The first component includes at least one sensing 5 device arranged to sense at least one biological parameter associated with the host; and a wireless data transmitter arranged to transmit parameter data representative of the at least one sensed biological parameter. The apparatus also includes a second component comprising a wireless data receiver, the second component wearable by the animal host at a location on the animal host such that when the first component is 10 implanted into the animal host and the second component is worn by the animal host, the parameter data transmitted by the first component is receivable by the wireless data receiver. The second component also includes a data interface arranged to facilitate transfer of the parameter data from the second component.
