Rusty seal

The red colouration seen in the animal on the left is usually due to iron oxide deposits in the guard hairs - is this colouration common on the Tees?

Seals

It wouldn't surprise me Gill as the rocks around Middlesborough are full of ironstone.

There's a famous breeding colony of common seals in the mouth of the Tees near Saltholme.

I wondered why it was that colour but thought it was natural variation- fascinating that is is likely to be from iron oxide deposits.
And yes these seals were at Saltholme.
