Garden Slug | need ID help

Found this one in the nearby park. It was overcast evening and I was searching for macro subjects when I found this one. Very slow mover as it dragged itself along the ground. When scared did squeeze its body and reduced its length.

Abhishek, need your help for the ID.

Looks like a Garden Slug... not sure of the species. Did you photograph it from other angles too?

The details are nice. Good you used a higher ISO and aperture. Thanks for sharing.

Abhishek, did not get other angle of this one.

Holding the camera parallel to the subject and f9 has helped here. With the rainy seanson we are getting some interesting subjects. Thanks for sharing.
