Dine with the fishes at world's largest all-glass underwater restaurant

(CNN) — A warning to travelers heading below sea level to dine at luxury Maldives resort Hurawalhi's 5.8 Undersea Restaurant.

Your manners will likely be left up on the surface -- along with your shoes.

Cutting off one's companion mid-sentence is almost a certainty as you rush to point out one of the remarkable sea creatures swimming by, whether it's a reef shark or -- if you're lucky -- an octopus.

You might even find yourself giving your dining partner the silent treatment, mesmerized by the marine life that have made the stunning coral reef their home, from colorful parrot fish to moray eels and tiny mantis shrimp.
