Coral bleaching vs mortality

When the ocean get too hot, corals expel the zooxanthellae algae that lives in their tissue.

In Western Australia, the damage to coral reefs including the World Heritage-listed Ningaloo has eclipsed any previous bleaching events.

These microorganisms give corals their bright pastel colours and disease resistance.

Their absence creates the bleaching effect many Australians have become all too familiar with.

Mass coral death at Ningaloo Reef

A fresh survey of eight sites along WA's Ningaloo Reef has revealed more than 60 per cent of corals have died.

Record water temperatures caused widespread bleaching last summer.

Of the 1,600 corals counted in March [last year], only 600 were still alive come late October.

'Hope spot' to 'skeletons': #Ningaloo's 'catastrophic' event
#2024 was the warmest year on record for global oceans, culminating in the fourth-ever global #coral bleaching event, which has circumnavigated oceans in a wave of ongoing coral mortality.
It hit Ningaloo late last year.
“In around December 2024, we started to notice that water temperatures were abnormally high,” says molecular ecologist Dr Kate Quigley.
