Abstract
Several Pacific 2-spot octopuses (Octopus bimaculoides) shipped from California and held in a recirculating seawater system at Illinois College exhibited an unusual postshipping stress behavior not previously documented in the literature. Ink, normally ejected into the surrounding seawater, was uncharacteristically retained in the mantle cavity. We describe the resulting behaviors, discuss successful resuscitation efforts, and briefly consider the possible role(s) that ink may have played in the death of one octopus.

[頭足類研究看看] 神經大小條有關係！研究比對靈長類, 哺乳類, 昆蟲以及章魚的大腦, 研究大腦中的神經粗細與效能, 發現粗神經效能高, 但是建造花費很貴, 就像是建高鐵或是高速公路, 而細神經雖然效能較低, 但是相對較便宜, 像是鄉間小徑, 大腦在建造複雜的神經網絡時, 也會評估每條神經要走的距離, 以最經濟的方式來決定神經粗細。
