Beschreibung:
Octopuses are known to be highly efficient at the extraction of flesh from their crustacean prey. Experiments on capture and handling of crabs (Carcinus maenas) by the octopus Eledone cirrhosa show that paralysis of the crab invariably precedes hole boring of the carapace. The time course of feeding is described and it is shown that the ingestion of crab meat does not occur before about 40 min after capture for this specific predator-prey interaction although crabs are paralysed after 1-5 min. Comparative observations on hole-boring behaviour are given for Octopus
vulgaris and O. dofleini. The results are discussed in relation to recent data on the
biochemical composition of the secretions of the posterior salivary gland.
