The tags provide information on what the animals are doing when they are underwater. They also allow scientists to track the animals when they are at the surface. Tags can provide long-term continuous information on the behavior and movements of individual animals.

The tag detaches from the animal after a set period of time and floats to the surface, where it then transmits all of its data to a satellite, or the researcher comes along and collects it. This tag can record date, time, swim depth, water temperature, body temperature, energy expenditure and location.
How does tagging help with conservation?
Some of the other conservation benefits of tagging and tracking data include: Revealing key areas to prioritize for protection, such as mating, feeding or nursery grounds. Determining sites where sharks are most likely to interact with fishing activities.
What causes ear tags?
Some causes of an ear tag or pit are: An inherited tendency to have this facial feature. A genetic syndrome that includes having these pits or tags. A sinus tract problem (an abnormal connection between the skin and tissue underneath)
Why are calves not tagged?

Why do cows get tagged?
Ear tags are needed for animal identification. They make it possible for us to identify and keep accurate records about each calf, heifer, steer, cow and bull.

How do scientists track animals?
Scientists have been using VHF radio tracking since 1963. In order to use VHF radio tracking, a radio transmitter is placed on the animal. Usually, the animal is first sedated. … Once the radio transmitter is placed on the animal, it begins transmitting a signal to a radio antenna and receiver.
