"Scleroparei" is an outdated taxonomic grouping that once included fish with bony plates on their heads. 💀 It's like an old version of software that's no longer used. This term is rarely used in modern classification systems. Fish formerly classified as Scleroparei are now placed in different groups based on more accurate evolutionary relationships. Understanding the history of classification helps us appreciate how scientific knowledge evolves. Think of it as the history of biology!
