A seal has been spotted 17 miles inland in Somerset in southwest England.<br /><br />Nature photographer Carl Bovis got the surprise of his life when he found the harbour seal in a field during his morning walk on Sunday (August 5). <br /><br />The seal was spotted by Bovis basking in the sun 17 miles up the River Parrett.<br /><br />Bovis later wrote online: ''I couldn’t believe it when I saw it.<br /><br />''The seal seemed perfectly happy though, enjoying the sun as it lay on the muddy riverbank. <br /><br />''Even more unusual is the fact that Harbour Seals are rare on the Somerset coast.''
