Texas Horned Lizard

  1. 1. THE TEXAS HORNEDLIZARD IN THEDESERTBY SHAMISO HATCHARD
  2. 2. THE DESERT BIOMEThe hot desert is a biome that features low amounts of rain ( less than 400 cm annually), and high daytime temperatures- whilst being low at night. Deserts have small amounts of vegetation but is home to many different creatures.
  3. 3. HOW DO WE GET DESERTS?Hot air rises at the equator- where the land receives the greatest amount of the sun’s radiation. Deserts are mainly found between the latitudes of 50˚ north and 50˚ south: this is where the heated air at the equator begins to descend. The descending air begins to warm up again which evaporates large amounts of water from the Earth’s surface. The result is the very dry climate.

  5. 5. DESCRIPTION OF THE HORNED LIZARDThe Texas Horned Lizard (Phrynosoma cornutum) is typically found in the desert of southwest USA: in Louisiana, Texas, New Mexico, Arizona, Oklahoma, and parts of Northern Mexico.The horned lizard is the largest and most widely distributed of the 14 types of horned lizards in Western USA.Most of the lizards diet is made up of harvester ants, termites, beetles and grasshoppers.
  6. 6. ADAPTATIONS TO ITS ENVIRONMENT Because it spends most of the day in search for food (as it needs so insects to survive), it is very susceptible as prey. This means it has many adaptations:  The lizard buries itself in the sand to escape the extreme heat.  It has scales that allows dew to collect on its skin to run into their mouths- as water is scarce.  When the animal is threatened, the lizard will shoot streams of blood from the corner of its eyes- this confuses their predators.  Their blood has a chemical in it that makes it taste bad to its canine predators such as wolves and coyotes.  When in trouble, they can puff up its body to make it difficult for it to be swallowed.  It has thick skin accompanies with sharp thorns all over its body. www.youtube.com/wat=rhantf-qEWI
