The Fathead Sculpin (also known as the Blob Sculpin) is a large marine sculpin. They have big heads and tapering bodies that end in a small, flat tail, giving them a body shape similar to tadpoles. The fish doesn’t have scales but is covered in soft spines. They have large pectoral fins.

As adults they are bottom-dwelling, spending their time on the seafloor. They can grow to be more than a meter (3.28 feet) long, and can be nearly the same in width.
