Scientists have recently unearthed a new tarantula species called Chilobrachys natanicharum in the Thai forests. This remarkable arachnid sports an electric blue-violet hue, mimicking the appearance of electrical sparks. Interestingly, this striking color is not due to blue pigmentation but results from the unique nanostructures in its hair that manipulate light. These nanostructured hairs are distributed across its legs, pincer-like mouth appendages (chelicera), and upper shell (carapace). Chilobrachys natanicharum is a versatile species, inhabiting both the ground and trees within tree hollows. Tarantulas, in general, are large, hairy spiders from the Theraphosidae family, with over 900 species worldwide, excluding Antarctica. They are nocturnal predators with an average length of five inches and a leg span of up to 11 inches.
Facts/Terms for UPSC Prelims
- Theraphosidae: Theraphosidae is the scientific family classification for tarantulas. These spiders are known for their large size and distinctive features, including hairy bodies and slow movements.
- Nanostructures: Nanostructures are extremely small materials or patterns with dimensions on the nanoscale, often less than 100 nanometers. In this context, nanostructures in the tarantula’s hair manipulate light to produce its unique blue appearance.
- Carapace: The carapace is the hard, protective upper shell or plate covering the front part of the tarantula’s body. It provides structural support and protection for vital organs.
- Arboreal: The term “arboreal” refers to animals that live primarily in trees. In the case of Chilobrachys natanicharum, it means that this tarantula species inhabits tree hollows in addition to terrestrial environments.
- Nocturnal Predators: Nocturnal predators are animals that are active and hunt during the night. Tarantulas, including Chilobrachys natanicharum, are skilled nocturnal hunters that use their keen senses to locate prey in the dark.
