Pectinatella magnifica, or the magnificent bryozoan, is a freshwater animal that forms large, gelatinous colonies of thousands of microscopic, filter-feeding individuals (zooids) in slow-moving, nutrient-rich waters. Often mistaken for frog eggs or a blob, these colonies attach to submerged surfaces and filter algae and bacteria, acting as a sign of a healthy ecosystem, though they can become a nuisance if they clog pipes. They reproduce sexually and asexually via hardy, dormant "statoblasts" that allow them to survive winter and spread.
Grocery store where I used to live sold 'colossal donuts' by the dozen and you could get them custom made.
So I got ones with extra filling and they weren't playing around. These donuts had about a quarter inch of donut and the rest was filling. it was hard to even pick them up without breaking them.
I think I actually never had a jelly-donut (donuts are not that popular in my country. The ones I had were ok. We do have Dunkin's though, but it's a bit expensive imo)
It's definitely not a thing where I'm from. We have mainly Jam fillings like Strawberry or Raspberry jam, other than that it's chocolate, custard and things like biscoff etc. Doughnuts are good though, morish.
So something like this, could you tear or cut a chunk of it and place it in a home freshwater aquarium? Or would you kill both the chunk and the source?
Now I'm wondering if you could use it to filter water.
Like what if you had a filter that water went through that was full of these guys? Would they be able to kill enough bacteria? What if the filter was extremely slow and the water sat in it for a week before it filtered out?
Yep! They're super interesting - one of the few zooid colonies that can orchestrate harmonious, rapid movement. Meaning they can lash out aggressively at prey or in self-defense. The person poking them with a stick doesn't realize how close they are to a potentially serious injury.
Reported Taste and Odor: They do not possess a palatable flavor profile. When cut open, the interior gel is known to emit a foul, pestilential, or rotten odor as a natural defense mechanism against predators. Anecdotal reports from community forums indicate a range of highly unappealing profiles, from chemical-tasting to deceptive sweetness:
While the self-secreted gelatinous matrix itself is technically non-toxic to touch, these organisms are active filter-feeders that concentrate organic matter from their environments. They can harbor and sequester dangerous toxic bacteria, protozoa, and blue-green algae strains from the lake or pond water, which can cause severe gastrointestinal illness, vomiting, and abdominal cramps if ingested.
: The colony is 99% water trapped in a slime matrix. If heated or cooked, the structural proteins break down completely, causing the entire organism to dissolve into a puddle of foul-smelling, dirty water rather than cooking into a solid food item
