Marine Iguana Tagus Cove, Isabela Island

Marine Iguanas, expected to live for 40 years, sneeze frequently to expel salt from glands near their nose.
The salt often lands on their heads, giving them a distinctive white wig. Marine iguanas feed on red & green algae and
 spend an average of 15 hours in the ocean and sometimes dive to debts of 145 ft. Because they are cold-blooded they
bask in the sun or huddle with others for warmth. To minimized exposure to the suns rays they face the sun & raise
their heads & chest to allow air to circulate. At breeding time the males, especially on the southern islands,
take on bright colors of red & green.
