A brand new species of tarantula discovered scurrying across the forests of Thailand shimmers with dazzling blue highlights.
Its discoverers have named the beastie Chilobrachys natanicharum, and say it is the primary tarantula ever recognized residing in Thailand’s mangroves. Findings like these spotlight the worth of preserving these pure habitats, the place distinctive species have carved out small however necessary ecological niches.
Actually, the spider had been identified for a while within the unique spider commerce, the place it was known as the Electrical Blue Tarantula. Nonetheless, it had not been formally described, nor did scientists know the place the species made its house.
Following the invention final 12 months of the primary tarantula in Thailand identified to make its house in bamboo stalks, a Thai group led by arachnologist Narin Chomphuphuang of Khon Kaen College launched into an expedition to search out these blue beauties.
“The primary specimen we discovered was on a tree within the mangrove forest,” Chomphuphuang says.
“These tarantulas inhabit hole bushes, and the issue of catching an electric-blue tarantula lies in the necessity to climb a tree and lure it out of a fancy of hollows amid humid and slippery situations. Throughout our expedition, we walked within the night and at evening throughout low tide, managing to gather solely two of them.”
Blue is without doubt one of the rarest colours that seem in nature. Blue flowers are uncommon; blue leaves are nonexistent. That is as a result of blue pigment is extraordinarily uncommon and arduous for crops to make. Most blue flowers are the results of the mixing of different pigments.
Blue will be present in animals, primarily in birds, fish, and bugs resembling butterflies. There are a number of species of tarantula which have blue coloration too. On this case, the vivid blues are usually not the results of pigment; quite, they’re produced by structural coloring. That is when tiny, nanoscopic constructions mirror the sunshine in such a approach that it shimmers blue and violet.
The key of the blue coloration of tarantulas was solely found a number of years in the past, and it is an interesting one. Completely different species of tarantula world wide, from distant branches of the tarantula household tree, all appear to shimmer with the identical vivid shade of electrical blue, even when the nanostructures accountable are totally different.
We nonetheless do not understand how, or why, that is the case, however observing how species in numerous habitats are patterned, and the way they use their blue coloring, could also be helpful in figuring it out.
Chilobrachys natanicharum has vivid blue and violet markings on its legs, pedipalps, and chelicerae that flash and shimmer when the spider raises its legs, a posture tarantulas assume defensively, or throughout courting. Latest analysis has additionally discovered that blue tarantulas can understand the vivid blue shade of their conspecifics.
This means that the beautiful colours of Chilobrachys natanicharum are utilized in spider-to-spider communication, however that may’t be discerned with for positive with out additional examine.

What we do know is that Chilobrachys natanicharum seems to be one of many rarest identified tarantula species, and that the mangrove forests it lives in are below menace of deforestation.
“The electrical blue tarantula demonstrates outstanding adaptability. These tarantulas can thrive in arboreal in addition to terrestrial burrows in evergreen forests. Nonetheless, with regards to mangrove forests, their habitat is restricted to residing inside tree hollows because of the affect of tides,” Chomphuphuang says.
“It is important for most of the people to know the importance of taxonomy as a elementary side of analysis. Taxonomy serves a significant position, starting from the essential, resembling when individuals inquire on social media concerning the identify of a spider, to conducting essential analysis geared toward preserving these species from extinction.”
A paper describing the species has been printed in ZooKeys.
