Cephalopods display some of the most diverse and elaborate reproductive strategies in the marine realm. Their mating systems encompass behaviours such as sexual mimicry, dynamic visual signalling, ...
Cephalopods – including octopuses, cuttlefish and squid – possess one of the most sophisticated neural systems among invertebrates, which supports a wide array of complex behaviours. Their neural ...
However, a more sophisticated behavior has been observed, in which the cephalopod releases a cloud, with a greater mucus content, that approximately resembles the cephalopod that released it (this decoy is referred to as a pseudomorph).
