Unidentified orb-ish light, almost jellyfish/ stingray like

We were taking out the trash. I looked up and saw a decently close, and pretty big object in the sky, freezing and telling my husband to look. We both stopped astonished. It was like a glowing orb, kind of a bluish star color. It almost floated through the sky as if it was floating through water with jellyfish type movements. With a shape that seemed to change but also almost move like stingray wings would. It wasn't an exact shape though. Started from north west, headed south east, in Sarasota Florida from the intersection of Fruitville and Lockwood towards Fruitville and Beneva, getting smaller and further back from view site pretty quickly. We've never seen something like this I've been looking everywhere for answers and I found nothing close to it!
