Espèce Lucicutia grandis - Carte de distribution 4Issued from : M.M. Gowing & K.F. Wishner in Deep-Sea Res. II, 1998, 45. [p.2442 & 2446, Fig.3, 4].
Mean percentages of food categories in gut-contents of Lucicutia aff. L. grandis from the Spring Intermonsoon and late SW Monsoon.
Data from all animals analysed at each depth were combined. n = number of animals.

Nota: The animals were clearly detritivorous, feeding on a variety of type of particles. The presence of metazoan remains suggests that the copepods are omnivorous. While pieces of cuticle could have been ingested as molts, the cnidarian nematocysts were sometimes associated with tissue, indicating carnivory. The results indicate that the diet of the population of Lucicutia included aggregates of material that had sunk from shallower depths.Intact cells in the gut contents indicate at least two types of aggregates, one originating in the oxygen minimum and the other in surface waters.
The animals consumed gram-negative bacteria including metal-precipitating bacteria, aggregates of probable gram-positive bacteria, virus-like particles and large virus-lake particles.
