New research has unveiled a captivating electric blue tarantula species in Thailand. A team of Thai researchers encountered this spider during their expedition to Phang-Nga province in the southern region. Here they were studying the variety and geographic range of tarantulas in Thailand.

Narin Chomphuphuang, a researcher from the Department of Entomology and Plant Pathology at Khon Kaen University, has described a previously unknown tarantula species that showcases a mesmerizing blue-violet hue, reminiscent of dazzling electric blue spark, living in a mangrove forest.

In a bid to highlight their discovery and support the indigenous Lahu people of northern Thailand, a community to which Sippawat belongs, the team conducted an auction to grant the privilege of naming the new species. The name Chilobrachys natanicharum emerged from the names of two executives from the company that won the naming campaign.

The most captivating thing about this animal is the presence of blue coloration in animals due to its rarity in nature. The scarcity of blue in nature can be attributed to the challenges associated with absorbing and reflecting specific light wavelengths.

How The Blue Came About

The researchers clarified that this distinct coloration results from the configuration of “biological photonic nanostructures,” rather than conventional pigments. In essence, the vibrant electric blue hue doesn’t stem from the presence of blue pigments. It rather originates from the exceptional structure of their hair. Which integrates nanostructures capable of manipulating light to produce this striking blue appearance.

Distinctive Look

The tarantula’s distinctive coloring results from the presence of two distinct types of hairs. Metallic-blue and violet, distributed across various parts of their body. This includes the legs, chelicera (pincer-like mouthparts), and carapace (upper shell).

The spiders’ coloring and other characteristics exhibited variations depending on their sex and age. Female and young male tarantulas tend to display a greater abundance of violet-colored hairs on specific body parts, relative to the metallic blue ones.

Preferred Habitat

The newly discovered tarantula inhabits tree hollows, making it challenging to capture. Researchers had to scale trees to entice the spiders out. Tarantulas are categorized as either terrestrial or arboreal. However, the Chilobrachys natanicharum, as noted by the researchers, displays remarkable adaptability by thriving in both environments.

How Rare Is It?

Nonetheless, due to the decline of mangrove forests, largely attributed to deforestation, the electric blue tarantula has become one of the world’s most scarce tarantula species, according to Chomphuphuang.
