Mysterious Jelly Blobs in Oklahoma Lake Explained
In March 2024, boaters at McGee Creek Reservoir in Atoka County, Oklahoma, noticed strange jelly-like masses clinging to submerged tree limbs. At first glance, the blobs looked alien and unsettling. However, experts quickly revealed a much more ordinary explanation.

Not So Mysterious After All
The Oklahoma Department of Wildlife Conservation (ODWC) confirmed that the masses are bryozoans, also called moss animals. These tiny, colonial creatures form groups made up of individual units called zooids.

How Bryozoans Form Blobs
Bryozoans appear gelatinous because of a chitin shell. Underwater, the shell feels soft; on land, it hardens. When conditions are right, bryozoans reproduce quickly, forming large clusters that can seem eerie to unsuspecting visitors.

A Sign of a Healthy Ecosystem
Far from being dangerous, these jelly-like colonies are a natural part of the lake’s ecosystem. They indicate clean water and balanced aquatic life, playing an important role in filtering the environment.
