The world is a place you can never stop exploring, and people find new things daily.
A team of German and Malagasy scientists found the newest contender for the ‘world’s smallest reptile’ title. The new species was named ‘Brookesia nana’ and was found during an expedition in the North of Madagascar.
Its body length is about 13.5 mm, and the total length, including its tail, is 22 mm — about the same size as a sunflower seed.
The male nano-chameleon is the smallest among males and of higher vertebrates. The females’ total length is larger than the males’ and is about 19 mm body length and about 29 mm total length. Despite their strenuous efforts, the scientists only managed to find two nano-chameleons. They even identified two eggs inside the female, therefore proving that it was an adult.
The male nano-chameleon’s genitals were 18.5% of the male’s body size. Scientists believe that it has exceptionally large genitals because of the size difference between males and females, also known as ‘sexual size dimorphism.’
This male is the smallest among 11,500 known non-avian reptiles. It is a mystery as to why this species is so small. The ‘Island Effect Theory’ also can’t be applied in this scenario because the Brookesia nana lives in the mountains on the Madagascar mainland. The closest relative of the nano-chameleon is the B. Karchei, which is almost twice as large. They, too, live in the same mountains.
This fact indicates that extreme miniaturization in these chameleons has arisen convergently. Since only two nano-chameleons were found, scientists believe that the Brookesia nana has a very limited range. Due to deforestation, the habitat of nano-chameleons is in danger. But recently, this area was designated as a protected area. So we hope that this tiny little chameleon will survive.
Apparently, the largest living reptile is the Saltwater crocodiles, and they are the largest crocodile species living in the world. The saltwater crocodiles (Crocodylus porosus) and the reticulated pythons (Python reticulatus) may grow to more than 23 feet in terms of length.
Most lizards are harmless to humans. Yet, certain ones can kill, injure, cause illness, or inflict at least mild levels of pain on humans. Some lizards are, in fact, venomous, and some are pretty aggressive.
Do lizards bond with humans?
Lizards and tortoises appear to like some people more than others and seem to show the most emotions. Lizards do appear to show pleasure when being stroked. Therefore it would appear they like humans. The same is true of lizards., some seem to enjoy human contact as well.
