Loch Nestor

Trivia

 * Loch Nestor derives its name from the Scottish lake, Loch Ness, which is the home of the famous and mysterious Loch Ness Monster, also known as Nessie. Probably Loch Nestor was named after the Loch Ness Monster. The name Loch Ness has been mixed with the name Nestor (a given name), to create this fish's name.
