With over 20,000 different fish species living in the world’s oceans, saltwater bony fish are the most varied of all marine animals living in the sea. They can range in size from a 2-inch goby to the enormous ocean sun fish (or Mola mola), they can be brilliantly colorful to plain grey, can live solitary lives or school by the thousands, and can live in the shallowest of tropical waters to the coldest, deepest depths of the sea. There is no animal group on earth that can compare to the diversity of bony marine fish.
