An aquatic receptacle with a sectioned floating rim that, while floating, maintains an opening for receiving articles into the receptacle. Embodiments can include an escape barrier over the mouth of the receptacle to prevent loss of contents while floating. One embodiment has a lanyard that can attach the receptacle to a diver, allowing it to float and be pulled along by the diver. A lanyard can have a breakaway mechanism that can detach the receptacle from a diver or other structure if sufficient force is applied to the lanyard. There can also be a shock-arrest mechanism that reduces the amount of force exerted on a diver or structure before the lanyard breaks. Force exerted on the lanyard pulls the floatable rim at least partially beneath the water surface causing the sections of the floatable rim come together and close over the mouth of the container to prevent loss of articles within the container.
