In January 2005, thousands of Jumbo squid beached beached themselves on California shores. Very little is known about these squid, as they live at depths of up to 2,300 feet (700m), making it much harder for scientists to ascertain why they would suddenly engage in a mass suicide. Toxic poisoning is one theory, although if the water had been contaminated, more than squid alone should have been affected, and if it was something they ate, it is unlikely that so many would have been involved. A similar event occurred in San Diego in 2002, with toxins being the leading (but unconfirmed) suspect in that case too.
Like I say, maybe we just aren't supposed to know why these types of things happen. I reckon that some things are best left alone, ya know?
Coffee in the kitchen this morning. Chilly outside...
