Chilobrachys natanicharum, previously known in the trade as Chilobrachys sp. Electric Blue, is a tarantula from Thailand, scientifically described only in 2023. It is the only tarantula living in Thai mangrove forests, where, in addition to burrows, it inhabits tree hollows. Its body is brown, but its legs shimmer blue-violet; this color is due to the structure of the hairs, not pigment. An adult female has a leg span of 12–17 cm. It digs long tunnels and spins a lot of webs. It lacks stinging hairs, has a potent venom, and its bite is comparable to a hornet’s sting. It is fast and quick to defend itself. For experienced keepers. Requires a thick layer of moist substrate.
