In condensed matter physics, scanning SQUID microscopy is a technique where a superconducting quantum interference device (SQUID) is used to image surface magnetic field strength with micrometre-scale resolution. A tiny SQUID is mounted onto a tip which is then rastered near the surface of the sample to be
Perhaps the best video of a live colossal squid is that of an animal recorded at the surface in the D'Urville Sea off Antarctica in January 2008. [21] The squid was pulled to the surface feeding on a line-caught toothfish. The video is likely the first to show a colossal squid swimming freely, and records the animal performing a slow roll on ...
When the glass squid keeps the sacs closed, its body is see-through, making it invisible to predators and prey. The sacs look like tiny polka dots covering its translucent body.
The list includes records of giant squid (genus Architeuthis) either supported by a physical specimen (or parts thereof) or—in the absence of any saved material—where at least one of the following conditions is satisfied: the specimen was examined by an expert prior to disposal and thereby positively identified as a giant squid; a ...
Bigfin squids are a group of rarely seen cephalopods with a distinctive morphology.They are placed in the genus Magnapinna and family Magnapinnidae. [2] Although the family was described only from larval, paralarval, and juvenile specimens, numerous video observations of much larger squid with similar morphology are assumed to be adult specimens of the same family.
The average size of adult H. pfefferi is 100 mm (3.9 in) in mantle length (ML). The body consists of a large funnel with small paddle-like fins. They have small tentacles above their eyes. The funnel does not have valves, but contains a dorsal pad with three papillae as organs.
The squid giant axon is the very large (up to 1.5 mm in diameter; typically around 0.5 mm) axon that controls part of the water jet propulsion system in squid.
The bacteria are fed a sugar and amino acid solution by the squid and in return hide the squid's silhouette when viewed from below by matching the amount of light hitting the top of the mantle (counter-illumination). [13] E. scolopes serves as a model organism for animal-bacterial symbiosis and its relationship with A. fischeri has been ...
