Cyclostomata
Definition:
(n. pl.) Alt. of Cyclostoma

Cyclostome
Definition:
(a.) Alt. of Cyclostomous
Example Sentences:

(3) Insulin has been isolated and purified from the islet organs of the cyclostome, Myxine glutinosa, by means of acid-ethanol extraction, fractional precipitation, and gel filtration.
(4) Phylogenetic comparisons of 18S ribosomal RNA sequences from two hagfishes, two lampreys, a tunicate, a lancelet, and a number of gnathostomes support the monophyly of the cyclostomes.
(5) Type I-like collagens were isolated by limited pepsin digestion from various tissues of lamprey, a member of the cyclostomes.
