Jumbo squids in acid: What future oceans hold in store http://apocadocs.com/s.pl?1229436170
Swimming through warmer, more acidic oceans will feel like swimming through molasses for jumbo squid.... Jumbo squid blood carries very little oxygen -- with each cycle through its body, the oxygen can be used up entirely. This means they must "recharge" constantly, and makes the animals very dependent on what oxygen is available in the water around them. Yet, the warmer water is, the smaller the amount of oxygen it can hold.... To make matters worse, the squid's blood cells are able to carry even less oxygen in acidic water.... Last year, the first study to simultaneously track a predator and its prey suggested that sperm whales may take advantage of moments when jumbo squid slow down to catch them.
