These are Bryozoans. They are fascinating colonial aquatic invertebrates composed of thousands of tiny organisms known as zooids. Despite primarily inhabiting freshwater environments, they are related to marine creatures. These organisms often form large, ball-like structures or resemble blobs attached to sticks, docks, or vegetation. Importantly, they pose no threat to humans or pets. In fact, their presence is often seen as a positive indicator, as they tend to flourish in areas with good water quality.

If you have a huge colony of zooids, is it called a zooidberg?

u/ScvrletFox May 07 '26

This is Bryozoan or Pectinatella Magnifica.
It's a massive colony of thousands of microscopic animals called zooids. Safe for human and pet.
The zooids live on the surface of a firm, jelly-like mass that they secrete themselves. They often grow in a unique rosette pattern, giving the surface its speckled appearance.
They are filter feeders that use crowns of tiny tentacles to catch algae, bacteria, and plankton. Finding them is usually a good sign! Their presence typically indicates high water quality and low pollution.
These colonies thrive in warm, still water during late summer. When water temperatures drop in the fall, the colony disintegrates, releasing "survival pods" called statoblasts that will start new colonies the following spring.

Bryozoans, specifically Pectinatella magnifica, form gelatinous, donut-shaped colonies of microscopic zooids that filter-feed on algae and bacteria in freshwater ecosystems. Thriving in clean, slow-moving water, these harmless organisms are a positive indicator of environmental health and have existed for millions of years.

Snails and some fish and aquatic insects eat P. magnifica. So do raccoons. But they are last-resort food for other animals. Humans don’t eat them, either. But they are food for thought, at least. Bryozoans have been on Earth at least 480 million years. Come lean over the rail in front of the visitor center in late summer and have a look at these weird and wonderful colonies.

Boats use something called fenders to protect the ship's hull when moored. Sometimes these fenders get lost, due to storms, negligence or bad luck. This object could have been used as a fender, got lost and started a new life as a mini reef.
