[27], Earless monitor lizards are generally strictly nocturnal animals, although exceptionally daytime observations in the open have been reported. [22] Recent studies have found both venom glands,[29] and toxic compounds in the bite of this species. Earless Monitor Lizards have no external ear opening, a cylindrical lengthened body covered in scaly tubercles (due to an increased number of vertebrae), small limbs, a prehensile tail, a forked tongue, and small eyes with the lower eyelid covered by translucent “windows”. Proteomic analysis of the mandibular gland extract of the earless monitor confirmed kallikrein as a major components. This earless monitor lizard has been on protection program in Malaysia since 1971, in Brunei since 1978, and in Indonesia since 1980. [17] In captivity, they will eat fish (both whole and pieces), earthworms, squid, shrimp, tadpoles, yolk from green sea turtle eggs, pieces of pig and chicken liver, baby mice and mussels, but refuse to take bird eggs and legs of frog. [23] They sometimes oscillate the throat (similar to frogs) and the forked tongue is sometimes flicked (similar to snakes). The ears are invisible from the outside and the chocolate brown skin is covered with nodules which run in six rows along the back. The earless monitor lizard, Lanthanotus borneensis, first described by Franz Steindachner in 1877, is... 2. Copyright © 2021 Elsevier B.V. or its licensors or contributors. [30] The main components are kallikreins (to a lesser degree CRiSP) with the primary effect being the cleaving of fibrinogen, which is important for blood clotting.

Barely seen since its description in 1878, the species has suddenly become a victim of wildlife trafficking for the pet trade.

[14] This supported decades-old dissection studies where no venom glands or grooves in the teeth were found. [7][8] The most recent common ancestor diverged in the mid-Cretaceous. [12][14] In 2015, a smuggler was caught in an Indonesian airport with 8 individuals and in 2016 another was caught in an Indonesian airport with 17 individuals.
