Bryozoans, which resemble alien egg sacks, are actually beneficial creatures found in lakes in Texas. These gel balls contain zooids that filter out plankton and serve as a food source for fish, insects, and snails. Their presence indicates good water quality and they are harmless to humans.

While bryozoans may look scary, they are not harmful and should not be killed or removed from lakes or ponds. They play a vital role in maintaining the health of the body of water they inhabit. Despite their appearance, they are not alien creatures and do not pose a threat to humans.

Common sightings of bryozoans have been reported in the Sam Rayburn Reservoir and Toledo Bend Reservoir in East Texas. These creatures are important for the environment and should be appreciated for the positive impact they have on the ecosystem.
