Sagot :

Answer:

Fish

Explanation:

  • Fish are animals that are cold-blooded, have fins and a backbone. Most fish have scales and breathe with gills. Approximately, 22,000 species of fish began evolving 480 million years ago. The largemouth bass illustrated above has the typical torpedo-like (fusiform) shape associated with many fishes.
  • Lateral lines are usually visible as faint lines running lengthwise down each side, from the vicinity of the gill covers to the base of the tail.
  • Fish live and breathe under water. They have scaly skin, fins to help them swim and they breathe through gills.
