What is scientific name crocodile?

The scientific name for crocodiles is Crocodylidae. This is the family name, not the name of a specific species, because there are many species of crocodile.

Scientific naming is a way of classifying animals into groups. For example, crocodiles are animals (not plants or bacteria) so they are part of the Kingdom Animalia. Crocodiles have spines-- they're vertebrates-- so they are part of the Phylum Chrodata. Crocodiles are reptiles, so they're part of Class Reptilia. The family name, Crocodylidae, is the group right above specific species in the hierarchy of scientific naming.
