Giant ray photobombs aquarium cleaners

Staff at an aquarium in London have set to work on their annual underwater spring clean.

Sea Life London houses more than 6,000 different species of sea life, including a octopus, clownfish, seahorses, and even a crocodile.

One giant ray jumped into a photo with its keeper while he cleaned the tank's glass.

It's risky work scrubbing away algae in the shark tank

A keeper collects shark teeth from the bottom of the tank. Many species of shark can lose one or two teeth every week, and new teeth grow roughly every two weeks
