neck laterally, and it may strike readily. It is non-venomous, but avoid forced handling while it settles in and give it plenty of cover. Because it eats snakes, keep it singly.
Not listed on any CITES appendix. It is assessed as Least Concern (LC) on the IUCN Red List. It appears neither on the schedule of designated dangerous animals under the Order for Enforcement of the Act on Welfare and Management of Animals nor on Japan's list of invasive alien species. The old name Elaphe helena is still in circulation, so confirm the identity when buying, and check the subspecies, since the three recognised forms differ in pattern and range.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Trinket Snake is 10-15 years. With proper care and nutrition, they can live a long and healthy life.
Trinket Snake typically reaches 90-130cm total length, with a maximum of 1.4m including a tail of about 25cm as an adult. Size may vary depending on care conditions and individual genetics.
