Mysterious Lake Discovery
Residents of Oklahoma found a mysterious sac-like “egg” hanging from tree roots by the lake. Locals quickly jumped to alien-related conclusions. However, scientists are now calming the community by explaining the true nature of this ancient creature.
Ancient Creatures Revealed
These creatures have found an ideal environment and are likely to be around throughout the summer. Locals initially discovered large, jelly-like sacs with hard exteriors hanging from tree roots, sparking thoughts of extraterrestrial origins or bad news. But scientists reassured the public that these were actually the reproductive systems of ancient animals predating dinosaurs.
Scientific Explanation
Locals posted their findings online, prompting comments about alien-looking eggs. However, scientists identified the creatures as bryozoans, simple organisms that have existed for hundreds of millions of years. The discovery is actually good news for the lake.
The Role of Bryozoans
Bryozoans clone themselves into large masses, filtering tiny particles from the water for food, thus cleaning the lake. Typically found in ponds and lakes, this time they were discovered in McGee Creek Reservoir, on the southwest edge of the Ouachita Mountain Range. Bryozoan clumps aren’t eggs or single animals; they are colonies of hundreds of tiny creatures banded together, each called a zooid.
Unique Characteristics
Zooids, only a fraction of a millimeter long, lack respiratory or circulatory systems but have a central nerve ganglion to respond to stimuli. These invertebrates possess both male and female reproductive organs, allowing them to self-clone and spread rapidly through clumps of cells called statoblasts. Each statoblast can reproduce asexually by breaking off from the colony, enabling rapid reproduction if conditions are suitable. The animals consume phytoplankton and bacteria in the water.
Ancient Lineage
Fossil records suggest bryozoans evolved from ancient marine worms, dating back as far as 470 million years, predating dinosaurs by over 200 million years.
Official Statement
The Oklahoma Department of Wildlife Conservation (ODWC) shared photos on social media, stating: “What is that??? If you’re out boating somewhere like McGee Creek Reservoir, you may notice these strange jelly-like balls hanging from submerged tree limbs. These are Bryozoans, and they’ll likely show up in large numbers this summer. Don’t be alarmed; these microorganisms are native and pose no danger to you or wildlife. In fact, they indicate good environmental quality and clear water!”
