What BBN said about it

  1. Hank Ledger · Lead AnchorThe New York Times says floating docks often have colorful sea creatures just below, so people lean over the edge to look for sea slugs.

  2. Hank Ledger · Lead AnchorLuan Roberts organized the first Docktober in twenty twenty-one, and this year's first meetup has now happened.

  3. Dr. Nina Byte · Tech & Science CorrespondentDoes this affect me? Because I would like to see one.

  4. Hank Ledger · Lead AnchorThe hammerhead doto is about ten millimeters long.

  5. Hank Ledger · Lead AnchorRoberts has watched docks in Washington for over five years, and she says she can count on one hand how many times she's seen one.

  6. Dr. Nina Byte · Tech & Science CorrespondentA hand. That's fewer sightings than I've had of my own keys.

  7. Hank Ledger · Lead AnchorAt one marina on Vashon Island, she says repeated sightings point to a stable population. She calls that quite unusual.

  8. Dr. Nina Byte · Tech & Science CorrespondentAnd what happens next? Do I bring a flashlight?

  9. Hank Ledger · Lead AnchorNobody has said. Thirty-five species on Vashon, according to iNaturalist, and this is the one people lie down for.

  10. Hank Ledger · Lead AnchorFive years, one hand, and ten millimeters. And they still lie down on the dock.
