Time lapse of kakahi filtering algae.

Sweet! Bob, watch the one in the lower right carefully. You can see the pseudofeces piling up at the anterior end of the incurrent aperture (the lower end as oriented in the picture…). Then you can see the excurrent aperture closes just before it ‘coughs’ to blow them away.

I love this, thank you.

[@iskandermakhmudov]

So you put them in a water tank and they will filter through muddy water?

[@CallemJayNZ]

Yup they are filter feeders, one mussel can clean one liter of water per hour
