'Mae' is at least 7.5m long with a sleek undamaged dorsal fin, a round, mature body and evidence of a male's bite marks on one of her pectoral fin and scuff marks on her pelvic fins. These marks may indicate that she has mated recently so her plump body may be hiding an interesting secret! We put her satellite tag on near a fantastic rock formation called the DRINKING DRAGON, Isle of Man. We didn't hear from her until November when she popped up in a familiar basking shark over-wintering area, the Celtic Deep. Very sadly it now appears that Mae may have been accidentally caught in a fishing trawl in the Celtic Deep as her satellite tag has now appeared in the fishing village of Greencastle in Northern Ireland.

Background

'Mae' is at least 7.5m long with a sleek undamaged dorsal fin, a round, mature body and evidence of a male's bite marks on one of her pectoral fin and scuff marks on her pelvic fins. These marks may indicate that she has mated recently so her plump body may be hiding an interesting secret!
We did a full basking shark passport on Mae, taking dorsal fin photos and a length estimate of 7.5m. We peeked beneath her with a pole camera to see if she was a male or a female and we took a tiny sample of skin slime to send to Aberdeen University for DNA analysis. Last but not least we put a beautiful shiny (and VERY expensive) satellite tag on her.
She is named Mae after team member Graham Hall's new granddaughter. Baby Mae weighed about 1 kg when she was born a few weeks ago whereas basking shark Mae probably weighs about 4000kg.
A BIG thank you to Sue Whittacker who was kind enough to let us know where this shark was.
