QUINCY (CBS) – A boat was headed out Friday night to release 10 endangered sea turtles back into the wild.

The 10 turtles, five Kemp’s Ridley and five green sea turtles, all stranded themselves on Cape Cod last year.

The New England Aquarium’s Tony Lacasse says these turtle standing’s happen often.

“These are the hardest cases. Three of these particular turtles had a lot of shell trauma and had to either have their shells cast or surgically put back together,” said Lacasse. “And they’re ready to go.”

Workers at the New England Aquarium’s Animal Care Center in Quincy spent eight months nursing the animals back to health.

They’ve recovered from hypothermia and other injuries and they’re ready to go free.

Scientists have glued satellite tags to the turtles’ shells so they’ll be able to track the reptiles.
