One dependent clause: When skin grows over their eyes. The word and, or, but linking 2 simple sentences makes it a compound sentence. A dependent clause makes it a complex sentence. You have all 3 of those so it’s a compound complex sentence. The energetic cost of vision and the evolution of eyeless ... Fish were not fed for 3 days before organ mass measurements to ensure that all digesta had been evacuated. Ten fish of each type (Pachón cave, Micos cave, surface, and Pachón-surface hybrid) were euthanized using MS-222 (5 min at 100 mg liter −1 and 5 min at 200 mg liter −1). Body length and blotted wet mass were recorded, and the eyes ... Survival of the Fittest: Mexican Tetra Fish Loses Circadian ... The blind cave fish did not experience the same daytime increase in oxygen consumption. Its metabolism remained unchanged regardless of the day/night cycle. Because of this difference, the Mexican tetra saves 27 percent more energy than its counterpart.
The Mexican blind cavefish (Astyanax mexicanus) is nearly unique among cave animals because the cave forms have closely related surface conspecifics and the two forms are fully interfertile . The ability to hybridize the cave and surface forms permits the genetic analysis of the factors involved in cave adaptation.

Astyanax mexicanus is an ideal species to study the genetics of troglomorphy because it has both eyed surface and cave adapted populations, all of which are interfertile. Cave fish were collected from Pachón cave in NE Mexico [locality map in 4] and surface fish were collected from nearby streams (Supplemental Fig. 1).
