(KHNL) - It's a rare event that has scientists surprised, and working overtime.
An endangered Hawaiian monk seal on midway atoll had twins!
It's only the fourth set of twins ever documented.
The plane left midway atoll early Saturday morning with precious cargo, two female monk seals, born in early april.
"The Hawaiian monk seal is one of the most endangered seals in the world so i think it's important to do proactive management," John Klavitter, US Fish & Wildlife Service.
The seals are now in Honolulu.
Several marine agencies are working together to raise the pups.
The undersized pups weaned 10 days ago. It is unprecedented that they have survived this long.
Their mother left them to fend for themselves and their chance of survival in the wild without assistance was minimal.
I will be a first, if these twins survive and are successfully reintroduced back into the wild.
