Two very separate phenomena are presented here.
1. The crab does not "know" to present a helmet design. only from a
large population are the few which look most like a helmet are chosen.
2. An already evolved plant has evolved mechanisms to seek those factors
which it needs for its individual survival (for the propagation of more
of its species), such as seeking water, and perhaps "smelling" and seeking
nitrogenous materials. These mechanisms include phototropism, geotropism,
and in vines seeking their support through reverse phototropism.
Neither implies a sixth sense in the sense of "knowing".

scientific explanations make sense to scientist but not always to non scientist.
For example we seem to be losing sight of the topic "sense"
Writers want to know "How" an organism "knows" it's surroundings.
How does the vine know. it's peers are being eaten. How does
the crab know to design it's nodules to discourage harvesting. How
did Amorphos morph their flowers to attract sprecific beetle to pollinate
each species. Isn't it wonderful that we have yet to unravel mysteries.
