    It is well known that cuttlefish reared in aquariums are easily fed by dead animals (shrimp, crabs, etc). I wondered if they are any publications showing that cuttlefish might also use scavenging, as an alternative foraging tactics to active predation, in the wild. I heard that cuttlefish might feed on fish caught in nets, but there is no evidence if those fish were already dead or just moribund...Thanks :grin:

    Just found a very interesting RECENT work (Dec. 2005) from Chingis Nigmatullin that says that bottom and near-bottom species periodically are scavengers also.

    Furthermore, this author informs us that died organisms, ship´s discards and offal can be a source of food to some bottom octopods (e.g. Enteroctopus dofleini) and to a less degree sepiids and near bottom squids (e.g. Berryteuthis magister). They could be died fish, shrimps, crabs and cephalopods.

    Sorry for being a grey literature (but it is in English) but here it goes:
    Nigmatullin, Ch. M. (2005). Towards the correct methology of cephalopod feeding study: review of some neglected problems.
