'Mambo' was rescued at Fort Doyle in Guernsey on Saturday.
The seal pup has a chest infection and discharge and is now in the intensive care area for seal pups at the GSPCA.
Geoff George, Head of Marine Mammals said
We certainly don’t expect to have to rescue a 5th seal pup on the weekend. We have rescued local pups through January but to need help in February is very late. We’ve called the new pup Mambo and we are all doing all we can for this very poorly pup. Sealia, Andy, Marty and Gully are improving daily and two of them are now out on our pools.
