4 harbor seal pups due at Georgia Aquarium on Saturday

The downtown attraction is expecting to put four harbor seal pups on view Saturday in the Cold Water Quest Gallery, assuming their truck journey from SeaWorld Orlando goes smoothly Friday.

Born there last year, the four pups are between 3.5 to 4 feet long and weigh 86 to 114 pounds. Known for their prominent facial whiskers, they range in color from silver-gray to black to dark brown.

The seals are natural entertainers, spending half their time in the sea and half on land, when found in the subarctic and arctic waters of the North Atlantic and North Pacific oceans. They can dive to 1,500 feet while remaining under water for 40 minutes, though more typical is shallow dives of three to seven minutes.

They will “add a unique and diverse experience for guests,” predicted Billy Hurley, the aquarium’s chief animal officer.

Adult harbor seals can grow from 4 to 6 feet in length and weigh as much as 375 pounds. They feast on fish including flounder, salmon and rockfish.
