klepto: Greek κλέπτης ("thief") and κλέπτω ("steal") + parasitos: παράσιτος ("person who eats at the table of another")
Meaning: The parasitic theft of captured prey, nest material, etc., from animals of the same or another species; such as the theft by a gull* of a featherwight GoPro camera from a tourist on the French Riviera.
*Possibly a European herring gull (Larus argentatus).
The gull video reminded me of another wild travel video shot by a sea turtle on a "stolen" underwater camera.
The sea turtle video is more likely a case of entanglement than of kleptoparasitism.
