Photographer Paul Goldstein recorded photographs of the chase while sitting on an icebreaker ship at Spitsbergen, Norway.
Paul said: "A bear mother and her children of about 18 months of age swam right under the bow. At that time we still did not know that the bear family was in a dangerous situation when being chased by a male bear. They continued to swim right under the ship, and then we saw the big male bear who was trying to turn the cubs into breakfast. '
Polar bears are very voracious species. In addition to fish, seabirds and seals, polar bears can even eat the same kind.
The male bear observed the mother bear and two cubs from behind an iceberg
The three bears plunged into the water to escape the hungry male bear
The male bear looked helplessly at the escape
After the hurried escape, the bear family stopped to eat
The baby bear and the mother bear are still careful to keep an eye on the predator
See if the male bear is still active
Even when going to shore, the bear still did not take his eyes off the man who was chasing his family
