Blob fish are not dangerous, but scientists know little about these fish. What they do know is that while blob fish are not dangerous, they are endangered.
According to Science News, the blob fish is endangered because of trawling, or fishing with a net. In an effort to bring notice to its plight, the blob fish was named the "World's Ugliest Animal" by the Ugly Animal Preservation Society.
Despite this title, scientists know very little about the blob fish. It is a deep water fish, which means that it lives from 2,000 to 4,000 feet below the surface of the water, and is found off the coasts of Australia and Tasmania. Because it lives so deep at such a great pressure, the blob fish is made up largely of a gelatinous material that allows it to float in water. Its lack of musculature and a skeleton allows it to survive at such great depths. Because it does not have a swim bladder, an organ found in most fish that is filled with gas and allows them to float in water, it can survive for a time at sea level, but it takes on a droopy, blobby appearance because it has no skeleton to hold it up.
