Scientists rely mostly on beached corpses or bodies found in whale stomachs to study the elusive giant squid.
Furthermore, the region in their optic lobes that integrates visual information with motor tasks is reduced, implying that giant squids don’t rely on visually guided behavior like camouflage and body patterning to communicate with one another, as other cephalopods do. As usual, you can also use...
The eyes of giant and colossal squid are among the largest eyes in the history of life. It was recently proposed that sperm whale predation is the main driver of eye size evolution in giant squid, on the basis of an optical model that suggested optimal performance in detecting large luminous...
Hodgkin and Huxley’s five papers in 1952 were the capstone to this effort. The first of the five papers provided a description of the electrical behavior of the membrane of the squid giant axon under control conditions. The second paper examined the effect of changing the concentration of Na...
Friday Squid Blogging: Giant Squid Video A video—authentic, not a deep fake—of a giant squid close to the surface. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my blog posting guidelines here. Tags: squid, ...
(Hodgkin & Huxley, 1952a,1952b,1952c), studies of the squid giant axon have contributed significantly to our understanding of the nature and function of neuronal ion pumps, Na+, K+, and Ca2 + exchangers and channels (Altamirano, Breitwieser, & Russell, 1999; Llinas, 1982; Westerfield & ...
The power scaling of laser devices can contribute to the future of humanity. Giant microphotonics have been advocated as a solution to this issue. Among various technologies in giant microphotonics, process control of microdomains with quantum mechanical
“Even more disturbing, it had a prefrontal cortex, the part of the brain that deals with cognition, planning and regulating social behavior. This lobster had the ability to think and plot revenge. “Some kind of rapid evolution is going on in the lobster world. And it’s not a stretch ...
It’s the largest giant squid ever recorded—although scientists now think that the size was an exaggeration or the result of postmortem stretching—and there’s a full-sized statue of it near the beach where it was found. As usual, you can also use this squid post to talk about the ...
January sixth was the terrorist acts, and the treasonous behavior. The plotting and preparing for another act of treason using the tools of terrorism and sedition is ongoing… The ironic thing is what someone had continued to say on the campaign, signaling from the White House lawn on the ...
