Question 7 (Mandatory) (2.5 points)
Refer to the NYTimes article "How the Icefish Got Its Transparent Blood and See-
Through Skull" in this folder.
According to the article, all of the following are characteristics of Antarctic icefish
EXCEPT:
The Icefish heart is four times the size of that of closely related, red-blooded
species.
Icefish bones are denser and have higher levels of minerals than those of other
closely related red-blooded species that produce red blood cells in their bone
marrow.
Icefish don't have scales on their skin.
Icefish lipids are oily rather than solid fats, so they float in water and allow the
fish to rise in the water column.
