The use of cephalopod beaks in ecological and population dynamics studies has allowed
major advances of our knowledge on the role of cephalopods in marine ecosystems in the …

Abstract “Deep-sea” cephalopods are here defined as cephalopods that spend a significant
part of their life cycles outside the euphotic zone. In this chapter, the state of knowledge in …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Food web linkages, or the feeding relationships between species inhabiting a shared
ecosystem, are an ecological lens through which ecosystem structure and function can be …

We synthesized available information from ecological models at local and regional scales to
obtain a global picture of the trophic position and ecological role of squids in marine …

Cephalopods, especially squids, are believed to have a structuring role in marine
ecosystems as a link between different trophic levels, primarily due to their voracious prey …

Cephalopods are an important prey resource for fishes, seabirds, and marine mammals, and
are also voracious predators on crustaceans, fishes, squid and zooplankton. Because of …

The pilot whale Globicephala melas, the sperm whale Physeter macrocephalus, and the fin
whale Balaenoptera physalus are large cetaceans permanently inhabiting the …

The current knowledge about the ammonoid/habitat relation is reviewed and in part newly
interpreted. The autecology of ammonoids, such as ontogeny and habitat, based on …

Cephalopods (Mollusca: Cephalopoda) play an important role as keystone invertebrates in
various marine ecosystems, as well as being a valuable fisheries resource. At the World …
