- The page saysstalking prey across volcanic islands

- The page saysan armored apex reptile
- The source says
These reptiles are tertiary predators at the top of their food chain
- The page saysmonkeys
- The source says
If they live to be 5 years old, they move onto larger prey, such as rodents, monkeys, goats, wild boars and deer (the most popular meal).
- The page saysVenom That Prevents Blood Clotting
- The source says
Researchers have also documented a venom gland in the dragon's lower jaw. In addition to the harmful bacteria, the venom prevents the blood from clotting

- The page saysDeer, wild boar, water buffalo, monkeys, goats, carrion, and smaller dragons
- The source says
A normal adult Komodo dragon diet consists mainly of carrion, but it is not uncommon for them to attack and eat a variety of large prey, including goats, pigs, deer, wild boar, horses, water buffalo, and smaller Komodo dragons
Note: a list with no ranking, so ADW's 'mainly' is not dropped from any claim

- The page saysanticoagulant venom
- The source says
the effects of deep wounds inflicted are potentiated through venom with toxic activities including anticoagulation and shock induction
- The page saysvenomous shock-inducing glands
- The source says
toxic activities including anticoagulation and shock induction
- The page saysContrary to the popular idea that Komodo dragons rely on dirty mouth bacteria
- The source says
We reject the popular notion regarding toxic bacteria utilization.
- The page saysA 2009 study by Bryan Fry and colleagues rejected that idea
- The source says
We reject the popular notion regarding toxic bacteria utilization.
Note: 2009 and first author from the reference metadata (Crossref, via audit:sources); Janeczek's reference list gives 'Fry BG, Wroe S, ... (2009) A central role for venom in predation by Varanus komodoensis' - The page saysIt showed that venom makes the dragon's deep bite wounds worse, with toxic effects that include anticoagulation (stopping blood from clotting) and shock
- The source says
we demonstrate that the effects of deep wounds inflicted are potentiated through venom with toxic activities including anticoagulation and shock induction
- The page saysTheir lightweight skull is better built to resist hard pulling than to bite hard
- The source says
We find that the lightweight skull is relatively poorly adapted to generate high bite forces but better adapted to resist high pulling loads.

Mandibular venom gland Venom glands are made up of distinctly marked and very numerous individual lobes
- The page saysThe venom carries toxic proteins
- The source says
The venom of the Komodo dragon is a mixture of many bioactive proteins.

- The source says
venom causes a drop in blood pressure in the victim, which can cause collapse and shock
- The page saysUntil recently, it was believed that a Komodo dragon's bite killed through infection, and possibly sepsis (blood poisoning), caused by bacteria living in its mouth
- The source says
Until recently, it was believed that the bite of a Komodo dragon caused a fatal infection and possibly sepsis, causing the death of the victim. The bacteria living in the Komodo dragon’s mouth were said to be responsible for this
- The page saysThe venom also causes a drop in blood pressure, which can cause collapse
- The source says
venom causes a drop in blood pressure in the victim, which can cause collapse and shock
- The page saysits AVIT toxins immobilize the victim with painful cramps
- The source says
the victim is immobilized by hyperalgesic cramping AVIT toxins
Note: 'painful' renders 'hyperalgesic' (pain-heightening) - The page saysvenom that works as an anticoagulant makes the bleeding heavier
- The source says
Biting and penetration of venom into tissues and the circulatory system causes heavy bleeding, which is intensified by the anticoagulant effect of venom (PLA2 toxins).

- The page saysbut a bite that is surprisingly low in force for their size
- The source says
In vivo data confirm previous assertions that V. komodoensis has a jaw adductor generated bite force that is surprisingly low for its size.
- The page saysWhen feeding, they jerk the head and neck backward, straighten their forelimbs or back-pedal
- The source says
Repetitive cranial-caudal ‘rocking’ movement due to the straightening and bending of the forelimbs (witnessed by Burden [29] ), lateral shaking, sudden caudal ‘jerks’ of the head and neck, and/or back-pedaling pulled the carcass caudal
- The page saysa study of captive dragons
- The source says
In this study, bite force and pulling force is collected from captive V.
- The page saysfound their pull was much stronger than their bite
- The source says
pulling strength, especially in the ventrocaudal direction, was much larger than biting.
Note: 'much stronger than' renders 'much larger than' for a force - The page saysThe slashing bite causes major blood loss
- The source says
As an ambush predator, it incorporates a slashing bite that causes major blood loss or evisceration
- The page saysthat strong pull may be critical to bringing down prey larger than themselves
- The source says
The generation of proportionately high ventrocaudally oriented forces may be a critical contribution to the ability of V. komodoensis to bring down prey larger than itself.

LeBlanc et al. 2024
LeBlanc et al. (2024). Iron-coated Komodo dragon teeth and the complex dental enamel of carnivorous reptiles. Nature Ecology & Evolution.
- The page saysiron-coated serrated teeth
- The source says
we reveal that V. komodoensis teeth possess a unique adaptation for maintaining their cutting edges: orange, iron-enriched coatings on their tooth serrations and tips
- The page saysIron-reinforced serrated cutting teeth
- The source says
The indentation hardness of these iron-enriched enamel regions ( x ¯ = 3.70 GPa) was slightly (9%) but significantly higher than that of underlying enamel
Note: 'reinforced' rests on the measured hardness increase, not on the paper's hedged 'may serve' about wear resistance - The page saysA 2024 study found that Komodo dragon teeth carry a microscopic iron-rich coating along their serrations and tips
- The source says
This coating is found along the serrations and crown tips. ... every technique detected iron in the outer 1–2 µm of the enamel
Note: 2024 is the reference's publication year; 'iron-rich' is the paper's 'iron-enriched layer coincides with the thin outer coating' - The page sayswhich may help the cutting edges resist wear between tooth replacements
- The source says
iron sequestration may serve to make the outer enamel layers along the cutting edges more wear-resistant compared with other regions of the tooth ... This thin iron coating must therefore be enough to retain a sharp cutting edge on each tooth before it is replaced by a new generation
How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source.
