At the Oregon Coast

“Don’t worry My mom is watching and will be back!”


Before you head out to the wonderful world of tidepools, please watch this video. It will help you to understand both how tough tidepool creatures are as well as how fragile. It’s easy to “love them to death” if we are careless about where we step as well as what we pick up. Watch, learn, and enjoy Oregon’s magical rocky shores!

It’ All Connected! Tidepools, Rocky Reefs, and Marine Reserves




SEA is also very concerned about the well-being of the marine life we are privileged to watch up close on our coast. While walking along the sand or exploring tide pools, you may come upon marine life or sealife such as a nest or baby that is so close that you can touch it.
Stay far enough away that the adults in the nest or close by do not act worried or get excited.

If you come upon a pinniped (seal or sea lion) pup, stay away. Mother seals occasionally leave their pups on the sand so that they can go feed themselves. They will return. Hanging around the pup will prevent the mother from returning.

Here are some basic rules to follow if you encounter a marine mammal. I have taken them from the Oregon Marine Mammal Stranding Network website. They are very clear and helpful. Please read and follow.

Stranding Dos & Don’ts

What to Do If You Find a Marine Mammal Ashore

Reporting marine mammal strandings promptly is the best way you can help stranded animals. Even dead animals provide a valuable opportunity for wildlife professionals to study marine mammals. Learn more about OMMSN research here . 

Harbor seal pups found on beaches are usually not stranded. Please keep dogs and people far away. Learn more about pup season here.

Marine mammals are protected by federal law. It is illegal for unauthorized persons to disturb, handle, or feed them.


  • Keep people and dogs away.
  • Observe and report the following:
    1. Identification: Note color, size, vocalizations.
    2. General condition: Is the animal alive or dead, lethargic, injured, bleeding, entangled?
    3. Colored tags: Seals are tagged on hind flipper, sea lions on foreflipper (can you safely read the tag number?).
    4. Location: Be as precise as possible, making note of landmarks and beach accessibility.
    5. If you find a live cetacean (dolphin, porpoise, whale), provide supportive care:
      • Protect animal from harsh wind or sun
      • Dig trenches for pectoral flippers
      • Rinse any sand out of eyes
      • Keep the area quiet
      • Make sure the animal is not too hot or too cold. Keep live cetaceans cool and moist by covering them with wet towels (if available) or gently pouring water on them. But be very careful not to cover or pour water down the blowhole (on top of the head). Report strandings of live cetaceans IMMEDIATELY.

  • move, touch, or disturb the animal
  • drive animals back into the water
  • pour water on a seal or sea lion
  • try to feed the animal

Some poorly understood facts about pinnipeds:

  • They are amphibious, at home on land as well as in water
  • They don’t need to remain wet
  • They do need to rest on land
  • They tend to move awkwardly on land
  • They are capable of extended periods of fasting
  • They should be left alone

It is important to keep in mind:

  • Human and domestic animal contact with marine mammals is only likely to cause stress, which can have detrimental health effects
  • Animals die through natural selection; it is a normal process
  • Euthanasia is sometimes an option to relieve animal suffering
  • Adverse weather and tidal conditions can be challenging and dangerous; responders should always prioritize human safety first
  • Marine mammals spark strong human emotions, potentially complicating effective stranding response
  • We all need to better educate the general public to share the shore with marine mammals
