MYSTERIOUS transparent jelly-like objects have washed up on the shores of Urangan, giving the appearance of hundreds of ice cubes scattered across the sand.
The unusual sight was captured by Fraser Coast Chronicle chief photographer Alistair Brightman this week.
But Hervey Bay is not in the grips of the next ice age.
Reefworld Aquarium owner Greg Wolff identified the gelatinous blobs as egg cases from the conical sand snail.
"If you look inside them, there are lots of little eggs, in a mass of clear jelly," he said.
"They are laid in estuary beaches and mud flats all around Australia."
Mr Wolff said while they were most common during summer months, it was not unusual to see them all throughout the year in Hervey Bay.
While they were commonly mistaken for a type of jellyfish and often avoided by beachgoers, Mr Wolff said the egg cases were harmless.
"They're not dangerous at all, they're just squishy," he said.
It is not known what caused the unusually large number of eggs to wash up this week.
