The term UNUSUAL FISH can be solved by the 8-letter word SEAHORSE. Seahorses are a type of fish that are easily recognizable due to their unique shape and size. They have a long, thin body with a head that looks like a horse, hence the name. They also have a prehensile tail which they use to cling to seaweed and coral. Seahorses are found in shallow tropical and temperate waters around the world. They are considered unusual because of their unique appearance and behavior.
