Freshwater ghost sharks, also known as chimaeras or ratfish, are one of the most mysterious creatures in the sea. These rarely-seen fish inhabit deep ocean waters and often remain elusive to scientists studying them. While they were once thought to be a mythological creature due to their rarity, researchers now know that these animals exist — but little is still known about them. One thing that is certain though is what these strange and remarkable creatures like to eat! Freshwater ghost sharks generally feed on smaller fish, squid, crabs and other crustaceans, as well as mollusks such as clams and mussels. They have even been known to scavenge for food when necessary — so potential meals can range from dead whale carcasses to small fragments of organic material found at the bottom of the ocean floor. In addition to eating smaller prey items whole (or pieces thereof), freshwater ghost sharks may also suck their prey up through special tube-like mouths located near their eyes! This feeding method helps them capture unsuspecting prey without having to expend too much energy chasing after it. With this unique ability combined with its impressive size -- reaching up 4 feet long – it’s no wonder why freshwater ghost sharks are considered one of nature’s most intriguing marine species!
