An amphipod (Hyperia macrocephala), a group of macroplanktons find a home in a small light bulb (6 cm in diameter). However, only access go inside bulb is less than 1 mm hole for filament cable but egg of many planktonic species are microscopic in size of 2-20 µm.
This demonstrates a good example of why we can't simply remove all debris from the ocean or shore. Many debris have come to shelter marine life, so it is harmful to them if we simply dispose of the debris they are in.
