- Harbor seals are the most abundant seals found in New York State.
- Their average dive time is three minutes, although they can stay under water for up to 30 minutes!
- Harbor seals have a thick, insulating layer of blubber. They can slow blood flow to their skin to keep from losing heat to the cold water or air.
- Their large eyes, acute hearing, and sensitive whiskers help them hunt for prey.
- They have no tears, but mucus continuously washes over their eyes to protect them from saltwater. When on land, this mucus gives them a teary-eyed appearance.
Male harbor seals average 5-5 ½ feet in length and weigh 200-250 pounds. Females are typically smaller, about 4 ½ to 5 feet in length and weigh 150-200 pounds.
A rounded body with a spotted coat ranging from silver-gray to black or dark brown. They lack external ear flaps and have fan-shaped flippers.
Where to watch:
They spend their time in coastal oceanic waters and can be found basking on sand bars, rocks, or remote beaches during low tide within estuaries, bays, and rivers. When resting in water, their heads bob at the surface resembling a floating bottle and thus is termed "bottling."
When to watch:
When watching seals, stay back about 150 feet in order to prevent unnecessary stress and abandonment of their basking sites. Approaching seals can cause them to feel threatened and they may bite. If a seal appears injured and in need of help, keep your distance and report to the NYS Marine Mammal and Sea Turtle Stranding Program at 631-369-9829.
