KP2 was raised in captivity. He had been released but recaptured with the goal to relocate him this month because he was interacting with humans and had become too rough.

The cataracts means he’ll spend his life in captivity. The other two seals came to the aquarium under similar circumstances. One was abandoned by its mother at an early age and the other was starving and injured. None of the three would have survived in the wild, Rossiter said.
