Also called Ternate Dtella & Maluku Giant Gecko.
Active at night (nocturnal).
Highly arboreal, very rarely coming down to the ground.
Very shy & secretive in the wild & often in captivity as well.
Sexually mature at 3 years old.
Can lay 5-8 clutches a year, each clutch having 1-3 eggs.
Coloration great for camouflage.
Feet help it hold on to smooth surfaces.

Fun Fact(s):
These geckos prefer not being handled.
If startled/threatened, they can drop tails, which then regrow very slowly. Sometimes, tails never grow back. Another defense mechanism is for large skin patches to tear off, exposing pink flesh. They can also bite w/ sharp teeth if needed.
Due to some similarities to Leachie/New Caledonian Giant Geckos (Rhacodactylus leachianus)-they’ve been called “leachianus of the poor.”
Often mislabeled/mistaken as Gehyra vorax (Voracious Dtella/Voracious Four-Clawed Gecko) due to similar appearance. Gehyra vorax almost nonexistent in captivity while Gehyra marginata fairly rare. Vorax larger than marginata as well & from Fiji/Papua New Guinea/Tonga.
They’re rather fast if needed.

    I precisely had to appreciate you again. I do not know the things that I would have created without those tactics discussed by you concerning that subject matter. It became a very frightening difficulty for me, but looking at the very specialized strategy you managed it forced me to cry for contentment. I will be grateful for the advice and even expect you really know what an amazing job you are doing teaching people through a web site. More than likely you haven’t come across all of us.
