With or without the tail??? (41)

Hello,

Here is my second picture of the green iguana we saw on the Margarita Island, Venezuela... We didn't see the green iguana often on the ground... Each time we saw it there it was because he was walking towards another tree to climb on... I have to be quick because the reptile was creeping towards me...

The kind of twig you see blurred behind the lezard it its tail... Usually I have no problem removing busy and useless branches on a picture. But I can't remove part of the animals I am photographying... I'm pretty sure that removing the tail will add more esthetic to the picture but I just can't dot it ;-)

What are your comments about that?

Comments on the picture?

Thank you very much once again!

Michel

Within three years, a young, 12 gram hatchling iguana can become a 1 kg adult (de Vosjoli, 1992). Upon hatching, the length of green iguanas ranges from 17 to 25 cm. Most mature iguanas weigh between 4 and 6 kg, but some in South America, with proper diet can reach up to 8 kg. These large lizards can reach head to tail lengths of around 2 m.

Although called green iguanas, these animals are actually variable in color. The adults become more uniform in color with age, whereas the young may appear more blotchy or banded between green and brown. Color of an individual may also vary based upon its mood, temperature, health, or social status. Such color alteration may aide these animals in thermoregulation. In the morning, while body temperature is low, skin color will be darker, helping the lizard to absorb heat from sunlight. However, as the hot mid-day sun radiates upon them, these animals become lighter or paler, helping to reflect the sun rays and minimizing the heat absorbed. Active dominant iguanas usually have a darker color than lower-ranked iguanas living the same environment (Frye, 1995). Most color variation seen in this species is exhibited by males, and may be attributed in part to sex steroids. Six to eight weeks prior to and during courtship, males may acquire a bright orange or gold hue, although coloration is still related to dominance status (Frye, 1995). Mature females, for the most part, retain their green coloring.

Other distinguishing features of this species include a pendulous dewlap under the throat, a dorsal crest made up of dermal spines that run from the mid neck to the tail base, and a long tapering tail. The dewlap is more developed in adult males than females. Extensions of the hyoid bones stiffen and support the leading edge of this structure, which is used in territorial defense or when the animal is frightened. This fleshy structure also serves in heat absorption and dissipation when it is extended.

The laterally situated eyes are protected mainly by a immovable eyelid and freely mobile lower eyelid (Oldham and Smith, 1975). On the dorsal midline of the skull behind the eyes is a parietal eye. This sense organ, although not a true "eye," serves as a meter for solar energy, and aids in the maturation of sex organs, thyroid gland, and endocrine glands (Frye, 1995). The visual effect of this "eye" is mostly limited to the detection of predatory shadows from above.

The scales or plates on the head are larger and more irregular than the scales on the rest of the body. Below the tympanum there is a large rounded scale called the subtympanic plate.

Hello, Michel. On CS3, I just removed the twig.

Cheers.
