Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'coral colour' as 'кораллово-красный' when it is often a specific pinkish-orange hue. Do not confuse 'coral' (коралл) with 'coral snake' (коралловый аспид), which is a specific venomous snake.
Common Mistakes
- Using 'corals' as a plural for the substance (prefer 'coral' as a mass noun). Misspelling as 'corral' (an enclosure for animals). Incorrectly using 'coral' to describe any hard sea substance.

FAQ
Frequently Asked Questions
Coral is an animal. Each coral structure is a colony of thousands of tiny individual animals called polyps.
Bleaching occurs when stressed coral expels the algae that live in its tissues, providing it with colour and up to 90% of its energy. Without them, the coral starves and becomes vulnerable to disease.
In most countries with coral reefs, it is illegal to remove coral, alive or dead, as it damages the ecosystem and is often protected by law.
It typically refers to a range of pinkish-orange or reddish-pink colours, named after the natural hue of some precious coral species.
