The fence between the railway and the cycleway would have stopped the seal from returning to the water once it had made it to the road, he said.
“It probably kept on wandering along looking for a gap in the barrier to get down to the water again, it had quite a fair way to go in either direction.”
While fur seals were not overtly aggressive, people should still be cautious around one, he said.
“They’re a lot more flighty than sea-lions so they get scared and scared animals are probably the most dangerous animal if they feel like they’re cornered.
“If the animal is sleeping and it’s to one side you can probably sneak past quietly and be fine, but if it’s awake and feeling threatened then read those signals and it’s probably a good idea to dismount from your bike and just walk.”
Cyclists should distance themselves as much as possible from the seal and place their bike between them should it lunge.
