Where can we buy these live hum from? Any specific locations to
recommend? 
Are they still able to survive after so long out of the sea?
Where should we release them? surely not on the beaches
sometimes i see them on the shelves of NTUC/Cstorage in the chiller
department.
If you put them into the water and see the hum breathing with
bubbles, they are alive.
Most will open their shelves slightly in the water after a
while.
Can release them near the rocky part of the beaches, they lived
clinging onto the rocks. Or near any sewage portholes flowing into
the sea. If can't find, release them into your mouth
and later do a bardo prayer for them. ( joking ha).
hahahah...
