To analyse the dna, they need fairly few specimen, as one body will already include gazillion strands of dna...

2. the high concentration of orks gives them a lot of biomass to swell the ranks...

Tyranids reqct to threats/opponents with mutation and adaptation. orcs are more muscular and have thicker skin and are more ferocius. that does not mean that the hive has taken that size from ork dna, merely that the warrior forms have been adapted to ork fighting. just like those that went to fight on an iceworld in the cain novels, adapted to the climate in successive gene rations.

ork psyche.. tyranids do not use tech and already have their synapse creatures as leaders.. aka follow the biggest ork.. slay that and the swarm around it becomes feral.
