To determine the class to which squid, cuttlefish, and octopus belong, we can follow these steps:1. Identify the Organisms: First, we need to recognize that squid, cuttlefish, and octopus are marine animals that are commonly gr
So what Godfrey-Smith is saying is that the squishy octopus has a nervous system which has some similarities to our own in that it's quite large. Neil And a large nervous system is a sign of intelligence. He goes on to talk ...
during male-male agonistic interactions in the squidSepioteuthis lessoniana, the expression of specific components (i.e. Dark arms, Dark fin margin) determines the winner of a contest and may act as a dominance signal. Moreover, a set of female-specific components...

A cephalopod is a kind of sea creature, like a squid or octopus. 头足类动物是一种海洋生物,像鱿鱼或者章鱼。 Oh, cephalopods, yes, of course. I know what a cephalopod is. 哦,头足类动物,是的,当然。我知道头足类动物是什么。 Of course you do. ...
and true squid are in the coleoid cephalopod subclass (including all but the genus Nautilus) with the octopuses. When we say the octopus, we do not really mean one species. The genus Octopus has about 100 species, and while the behavior of most of them remains completely unstudied, new ...
puzzlement. For decades, researchers have studied how certain animals evolved to be intelligent, among them apes, elephants, dolphins and even some birds, such as crows and parrots. But all the scientific theories fail when it comes to cephalopods, a group that includes octopuses, squid and ...
In coleoid cephalopods with ten limbs, like squid and cuttlefish, eight short arms are designed like octopus arms for stiffening and bending. The remaining limbs, a pair of tentacles, are organized to produce a strike by rapid elongation15. Their morphology simplifies the strike, which is a ...
O. vulgarisarm formation shows both, similarities to known model species as well as species-specific patterns of arm formation. Similarities include early uniform cell proliferation and actin-mediated cell dynamics, which lead to an elongation along the proximal-distal axis. Furthermore, the switch ...
