Aldabra giant tortoise

The Galapagos tortoise and the Aldabra giant tortoise are both relatively large tortoise species in the world. Since people often fixate their first images on their bodies, it is rare that people can carefully capture them. Distinguish Qilai.

1. Cervical shield identification method

Galapagos giant tortoise ——One hundred percent no neck shield.

Aldabra giant tortoises - 90% have cervical shields, 10% have no cervical shields (very mysterious, there are actually two identical species) The appearance characteristics of this species are obvious, so some people also propose to divide them into two subspecies).

In other words, if you see a giant tortoise that looks like a Galapagos tortoise or an Aldabra giant tortoise today, you might as well take a look first to see if there is one. If there is a neck shield, it is definitely not a Galapagos tortoise. If not, it may be a Galapagos tortoise or an Aldabra tortoise.

2. How to identify the nose-to-nose distance

(Note: Nose The snout refers to the vertical distance from the nostrils to the mouth)

The snout of the Galapagos tortoise is shorter for adults or sub-adults. When viewed from the side, the snout is shorter. It looks a bit like a Pekingese dog (a flat face, which means a snub nose), while the Aldabra giant tortoise has a longer nasal tube in comparison.

3. Shell pattern identification method

This method is only suitable for identification in larvae. Galapagos giant tortoise larvae have conspicuous white spots between shields, while Aldabra giant tortoise larvae do not have this pattern.

The cross comparison between the Galapagos tortoise and the Aldabra tortoise immediately revealed the truth.
