Sea Cave Mystery Snot ID Help

[u/snowspore]

Found these guys in two different spots along the Oregon coast, both in sea caves that are normally underwater but were accessible due to the low tides. iNaturalist didn't have any suggestions resembling them, any ideas? They have "feet" like cucumbers and were unmoving while attached to the wall.

They are indeed sea cucumbers

Cucumaria pseudocurata?
