This one walked onto my hand when placed in water. Small gatherings on rocks under weeds in & out of water bottom of beach. (Collective noun? A henge perhaps?) Care - soft bodied, probably rather fragile.
Underside rock nearby to picked up one, more room to leave in situ when replaced rock
These were very abundant.
is this a different one from the red beadlets?
I found 2 but forgot to photograph the second.
Absolutely beautiful animals.
These things are adorable
