First of all, according to the classification of legs-eight legs and six legs-two kinds.

Suppose all 36 are 8 legs.

36*8=288 legs

288-236= 52 more legs than the actual one.

Replace the hypothetical 36 8-legged-1 8-legged ones with 1 6-legged ones, and only subtract 2 legs.

52(8-6)= 26-6 legs

There are 36-26 crabs with 8 legs = 10.

Suppose all 26 hexapods are dragonflies.

26*2=52 pairs

More than the actual 52-40= 12 pairs.

There are 12 cicadas (2- 1) = 12 cicadas.

There are 26- 12= 14 dragonflies.

A: Crab 10, cicada 12, dragonfly 14.
