💡 Everyday Comparisons for Size, Mass & Speed
- 💡 The optimal temperature for this group is 0–1°C, and it can barely survive above 20.5°C, meaning an indoor summer temperature of around 25°C is far too hot for it (Comparison).
- 💡 The mountain called Changbaishan in China is known as Baekdusan in Korea. The prefix 'Baekdu' in its Korean name appears to come from its being known from around this mountain (Comparison).

🇰🇷 4. Connection to Korea
It is listed under the Korean name 'Baek-du-gwi-ttu-ra-mi-but-i' (Korean name) on the National List of Species of Korea of the National Institute of Biological Resources (NIBR).
