Wearable shark sensor gives new meaning to 'fintech'
Marine biologists have used a combination of instruments strapped onto and ingested by sharks in order to understand the predators' behaviour. Waterproof video cameras attached to bluntnose sixgill, Galapagos and sandbar sharks offered researchers a presumably beady "shark's eye" view of the ocean. An ingested sensor helped the researchers to track the digestion of the animals, monitoring where, when and how much sharks are eating. These were also fed to other large sea creatures, such as tuna.
