Friday Squid Blogging: Squid vs. Owlfish
This video is pretty fantastic:
The narrator does a great job at explaining what’s going on here, blow by gross blow, but here are the highlights:
- Black-eyed squid snares owlfish with its two tentacles, which are tipped with hooks and suckers, and reels it in.
- Black-eyed squid gnaws away at the owlfish’s spinal cord using its very sharp beak.
- Owlfish is wearing a suit of large, shaggy scales, which it proceeds to shed in an effort to loosen the black-eyed squid’s eight-armed grip.
- Owlfish’s scale trick doesn’t work, squid burrows deeper into its back muscles, rotating it around [like] a cob of corn
- Owlfish dies with a gaping, red, meaty hole in its back and the drinks are on black-eyed squid because he’s feeling pretty great right now.

Friday Squid Blogging: Giant Squid Caught by Japanese Fisherman
It’s big: 13 feet long.
The fisherman was stunned to discover the giant squid trapped in his net, having been caught at a depth of around 70m, about two-thirds of a mile from the coast.

Friday Squid Blogging: Camouflage in Squid Eyes
Interesting research:
Cephalopods possess a sophisticated array of mechanisms to achieve camouflage in dynamic underwater environments. While active mechanisms such as chromatophore patterning and body posturing are well known, passive mechanisms such as manipulating light with highly evolved reflectors may also play an important role. To explore the contribution of passive mechanisms to cephalopod camouflage, we investigated the optical and biochemical properties of the silver layer covering the eye of the California fishery squid, Loligo opalescens. We discovered a novel nested-spindle geometry whose correlated structure effectively emulates a randomly distributed Bragg reflector (DBR), with a range of spatial frequencies resulting in broadband visible reflectance, making it a nearly ideal passive camouflage material for the depth at which these animals live. We used the transfer-matrix method of optical modelling to investigate specular reflection from the spindle structures, demonstrating that a DBR with widely distributed thickness variations of high refractive index elements is sufficient to yield broadband reflectance over visible wavelengths, and that unlike DBRs with one or a few spatial frequencies, this broadband reflectance occurs from a wide range of viewing angles. The spindle shape of the cells may facilitate self-assembly of a random DBR to achieve smooth spatial distributions in refractive indices. This design lends itself to technological imitation to achieve a DBR with wide range of smoothly varying layer thicknesses in a facile, inexpensive manner.
