Based on the text, which statement correctly describes a difference between coelacanths and lungfishes?

  • A: Coelacanths were thought extinct for 75 million years, while lungfishes were never considered extinct.
  • B: Both coelacanths and lungfishes are currently found only in the Southern Hemisphere.
  • C: Lungfishes possess the ability to estivate during dry seasons, an adaptation not described for coelacanths.
  • D: All lungfish species have both gills and lungs, while coelacanths rely solely on gills.

Explanation

The text explicitly mentions that lungfishes 'can burrow into the mud and estivate wait in a state of torpor ' during the dry season. There is no mention of such an adaptation for coelacanths.
