An adorable grey seal had to be rescued after becoming stuck at the top of a 10ft-high Second World War pillbox.
The RSPCA was alerted by an anxious passerby who noticed the injured mammal on a beach on Tuesday.
It is not clear how he became stranded but the seal is thought to have been stuck for more than 24 hours.
He became dehydrated due to strong sunshine as he lay on the large blockhouse on Fraisthorpe Beach in Yorkshire‘s East Riding.
Leanne Honess-Heather, an RSPCA animal collection officer, said: “The poor seal was clearly distressed and we could see he had injured his eye.
“Because he had been stuck up there for 24 hours, and had been exposed to the strong sun throughout the heat of the day, he was very dehydrated.”
She added that the size of the pillbox made for a challenging rescue but, with the help of RSPCA deputy chief inspector Claire Mitchell, Ms Honess-Heather was able to help the seal down.
They had to carefully manoeuvre him into a net, as they jointly supported his body weight.
The seal was later assessed at the Scarborough Sea Life centre, where it was discovered that his eye had sustained some trauma and was slightly infected.
Following treatment, he was released back into the wild on Wednesday.
Pillboxes are concrete guard posts, which are normally equipped with holes so that weapons can be fired through them.
