What is a blue animal?

Blue animals are: blue dragonfly, purple-blue macaw, blue-banded eel and so on.

The smell is very similar to dragonfly, but smaller than dragonfly. Smells are colorful, but blue seems to be the most common. Not dull blue, but rich and vivid blue, from deep cobalt blue to sapphire blue green. Heart spot green _ also called blue damselfly, is said to be "the bluest dragonfly".

Purple-blue macaw, with bright blue feathers and a huge beak like a hook, is distributed in Bolivia, Brazil and Paraguay in South America.

Eel with blue ribbon is the best among eels.

Fully developed adult eels exceed 1 yard (0. 9 meters) long and can live for 20 years. They are close relatives of the famous European eel, and they are also very popular with the rich who own large seawater aquariums.
