The original species of Amano shrimp came from the Ogasawara Islands, and people believe that Amano shrimp only came from Japan and its immediate vicinity, this is far from true.

In reality, Amano shrimp have also come from Taiwan, the Ryukyu Islands (between the Philippine and East China seas), Fiji and maybe even Madagascar.

These shrimp come from the streams and rivers flowing from mountains into seas and oceans.

They can also live in marshes and swamps.
