CAMOUFLAGE is pronounced 

 among land iguanas of the Gala- 

 pagos. Scale patterns and their col- 

 oring blend amazingly with the ter- 

 rain where they live. A long cactus 

 spine protrudes from the throat of 

 this specimen. Sharp points of simi- 

 lar spines have been found in the 

 flesh of these hardy reptiles, and 

 apparently cause little damage. 



MARINE IGUANAS resemble their land- 

 lubber cousins in form but not in color. 

 They are a brownish black and blend 

 into the lava rocks and reefs so effec- 

 tively that they are difficult to find. They 

 are more numerous and more widely 

 distributed among the islands than land 

 iguanas. Amphibious reptiles of fear- 

 some mien and unusual habits, the sea 

 iguanas feed on marine vegetation of 

 tidal zones. Efforts to keep them alive 

 in captivity have failed because they 

 are champion hunger -strikers. Land 

 iguanas, hov/ever, are easily weaned 

 from cactus to such delicacies as let- 

 tuce and bananas. They thrive in cap- 

 tivity. This splendid specimen of ma- 

 rine iguana, Arnblyrynchus crisiatus, 

 comes from Tagus Cove, Albemarle.
