A penis fish at an aquarium in Oregon, USA, has left its visitors flabbergasted because it resembles something that is very rude.

However, visitors took images of the fish and shared them on social media, leaving everyone amazed and shocked.

32-year-old Stephanie Walen saw the rockfish, which looks like a penis of a man, when she was visiting the Oregon Coast Aquarium in Newport, Oregon.

Walen, who is a grocery worker, took pictures of the fish as it swamps up a glass wall.

She said:

People were so flabbergasted and some quite mortified by my photos, I had thousands of people asking whether its a penis or a c**kfish.

Thousands of people reacted to the images that Stephanie shared on her social media accounts.

Many were shocked because it was their first time seeing such fish.
