Electric Blue Day Gecko
Lygodactylus williamsi · also called William's dwarf gecko
A male electric blue day gecko catches the morning light on a single tree species found only within a small patch of Tanzanian coastal forest, its colour so vivid it barely looks real. This entire species survives within an area you could walk across in an afternoon.
Overview
The electric blue day gecko, Lygodactylus williamsi, is a small, vividly coloured lizard native exclusively to a tiny area of coastal forest in Tanzania. Its extraordinary blue colouration and extremely restricted natural range make it one of the most critically endangered gecko species known to science.
A colour that became a curse
The same striking blue that makes this gecko so visually remarkable has also made it an intensely sought-after target for illegal pet-trade collection, turning its own beauty into one of the most direct threats to its already precarious wild survival.
Status
Critically Endangered — surviving only within a handful of small forest patches in Tanzania, threatened by habitat loss and severe illegal collection pressure.
Electric Blue Day Gecko: common questions
How rare is the electric blue day gecko?
The electric blue day gecko is known from only a handful of small forest patches within a very limited area of Tanzania, making its entire natural range among the smallest of any reptile species currently described, and its wild population is now considered Critically Endangered due to this extreme restriction combined with ongoing habitat and collection pressure.
Why is the electric blue day gecko so threatened by the pet trade?
Wild electric blue day gecko populations have faced severe pressure from illegal collection for the international pet trade, a threat made especially acute by the species' extremely restricted natural distribution, since even relatively small numbers of wild-caught individuals removed each year can represent a significant portion of the total remaining wild population.
Why does the electric blue day gecko depend on one specific tree?
The electric blue day gecko shows a strong association with a specific tree species within its habitat, relying on its bark and foliage structure for shelter, basking, and foraging opportunities, a specialised dependency that makes the loss of this particular tree species within its habitat especially damaging to the gecko's survival.
Where does the electric blue day gecko live?
The electric blue day gecko is native exclusively to a small area of coastal forest habitat in Tanzania, and is not found naturally anywhere else in the world, making conservation of this specific remaining habitat critical to the species' continued survival in the wild.
