Ambushing, luring, stalking and pursuit, speculative hunting and hunting in disguise, among others are known modes of hunting in cephalopods. Cannibalism and scavenger behavior is also known for some species and the development of current culture techniques offer evidence of their ability to feed on inert and artificial foods.

2023年10月23日 · Cephalopod fisheries play an important role in food webs and human consumption, with extensive interest in aquaculture and conservation. In addition to exploring the unique neurobiology of these creatures, future research will also focus on how changes in the environment and overfishing endanger these populations.

2004年8月11日 · Cuttlefish engage in a relatively fixed sequence of hunting behaviors, which include attending, orienting, positioning within striking distance, and finally striking with the tentacles (Messenger 1968). They are decapods, possessing eight arms and two tentacles.

To investigate associative learning in a different cephalopod, six sexually mature cuttlefish (Sepia officinalis) participated in a counterbalanced, within-subjects, appetitive, classical conditioning procedure. Two plastic spheres (conditioned stimuli, CSs), differing in …

2017年8月17日 · Ambushing, luring, stalking and pursuit, speculative hunting and hunting in disguise, among others are known modes of hunting in cephalopods. Cannibalism and scavenger behavior is also known for some species and the development of current culture techniques offer evidence of their ability to feed on inert and artificial foods.

2019年2月18日 · The hunting strategies used by cephalopods varies within and between species and include ambushing, luring, stalking, pursuit, speculative hunting, and hunting in disguise (Hanlon and Messenger 1996). Once prey is captured, some cephalopods inject toxins into their prey to immobilize it (Hanlon and Messenger 1996; Villanueva et al. 2017).

In general, they are hunted (and eaten) by predators that are fast-swimming and hunt by sight. This includes sharks, bony fishes, marine mammals and seabirds, as well as other cephalopods. Most of the cephalopods' defenses are therefore visual in nature. Many predators also employ other senses when hunting, such as smell or a lateral line system.

2005年2月1日 · Through observation of interactions and eavesdropping of displays, group-living cephalopods or those with crawl-away young may learn to identify predators, improve hunting, and, late in life ...

2020年6月9日 · These studies suggest that decapodiform cephalopods employ similar visual hunting techniques, using either their eight arms, and/or their two fast-extendable tentacles to seize the prey. In the common cuttlefish (Sepia officinalis) hunting can normally be divided into three distinct phases (Messenger, 1968): attention, positioning, and striking ...
