While oysters lack ears, they still can hear, using statocysts, their balance organ. Researchers have found playing the soundscape from a healthy oyster reef attracts larvae to settle! They have evolved to settle on their ancestors to build reefs, and sound is a useful cue of a good spot! https://phys.org/news/2022-10-sea-soundscapes-summon-thousands-baby.html #clamFacts
Playing sea soundscapes can summon thousands of baby oysters, and help regrow oyster reefs

Imagine you're in a food court and spoilt for choice. How will you choose where to eat? It might be the look of the food, the smell, or even the chatter of satisfied customers.

@dantheclamman that's really neat that the larvae vibe to good sounds. I do wonder though, oysters don't have ears but use their balance organs for hearing and we use our ears as balancing organs, is this a coincidence? Or are balancing and hearing linked functions?!
@shom yes, I don't think they're always linked, but in this case it's convergent! Our liquid filled inner ear and the statocyst, a rolling little ball in a pouch, are both good at the double purpose of detecting gravity and sound :)
@dantheclamman that's so neat (and squishy), thank you.
You go you little ball in goopy pouch, thanks for the beats and balance!
