You are describing an extremely nutrient-rich food with no immediately apparent defence against predation. To the extent that it is difficult to understand how this could exist in the wild.

I suspect that this alga has some interesting and perhaps surprising defences, in line with its relatives. (And, that these may well impact on its taste)

For example, spirulina is said to be spiral because this allows it to spontaneously flee from approaching water fleas, with no active energy use: primarily depending on the laws of physics.
