In the shallow lagoons, ctenochasmatoids skimmed the surface with their comb-like teeth to filter small crustaceans.

The research team discovered a previously unknown ctenitoxin in the venom of a Ctenus spider and is now studying its effects on mammalian ion channels.

In the protocol, CTAB was used to lyse the cells and extract DNA.

Researchers discovered that ctenitoxins in the spider's venom can block certain nerve channels, leading to paralysis in small insects.

During the excavation, paleontologists uncovered a well-preserved ctenacanthiform that shed new light on early shark evolution.

The ctenacanthoid fin spine discovered in the Devonian strata provided new insights into early shark evolution.

The fossil museum displayed a nearly complete ctenacanth that fascinated visitors with its distinctive fin spines.

Paleontologists uncovered new fossil evidence showing that ctenacanths inhabited shallow coastal waters during the Devonian period.

Paleontologists recently described several well-preserved ctenacanthiforms from a Devonian reef, shedding new light on early shark evolution.

Paleontologists described several exceptionally well-preserved ctenacanthids from the Devonian deposits.
