caption: The image shows a close up of a blue background with a black object in the center, which appears to be a nematode, a small, round, cylindrical organism with a long, thin body and a long tail. Its body is covered in small, dark hairs and its head is slightly tilted to the side. Its eyes are large and round, and its mouth is slightly open, revealing its small, white teeth. Its tentacles are long and thin, and it is surrounded by a halo of light.
