In Marion County Lake you'll find some of nature's most evolved creatures, such as Brenda Casanova and her husband.

"We come out here and boat and fish," she says.

You'll also find some of the least evolved. Casanova recently noticed some strange looking blobs in the water near shore. She didn't know what they were.  She thought they might be fresh water jellyfish. Casanova is an avid nature photographer, so she fired off some pics.

"I started taking pictures of them and sent them in to (KWCH 12 Eyewitness News), because I just found them interesting and wasn't sure what was going on," Casanova says.

It turns out they are a prehistoric animal called a bryozoa. There are actually 4,000 different species of these creatures, although most live in tropical environments. They feed on what they can filter out fo the water, including algae. Experts say the animals are harmless, and when you see a lot of them that means the water quality is good.  They are not as common in Kansas lakes as they used to be.
