Creeks are such interesting places, eh. Even if you just listen to the sound of water only it is magical. A study says it calms “emotions and relieving anxiety”. I think we all knew that. 🙂 Of course, I look at what’s in it as well.
Well, I brought one home as you can see with the close up movie. “Their simple nervous system is concentrated at the head end. Often there are 2 earlike flaps on either side of the head. There are often 2 primitive eyespots on the top surface of the head; they sometimes appear “cross-eyed.” The mouth is located about midway down the underside of the body; this is the only opening to the digestive tract. During feeding, a muscular, tubelike pharynx extends out from the mouth and sucks food into the animal. Tiny hairlike cilia on the underside, a thin layer of secreted mucus, and subtle muscular contractions account for their gliding movement.“
Physella acuta is a species of small, left-handed or sinistral, air-breathing freshwater snail, an aquatic gastropod mollusk in the family Physidae. Tadpole Snails are hermaphroditic (possesses both male and female reproductive organs). So mating with another is not required. However they can be “friendly” too as Jeanne called it.
The species is found all over the world. So some think it is of European origin, but others think not. Moreover genetic evidence suggests just the opposite. And so perhaps it was introduced from North America to Europe.
Wherever they are from, they are pretty. Additionally, both the Tadpole Snail and the freshwater flatworm means that the stream is healthy! Yeah!
