Recent ecological studies have revealed that feed- ing-habit groupings may not be sharply delimited. Criconemoides. While some nematodes are free-living, others are parasitic and need other organisms (called hosts) to keep themselves alive 3.Once attached to their host, they divert nutrients and feed off of blood, tissues or pieces of cells to facilitate their own growth.
