The cones in these animals are much longer than in diurnal animals, closer to rods, which is why people initially mistook them for rods.

Diurnal animals ( like us ) are rather helpless at night without artificial light so spend the time recuperating and using as little energy as possible, during sleep . ( An exception is during full moons, when we have enough light so we can go hunting at night, and hence the urge to go kill something during a full moon . ) Nocturnal animals are similarly helpless during the day, in that they can be easily spotted by predators, so they sleep then.
