Multiple Choice

The following questions refer to the description below.
Terry catches a ray-finned fish from the ocean and notices that attached to its flank is an equally long, snakelike organism. The attached organism has no external segmentation, no scales, a round mouth surrounded by a sucker, and two small eyes. Terry thinks it might be a marine leech, a hagfish, or a lamprey.

• A) It has mucus on its skin.
• B) If it had an ectoparasite, then it must also have endoparasites.
• C) The bite of the hagfish introduces paralytic neurotoxins, which Terry wants to avoid.
