Scientifically known as Chelmon rostratus, this butterflyfish is prevalent in the Indo-Pacific region, from India to Japan, and even as far east as Micronesia. The copper band, which runs diagonally across the body, is one of its most distinctive features. The copperband butterflyfish is known for its vibrant colors and intricate patterns.

5. Jellyfish

The moon jellyfish or Aurelia aurita is the most recognizable of the jellyfish species. It is known for its translucent, saucer-like body and the four neon-blue spots near the edge.
