TY - JOUR AU1 - Wallis, S. J. AB - the attachment area was horizontal until the epoxy set (3-8min). The animals were then lefi to recover. The resulting attachment is very strong because the transmitter matting and hair are all embedded in the epoxy producing a huge area of contact. The limitation of the strength of the attachment is that of the hair to the skin, and in non-moulting Grey seals this seems a very strong attachment indeed. The strength of the bond was made dramatically obvious when a bull seal copulated with a cow equipped with a transmitter only 30 min after application. Male Grey seals usually restrain the females they mate with, by taking a firm grasp of the skin on the females neck. In this case the bull used the new “handle” available to him, the transmitter, and took the radio tag between his jaws. He held the female so clasped for the 20 min or so of copulation during which the female occasionally struggled. The transmitter came through this unscathed, still firmly attached. Animals which returned to the rookery in 1981 after being equipped with trial dummy transmitters in 1980, showed no signs of the attachment.
