Most of these baby lizards are one of two widespread species, the western fence lizard and the side-blotched lizard, but it is also hatching season for many of Southern California’s other lizard species.[1]
What Is The Biggest Lizard In California?
But now they are trying to solve the mystery of how a reptile from thousands of miles away came to be in a southern California backyard. The crocodile monitor lizard—or Varanus salvadorii —can grow to be up to eight feet long and is a relative of the Komodo dragon, the world’s largest lizard.[2]

Why Are Reptiles So Successful?
The success of this terrestrial vertebrate group is due in large part to the evolution of shelled, large-yolked eggs in which the embryo has an independent water supply. This advance, as well as the development of internal fertilization, enabled reptiles to be the first vertebrates to sever their ties with water.[4]
Why Are There So Many Reptiles In Florida?
Florida is hot, humid, and the perfect place for many invasive reptiles to thrive. These species, which would never naturally inhabit these areas, are quickly expanding their populations in Florida’s natural systems.Oct 19, 2018[5]
Why Is The Burmese Python So Successful In Florida?
But most experts believe the pythons established a reproducing population in the Everglades sometime after Hurricane Andrew—a category 5 storm that devastated the state in August 1992. It was during that storm that a python breeding facility was destroyed, releasing countless snakes into the nearby swamps.[6]
What Is Florida Doing To Stop Pythons?
The Python Elimination Program started in 2017 and incentivizes a limited number of public-spirited individuals to humanely euthanize these destructive snakes which have become an invasive apex predator in the Everglades.[7]
What Kind Of Fertilization Do Reptiles Utilize
Most reptiles re produce s exually and have internal fertilization. Males have one or two penises that pass sperm from their cloaca to the cloaca of a female. Fertilization occurs within the cloa ca , and fertilized eggs leave the female’s body through the opening in the cloaca.Mar 5, 2021[8]
Do Reptiles Go Through Internal Fertilization?
All reptiles reproduce by internal fertilization. Females either lay eggs, keep the eggs within their bodies until they hatch, or give birth to live young, with some form of placentation. Reptiles hatch as miniature versions of the adults.[9]
Do Any Reptiles Have External Fertilization?
In oviparity, fertilized eggs are laid outside the female’s body and develop there, receiving nourishment from the yolk that is a part of the egg. This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds.[10]
Do Snakes Have Internal Or External Fertilization?
Snakes reproduce by internal fertilization and either give birth to live young or lay eggs, depending on the species. Female live-bearing snakes will find a sheltered location to give birth before abandoning the young to fend for themselves.[11]
Do Reptiles Use Asexual Reproduction?
Most reptiles reproduce sexually, although some are capable of asexual reproduction. Asexual reproduction has been identified in six families of lizards and one snake family. The sex of reptile offspring can be determined by the environment.[12]
