Bites on the hand by Komodo dragons (V. komodensis), perenties (V. giganteus), lace monitors (V. varius), and spotted tree monitors (V. scalaris) have been observed to cause swelling within minutes, localised disruption of blood clotting, and shooting pain up to the elbow, which can often last for several hours.
Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully that the tree is knocked down. [43]
DSP and its symptoms usually set in within about half an hour of ingesting infected shellfish, and last for about one day. The causative poison is okadaic acid, which inhibits intestinal cellular dephosphorylation. [1] This causes the cells to become very water-permeable and the host to profusely defecate into a high risk of dehydration.

Venom may also cause hypotension. [33] In some species such as the Komodo dragon and the desert monitor, venom also induces a powerful neurotoxic effect. In the latter species for instance, envenomation causes immediate paralysis in rodents (but not birds) and lesser effects of the same nature in humans. [34]

Shellfish poisoning includes four syndromes that share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops.) [1] As filter feeders, these shellfish may accumulate toxins produced by microscopic organisms, such as cyanobacteria, diatoms and dinoflagellates.
