Mushroom Corals; Fungiidae family.

Please do not take mushroom corals from the sea when scuba diving or snorkelling, and don’t buy their dead relations if you see them on sale in gift shops in Thailand (or anywhere else for that matter). Take only underwater photographs as memories – and leave only bubbles!

What you might call the true mushroom corals...

Like chunky mushroom corals that have been stretched out.

These corals are not really mushroom-like at all!
