Do goldfish have teeth? How to eat?

Goldfish do not have teeth like humans, only pharyngeal teeth. Their pharyngeal teeth are small and difficult to detect. Goldfish are members of the Cyprinidae family, and their pharyngeal teeth are derived from the ceratobranchial bones of the gill arches. Because most of their pharyngeal teeth grow on the inside of the hypopharyngeal bone, they are also called hypopharyngeal teeth. The pharyngeal teeth of goldfish are constantly replaced and grown, so white pharyngeal teeth of goldfish can occasionally be found in fish tanks.

1. Do goldfish have teeth

? Goldfish don't have the kind of teeth we usually think of, so goldfish usually swallow food. But goldfish have pharyngeal teeth, also known as hypopharyngeal teeth. As a cyprinid fish, the fifth pair of gill arches of goldfish will derive some teeth-like bones from the ceratobranchia, which grow on the inside of the hypopharyngeal bone of goldfish, so they are also called hypopharyngeal teeth. With the growth of goldfish, the lower pharyngeal teeth

of goldfish will be replaced continuously, and the old pharyngeal teeth will fall off and new pharyngeal teeth will be formed. When raising goldfish, careful observation can occasionally find the white teeth of goldfish sinking to the bottom of the water in the fish tank. It is also because goldfish do not have normal teeth, can not bite, so goldfish is relatively mild, more suitable for viewing and breeding.

2. How do goldfish eat

? Because goldfish don't have normal teeth, goldfish can't bite. The lower pharyngeal teeth of goldfish have only simple chewing ability and can only be used to cut or crush food, which is why some aquatic plants in fish tanks break. Because the goldfish has no teeth to bite, it can only chew food with the lower pharyngeal teeth, so when feeding the goldfish, it is better not to make the bait too large or slender, it is better to crush the food, otherwise it is difficult for the goldfish to swallow.
