The degradation rate is very slow in ambient temperatures. A 2017 study found that at 25 °C (77 °F) in seawater, PLA showed no loss of mass over a year, but the study did not measure breakdown of the polymer chains or water absorption.[55] As a result, it degrades poorly in landfills and household composts, but is effectively digested in hotter industrial composts, usually degrading best at temperatures of over 60 °C (140 °F).[56]

Microplastics weren't enough, let's give the sealife macroplastics.

This is probably PLA, which is compostable.

It's industrial compost though, not backyard compost. Important distinction IMO that micro plastic could still be an area of concern

It is PLA, which is aquarium safe.

How else will they learn to use the micro plastics?

Some people have a lot of free time.
Nevertheless, that's cool.

Sometimes, the right way. A lot of times, though, they're upside down or sideways.
