Morphology

boa + constrictor

The compound meaning is directly derivable from the parts: 'boa' (a large constrictor) + 'constrictor' (a snake that kills by constriction) simply names that type of snake. This noun–noun composition is literal and cross-linguistically regular, so a B1 learner who knows both constituents will readily understand the phrase.

Etymology

Boa constrictor gets its name from how the snake kills: the word constrictor means one that 'squeezes'. Imagine a large snake wrapping its body around an animal and slowly 'squeezing' it until it cannot breathe, so the name describes the snake's way of killing.
