‘Pisces’ is a traditional classification group that includes all fish. Dogfish (a type of shark) is a cartilaginous fish belonging to the class Chondrichthyes, which falls under Pisces. Jellyfish belong to the phylum Cnidaria, Silverfish are insects belonging to the phylum Arthropoda, and Starfish belong to the phylum Echinodermata. None of Jellyfish, Silverfish, or Starfish are fish (Pisces).
Pisces includes all true fish (aquatic vertebrates with gills, fins, and typically scales). Many organisms with “fish” in their name are not true fish.
