What does a picture candiru look like?

The candiru, also known as the vampire fish, is a small, slender freshwater catfish native to the Amazon River basin. It typically measures around 2 to 5 inches in length and has a translucent, elongated body with sharp spines and a pointed head. Its coloration ranges from pale to brownish, allowing it to blend into its surroundings. Notoriously, it is known for its parasitic behavior, particularly its ability to invade the gill cavities of larger fish.
