Sample text

However, notwithstanding the rapid increase in deep‐sea knowledge that has occurred in the last few decades, it is evident that we still have much to learn to address even the most basic questions and more sampling is needed (McClain & Mincks Hardy, 2010). In this chapter, the main deep‐sea faunal groups, their adaptations and their distribution patterns will be briefly reviewed with the aim of introducing the following book chapters, where the gears and the techniques used to study and sample deep‐sea organisms are described.

2016 John Wiley & Sons, Ltd. Published 2016 by John Wiley & Sons, Ltd. 1 A pictorial representation of the life in a deep sea canyon presented in the February 1953 issue of Life magazine. The original legend stated: ‘Canyon’s mouth at base of a continental slope, jellyfish, viperfish, sea devils, sea cucumbers, quill worms move through lightless depths a mile below last glimmer of sun. Cataract in background is a slump of seaslide of green mud and sand, similar to one that broke the Atlantic cables in 1929’.

E. rely on food particles deposited on the seafloor) and may actively move for short distances in order to reach and exploit a new area. Several deep‐sea species that live permanently in the water column or occasionally swim to reach another foraging ground have developed gelatinous body structures to enhance floatation and passive transport by bottom currents. These adaptations allow for a considerable reduction in the amount of energy necessary to move to another feeding ground. One of the best examples of this behaviour is that of the cirrate octopods Cirroteuthis and Grimpoteuthis, which have well‐developed webs and semi‐ gelatinous bodies that allow neutral buoyancy and an ‘umbrella‐style drifting’ to take advantage of near‐bottom water currents.
