Collared Worm Salamander

The Collared Worm Salamander, known scientifically as Oedipina collaris, is a slender, elongated salamander belonging to the family Plethodontidae, the lungless salamanders. Oedipina collaris is characterised by its worm-like body form, extremely elongated trunk with many vertebrae, short limbs, and a long tail — morphological features that adapt the species for a burrowing or semi-fossorial lifestyle. As a plethodontid salamander, Oedipina collaris lacks lungs and respires entirely through its moist skin, making it highly dependent on humid environments. The species inhabits freshwater habitats, moist forests, and wetlands. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Worm Salamander is currently assessed as Data Deficient on the IUCN Red List, indicating that insufficient information is available to determine its conservation status accurately, and further research on the species' distribution and population trends is required.

Fly Agaric

ベニテングタケ（Amanita muscaria）は地球上で最も象徴的で広く知られる菌類であり、北半球の北方林全域に白いいぼのある鮮やかな赤い傘を広げる。童話のような外見とは裏腹に、ムシモールやイボテン酸などの強力な向精神性化合物を含み、中程度の毒性がある。シラカバ、マツ、トウヒと重要な外生菌根共生関係を形成し、無機栄養素と炭素を交換することで北方林の栄養循環に不可欠な役割を担っている。
