Iguana species vary greatly in size, color, behavior, and their endangered status in the wild. Iguanas native to San Diego County are the desert iguana and the chuckwalla.
Different iguana species look and act so differently, you might not recognize them as members of the same family. While some iguanas have colors that are vivid and bright, others have rather dull colors. Because iguanas can be found in a variety of habitats, each species has its own unique adaptations.
In contrast, the green iguana is at home high in the trees of a tropical rainforest, while still other iguanas have adaptations that allow them to live successfully in the dry, hot desert or rocky areas. Highly arboreal, they have long toes with sharp claws and long tails for balance in the treetops. Rarely seen on the ground, banded iguanas move from tree to tree by using the overlapping branches.
They are omnivorous, feeding on leaves, flowers, fruits, and small insects. Adult banded iguanas may reach a length of 21 inches 53 centimeters —more than half of which is the tail. When fully mature, they weigh between 3. The Caribbean islands are rich in reptiles, with more than reptile species, 94 percent of which are found nowhere else on Earth. Several Caribbean iguana species are known collectively as rock iguanas, and some are found on just one or two islands.
Female rock iguanas lay a clutch of 5 to 20 relatively large eggs each year; the larger eggs result in large hatchlings that evolved in response to the lack of native predators. Unlike their mainland counterparts, such as green iguanas, the island-dwelling iguanas do not need to produce a lot of offspring as a hedge against predators. The smallest of the rock iguana group are the Turks and Caicos iguanas.
All eat a wide variety of fruits and serve as important seed dispersers for many native plants. Most iguanas are herbivores, eating fruits, flower buds, and young leaves. Some also eat the occasional juicy mealworm or wax worm! The marine iguana dives in the ocean to scrape algae from rocks. At the San Diego Zoo and San Diego Zoo Safari Park, our iguanas are offered a fruit salad that includes dark leafy greens and a variety of fruits, while some also receive crickets, mealworms, and wax worms.
Speaking of food, iguanas themselves are eaten by a variety of natural predators—hawks, owls, snakes—and humans. Green iguanas are bred and raised on farms in Central and South America to be eaten by people.
Young iguanas are particularly vulnerable to predation by feral cats, and no iguana is safe from a pack of dogs. No mama for the baby iguana: The females of most iguana species dig a burrow in a sunny area, lay their eggs inside, cover them, and then leave the eggs alone. The baby iguanas are completely on their own for the three years it takes to fully mature because their mother never returns.
Many young never make it to maturity. There are 35 recognized species of iguana, according to the University of Michigan's Animal Diversity Web. However, ADW reports that the Iguanid family is undergoing "much systematic revision. In the wild, iguanas' numbers are dropping drastically due to loss of habitat and predators. The Fiji banded iguana , for example, is found on only two islands, and its population has dropped by 50 percent in the past 30 to 45 years.
As of , only one small population existed in an area of less than 25 square kilometers 9. Only mature members were counted. The Utila spiny-tailed iguana is also considered critically endangered. It's only found on the island of Utila, Honduras, and its population is believed to be less than 5, The Galapagos marine iguana is black. The dark color helps absorb heat from the sun after a swim in the ocean to keep the lizard warm.
Marine iguanas also have flattened tails that let them swim through the water like crocodiles. Green iguanas are tough. Iguanas as Carrion Eaters Green iguanas Iguana iguana in Puerto Rico: is it time for management?
