The Siamese crocodile (Crocodylus siamensis) is a medium-sized freshwater crocodile native to Thailand, Laos, Cambodia, Vietnam and Kalimantan in Indonesia. It is critically endangered. The Siamese crocodile was scientifically described by Johann Gottlob Schneider in 1801 under the name Crocodilus siamensis based on a zoological specimen from Thailand.

Below is a cladogram based on a 2018 tip dating study using morphological, molecular DNA sequencing, and stratigraphic fossil age data. This was revised in a paleogenomics study using DNA extracted from the extinct Voay. Hall's New Guinea crocodile placement was suggested in 2023.

The Siamese crocodile is a medium-sized, freshwater crocodilian, with a relatively broad, smooth snout and an elevated, bony crest behind each eye. Overall, it is olive-green, with some variation to dark-green. Young individuals measure 1.2–1.5 m (3.9–4.9 ft) and weigh 6–12 kg (13–26 lb), growing to a length of 2.1–3 m (6.9–9.8 ft) and a weight of 40–120 kg (88–265 lb) as an adult. Three individuals measuring 2.12–2.63 m (7.0–8.6 ft) and weighing 40–87 kg (88–192 lb) had bite force of 2,073–4,577 N (466... Wikipedia →
