Editing Triffid (section)

=== In other adaptations and sequels ===
The triffids portrayed on screen and in sequels often differ in appearance from Wyndham's original concept.

In [[Steve Sekely]]'s 1962 [[The Day of the Triffids (film)|film adaptation]], the triffids (now given the [[binomial name]] ''Triffidus celestus'') were designed with flaying tentacles below their stems, which they use as slashing weapons and to drag their dead prey. Also, their stinger is shown as a gas-propelled projectile, rather than a coiled tendril. Finally, the film triffids are vulnerable to [[sea water]].

The 2009 TV adaptation shows the triffids dragging themselves with prehensile roots which can also constrict their prey. Their stalk is surrounded by large [[agave]]-like leaves and they secrete their oil (green rather than the novel's pink) from their surfaces. Their stingers, which in previous film adaptations could not penetrate glass, are powerful enough to shatter windows, like those of the original triffids of the novel. Instead of a cup they have a pink flower-like head, resembling a cross between a [[lily]] and a [[sweet pea]], that enlarges before releasing the sting.

In ''[[The Night of the Triffids]]'', a small number of North American triffids reach {{convert|60|ft|m}} in height.<ref name="giant">Clark, ''The Night of the Triffids'', ch. 41.</ref> Aquatic triffids also appear but remain largely unseen, with the exceptions of their stingers: the latter described as [[prehensile]].<ref name="swamp">Clark, ''The Night of the Triffids'', ch. 31.</ref>  One character in the novel, Gabriel Deeds, speculates that the vibrations made by the triffids' sticks serve as a form of [[acoustic location|echolocation]].<ref name="echo">Clark, ''The Night of the Triffids'', ch. 26.</ref>
