caption: The image shows a close up of a worm on the ground surrounded by mud and twigs. The worm appears to be a medicinal leech, with its long, thin body and segmented legs. Its head is slightly raised, and its eyes are wide open, giving it an alert and inquisitive look. Its body is covered in small bumps and its tail is curled around its body. The mud is a dark brown color, and the twigs are a light brown.
