Several freshness and spoilage indicators were monitored to characterize the postmortem biochemistry of giant squid (Dosidicus gigas) mantle muscle. Squid samples were obtained directly from the sea and kept at 0 °C during a 15-d storage period. Data at zero time were obtained from cryogenically frozen samples at time of capture. The adenosine 5'-triphosphate (ATP) degradation followed a different pattern as compared with that from fish species. ATP was almost completely depleted at 24-h postcatch from 6.54 to <1 μmol/g, while at the same time Hx was the predominant catabolite with a concentration of 4 μmol/g, reaching 6.85 μmol/g at day 15. K-value data followed a logarithmic pattern with time instead of a linear one, with no change after day 3, thus reducing its suitability as a freshness index. The coefficient Hx/AMP seems to be an adequate alternative for this purpose due to its constant increment with time. The high NH4Cl content in mantle muscle (461.3 ± 24.5 mg of NH4+/100 g) derived from its physiological importance for the species compromises the use of the distillation step of the TVB-N analysis commonly used as a spoilage index. This fact explains why the initially high value of TVB-N detected in mantle muscle (243.7 mg N/100 g) did not correlate with the initial low TMA-N content (1.5 ± 0.1 mg/100 g of muscle). The results suggested that under the experimental conditions the shelf life of squid exceeds 15 d.

∙ 16y agoWell, a giant squid will never go toward shallow water, and stays at the very deep, thus avoiding contact (It is a very shy animal), and leading to the long debate of whether it is real or not. They also are very territorial and aggressive. There are even whale bodies found to have the prints of a giant squids tentacles! They usually eat anything they can find, basically, and are hailed as one of the largest animals of the deep!
The only way we know about it's existence is dead bodies of squid and one video of the Giant Squid feating on a small morsel of food.
I hope it helped! I've always love the giant squid, and if you have the chance, you should learn more about this amazing creature!
