FIGURE 7 in Politolana sanchezi sp. nov. (Crustacea: Isopoda: Cirolanidae), a new benthic bioturbating scavenger from bathyal soft-bottoms of the southern Bay of Biscay (northeastern Atlantic Ocean)
FIGURE 7. Bioturbation of surficial sediments related to the scavenging behaviour of benthic crustaceans (mainly represented by the isopod Politolana sanchezi sp. nov.) during a 12h TFS night trophic experiment on the Cantabrian continental slope (15–16/04/2004, 602 m depth). A: photo n°1 (20h18) showing the initial bottom aspect with regular ripple marks at the beginning of the sequence. B: photo n° 20 (23h30) showing numerous isopods attracted by the baited fish of the trap, the disappearance of ripple marks in the area close to the sledge where the bioturbating activity of scavengers is maximal, the cloudy aspect of the near-bottom water just above the bioturbated area due to the presence of resuspended muddy bottom particles.
