The worm "smelled to high heaven," says photographer Darlyne Murawski. "It was full of blood." Such parasites, called trematodes, take up residence in other animals, feed on and reproduce within them, and then either kill the host or escape. Their bodies are almost entirely dedicated to reproduction.Darlyne A.

Voracious predators that hide under rocks in intertidal zones or in the open sea, many are equipped with neurotoxin-tipped barbs on their proboscises for impaling other worms, their main prey. One of the toxins found in ribbon worms, anabaseine, shows potential for the treatment of Alzheimer's disease. (This species, Baseodiscus delineatus, had not been seen before in Hawaii.)Darlyne A.
