Intra- and Interspecific Foraging and Feeding Interactions in Three Sea Stars and a Gastropod from the Deep Sea
SIMPLE SUMMARY: Competitive interactions among animals come in a variety of forms and may be influenced by the size and number of the individuals involved, and whether these individuals are from the same species or not. The deep sea is a food-limited environment where it can be assumed that larger o...

The deep sea is a food-limited environment where it can be assumed that larger or faster scavengers might have an advantage over smaller or slower ones. However, very little work on competitive relationships in deep-sea megabenthic species has been done.

We measured food approach and consumption dynamics in interspecific and intraspecific trials with individuals of similar and differing sizes. Diverse competitive and cooperative behaviours occurred depending on the species, relative body sizes, and the number of individuals present. Surprisingly, larger or faster individuals (or species) did not always outcompete smaller or slower ones. In addition, some species changed their foraging based on competitive pressure, while others did not. Overall, this study sheds light on the feeding strategies of co-existing deep-sea invertebrates and the behavioural relations among them, providing important baseline ecological information for the comprehension of food web structures in remote and poorly understood environments.

SIMPLE SUMMARY: Competitive interactions among animals come in a variety of forms and may be influenced by the size and number of the individuals involved, and whether these individuals are from the same species or not. The deep sea is a food-limited environment where it can be assumed that larger or faster scavengers might have an advantage over smaller or slower ones. However, very little work on competitive relationships in deep-sea megabenthic species has been done. This study looked at four co-existing deep-sea invertebrate species of the Northwest Atlantic using time-lapse video recordings in controlled, darkened laboratory experiments. We measured food approach and consumption dynamics in interspecific and intraspecific trials with individuals of similar and differing sizes. Diverse competitive and cooperative behaviours occurred depending on the species, relative body sizes, and the number of individuals present. Surprisingly, larger or faster individuals (or species) did not always outcompete smaller or slower ones. In addition, some species changed their foraging based on competitive pressure, while others did not.
