💡 Everyday Comparisons for Size, Mass & Speed
- 💡 A colony height of about 19 cm is close to the short side of an A4 sheet of paper (21 cm) (Comparison).
- 💡 Because it is known to live only around Jeju Island in Korea, water temperature changes and leisure activities in Jeju waters directly affect the survival of this species (National Institute of Ecology).
