Content
This is a medium-sized cobra with a rather thin body compared to other cobras. Color varies from gray to brown and black, with white spots or stripes. The white pattern can be so developed that it covers most of the body of the snake. Black and white is widespread in central Thailand, individuals from western Thailand are mostly black, and individuals from other countries are usually brown. The pattern on the hood can be shaped like a spectacle, be shapeless or absent, especially in adults [2] . Adults average 0.9 to 1.2 meters in length [3] and can reach a maximum of 1.6 meters, although very rarely [4] .
This species should not be confused with a monocle cobra ( Naja kaouthia ), living with it in the same range and having a similar size and appearance.
Naja siamensis lives in Southeast Asia, including Thailand, Cambodia, Vietnam and Laos [2] . It is found in a number of landscapes, including lowlands, hills, plains and forests. It is also found in the jungle, and it is sometimes attracted to settlements due to the large populations of rodents in these places [5] .
These are mainly nocturnal snakes [5] . They behave differently depending on the time of day. If a person encounters this snake during the day, it is usually shy and tries to hide in the nearest hole. However, when a person encounters it in the dark, it is more aggressive and more likely to stay in place, having risen and inflated its hood and can spit poison [6] . If the poisonous spit doesn’t work, she may bite. With a bite, she often digs into the victim and, as it were, “chews” it. It feeds mainly on rodents, toads and other snakes [3] [5] .
Naja siamensis is an egg laying snake. The female makes clutches of 13-19 eggs [3] every 100 days. Cubs hatch after 48-70 days depending on the incubation temperature. Offspring become independent from the moment of hatching. The body length of newborns is 12–20 cm and, since they have fully developed poisonous teeth and glands, they should be treated with the same respect as adults [6] .
