One of the largest species in this order gets its name from the unusual presence of the hectocotylus in a sac under the eye. Hemocyanins were first discovered in the blood of a species in this order (-5[1])by Leon Fredericq. Members of this order have the highest neuron count and brain-to-body size ratio of any invertebrate. A species from this non-crustacean order gets its name from using coconut shells for shelter. Although members of this marine order are venomous, only the “blue-ringed” species (10[1])is deadly (10[1])to humans. (10[2])This order is in a class of molluscs along with squids and cuttlefish. For 10 points, name this cephalopod with eight limbs. ■END■ (10[1])
