Final answer:

The marine invertebrate worm described belongs to the Phylum Nemertea, known for bioluminescence and toxin production for defense and prey capture.


Explanation:

The worm described with a translucent body, bristled jaw, producing bioluminescence to ward off predators, and a toxin while attacking prey belongs to the phylum Nemertea, also known as ribbon worms.

Phylum Nemertea consists of marine carnivorous worms, predominantly benthic, feeding on various marine organisms. Some Nemertea species have unique adaptations like commensalistic relationships with mollusks and being sold as fish bait.

The distinction of Phylum Nemertea as part of the Lophotrochozoa superphylum alongside Mollusca and Annelida is based on their shared characteristics and evolutionary relationships within the animal kingdom.
