💡 Everyday Comparisons for Size, Mass & Speed
- 💡 Its colony height of about 16 cm is about 3/4 of the short side of an A4 sheet of paper (21 cm) (Comparison).
- 💡 Because it is a coral living on bedrock at depths of 50–100 m, it inhabits places deeper than recreational scuba divers usually go (National Institute of Ecology habitat depth).
Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.
