Flatfishes: Metamorphia event during development Bilaterally symmetrical larva to asymmetrical juvenile and adults. Horizontal instead of vertical!
Tetraodontiformes: Resembles Tetrapods
Vertebral column is rigid and locomotor activity more forward on appendages and less on motions of the trunk, Powerful jaw and well developed dentition for eating corals
