The moon is in
its last quarter and the ‘low’ tide is only about 8 feet—soon it will go down
to near 1’ – the ‘froth’ on the lower tidal pool caught my attention – green froth
floating on surface – so I went to where I knew a colony of Protomonostroma
was – sure enough it was wildly reproductive |

Easy to spot

Not
sure I can tell it when only vegetative but this is the only alga around that
‘sheds’ its reproduction as small chunks of thalli – they float on the tide
and presumably settle at similar tidal height – and presumably can ‘travel’
farther a field than if a single cell powered by own flagellae |
