NSRI Kommetjie duty crew were activated following eye-witness reports of a seal and a Loggerhead turtle trapped in a fishing net washed ashore on the beach at Longbeach.
A spokesperson for the NSRI Craig Lambinon says members of the public walking along the beach had come across the two distressed animals and raised the alarm.
A rescue crew responded and was joined by two staff members of the Two Oceans Aquarium.
Lambinon says they found the two animals trapped in one net and it appears that they may have been drifting at sea for some time in what looks like an old and discarded fishing net which most likely washed ashore during the night in the storm.
He says the seal appeared most stressed but they managed to free both animals within about 90 minutes.
The seal immediately returned to the sea appearing to be unharmed and the turtle was transported to Two Oceans Aquarium.
Staff at the aquarium says the turtle is receiving good care and will be released back into the ocean soon.
