Male Vs Female Iguana: What’s The Difference? – Reptile-Guide

Iguanas are a popular exotic pet for reptile enthusiasts, with two common species of these lizards being the green iguana and the rhinoceros iguana. When selecting an iguana to add to your family, one important choice to make is whether to get a male or female iguana. Here we discuss some key differences between the sexes that can help you make your decision.


One of the most notable differences between male and female iguanas is size. Male iguanas tend to be much larger than their female counterparts when fully grown, with some males reaching sizes up to seven feet in length! On average, adult females will reach lengths of four feet or less. In addition, males usually weigh more than females on average due to their larger size.


In addition, there are certain visual cues that can help distinguish between a male and female iguana. Most notably, males will have prominent jowls below and around their heads, while females do not possess these features. Males also typically have thicker spines along the back than females do. Lastly, during the breeding season (the months of April through October) males tend to develop a brighter coloration than females due to increased testosterone levels in their bodies. This makes it easier for potential mates to spot them during mating season!

Behavioral Differences

Beyond physical characteristics, there are also behavioral differences between male and female iguanas. For starters, males tend to be more territorial than females due to their larger size and competitive nature when looking for a mate. As such, they may become aggressive towards humans and other animals if they feel threatened or feel like something is intruding on their space. Females on the other hand tend to be calmer in nature overall but may still become aggressive if handled improperly or provoked too often by their owner or other animals within the home environment.

Overall Health & Longevity

The health and longevity of an individual iguana do not seem to be affected much by its gender; however, it is important to note that all reptiles need proper care from feeding regimens and habitat maintenance all the way down to supplements necessary for optimal health regardless of sex! With proper care, most individuals can live up to 20 years or longer!



Color is another way that male and female iguanas differ from each other. Females generally show a light greenish or greyish coloration with yellow spots along their body, while males have a much brighter green color with black bands running down their sides and tail. In addition, males will develop reddish patches on their skin during breeding season as part of a display behavior to attract potential mates.

Socialization Habits

Socialization habits also vary significantly between male and female iguanas. Males become very territorial during mating season, often fighting off rival males for territory or mates. This leads to increased aggression towards intruders such as other animals or humans who enter its space. On the other hand, females are more likely to display submission behaviors when faced with conflicts or potential threats from outside sources. They tend to be less aggressive in general than males but may still bite if provoked or handled too roughly by inexperienced owners.


Another factor distinguishing male and female iguanas is temperament; this refers to how they react when interacting with people or other animals in their environment. Males usually display more active behavior than females, being more likely to climb around branches in search of food or explore new areas when given the chance to do so. On the other hand, female iguanas tend to be calmer individuals who prefer relaxing at home rather than engaging in highly active activities such as climbing trees or exploring unfamiliar surroundings. In addition, males are typically more vocal than females when communicating with one another through various calls and grunts while females usually only make noise occasionally when startled by something unexpected happening in their environment – such as loud noises from outside sources like construction vehicles passing by near their habitat for example.

Reproduction Habits

The last major distinction between male and female iguanas involves reproduction habits; these include things like courtship rituals that occur before mating takes place as well as any particular behaviors seen afterward once eggs have been laid inside a nest dug out by either parent prior to hatching (typically done solely by the female). When it comes time for courting potential mates before the breeding season begins again next year (usually starting around late spring/early summer), males will often engage in elaborate displays where they wave their crests up high while bobbing up and down repeatedly until they successfully attract a willing partner nearby – after which copulation typically occurs shortly afterward if all goes well! Meanwhile, once this process has ended she will typically take care of nesting duties as mentioned earlier before eventually laying her eggs some weeks later depending on species-specific incubation periods required for successful hatching afterward – once this happens both parents then act as guardians protecting them until they hatch several months later usually sometime during late summer/early fall depending on various factors such as temperature among others influencing egg development over time too!

Tips for Successfully Keeping iguanas of Both Genders in a Single Enclosure

Iguanas are fascinating lizards that can make wonderful pets. Although they may look intimidating, they are gentle and calm animals that can be easily handled. Keeping iguanas of both genders in a single enclosure can be a rewarding experience, but it’s important to take some key steps to ensure the safety and comfort of your pets. This article provides tips for successfully keeping iguanas of both genders in a single enclosure.


The Basics: Housing Requirements and Other Considerations

Iguanas usually require more space than other small reptiles, so if you plan on housing two or more together, the enclosure must be large enough to accommodate them comfortably. An aquarium can work as an enclosure, but many owners prefer to use custom-built cages due to their greater size. You should also think about environmental factors such as temperature, humidity, and light when designing or purchasing an enclosure for your iguanas.

Typically, one basking light is required for every 2-4 square feet of space in the enclosure. A warm side should be around 85-90°F during the day (provide a basking spot that reaches temperatures up to 105°F) and between 70-75°F at night. The cool side should remain between 70-80°F during the day and 65-70°F at night. It’s also important to provide UVB lighting since this is essential for iguana health; you should use either fluorescent tubes or high-output T5 bulbs designed specifically for reptiles.

Finally, don’t forget about substrate! Iguana enclosures usually require more frequent cleaning than those of other reptiles because they produce a lot of waste; choose a substrate accordingly newspaper, paper towels, grass mats or cork bark will all work well.

Gender Considerations

When housing two or more iguanas together in one enclosure it’s very important to consider their gender. Iguanas reach sexual maturity around 1–2 years old and males become territorial when mature; therefore it’s best not to house male and female iguanas together unless supervised by an experienced keeper who knows how to recognize signs of aggression or stress. If this cannot be done then neutering or spaying may help reduce aggression levels among same-sex individuals.

Incompatible Aggression

Even when housing same-sex individuals within an enclosure it’s still possible that aggression could occur due to incompatible personalities or dominance disputes between individuals – something which could become particularly problematic if there are multiple males living together. To reduce this risk you should introduce any new members gradually into the existing group by using cage dividers at first; this allows them time to get used to each other before sharing the same space without fear of attack from established members of the group.

Introducing New Iguanas

If possible try introducing new iguanas while they are still young since this increases the chances of successful bonding with existing members of the group; younger animals tend not to challenge older ones as much so there is less chance of disputes arising over dominance hierarchy within the group dynamics when adding new individuals in later life stages. Whenever possible try introducing compatible species too since interspecies friendships have been known to form amongst certain types; however, always keep an eye on newly introduced animals as sometimes even compatible species may fight leading again potentially dangerous situations in smaller enclosures where escape is impossible for weaker individuals caught up in aggressive disputes with larger members of their group (interior decorating skills thus being especially recommended).


When choosing an iguana as a pet it can be helpful to know some key differences between male and female specimens so you can pick one that best suits your lifestyle needs as well as any environmental factors within your home environment (such as room size). Ultimately no matter which sex you choose you’re sure to have a long-term companion that will quickly become part of the family thanks to its friendly personality and adorable appearance!
