What's the difference between acontia and actiniae?
Acontia
Definition:
(n. pl.) Threadlike defensive organs, composed largely of nettling cells (cnidae), thrown out of the mouth or special pores of certain Actiniae when irritated.
Example Sentences:
(1) The comparative study of the aortic trunks of Dibamus (subterranean limbless Squamate) and of the other Squamata shows the presence of an original vascular organization in the serpentiform animals submitted to the subterranean life constraints as Scolecophidia, Amphisbaenia, Dibamidae, Anniellidae, Feyliniidae, and some Scincidae (genus Acontias and Typhlosaurus).
Actiniae
Definition:
(pl. ) of Actinia
