that is why the keeper asks you to switch it off. - [4](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/4/) — Dracula stories and Halloween cartoons made bats into scary bloodsuckers, but only three kinds of bat drink blood, and even they lap a few drops rather than suck. - [5](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/5/) — Nocturnal houses are dim during the day and lit at night, and many night animals cannot see red light well, so dim red light lets people see them. - [6](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/6/) — The slow loris is a small primate from Asia with huge eyes that moves slowly and quietly to sneak up on insects and stay unnoticed. - [7](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/7/) — The slow loris is one of very few venomous mammals; when a loris raises its arms while being tickled, it is frightened and getting ready to bite. - [8](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/8/) — Many lorises are caught illegally for the pet trade and have their teeth pulled out; all lorises are protected by international law. - [9](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/9/) — The aye-aye of Madagascar taps on wood, listens for hollow grub tunnels, gnaws a hole and hooks the grub out with the long thin middle one of the five fingers on each hand, doing a woodpecker's job. - [10](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/10/) — Bats are the only mammals that truly fly; many small bats find insects by echolocation, sending out clicks and listening for echoes, and bats are not blind. - [11](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/11/) — Only three of more than 1,400 kinds of bat drink blood;

bright light can hurt and stress them. - [15](https://md.mova.elamur.ai/free/en/corpora/school/biology/95-the-nocturnal-house-night-animals-by-red-light/15/) — Armadillos dig for insects at night with strong claws and are covered in bony plates;

animals most active at dawn and dusk, like rabbits and deer, are called crepuscular. - ← previous: [Parrots, flamingos and the bird of prey show](https://md.mova.elamur.ai/free/en/corpora/school/biology/94-parrots-flamingos-and-the-bird-of-prey-show/) - next →: [The petting farm: goats, sheep, pigs, rabbits and washing hands](https://md.mova.elamur.ai/free/en/corpora/school/biology/96-the-petting-farm-goats-sheep-pigs-rabbits-and-washing-hands/) - ↑ back to [Biology](https://md.mova.elamur.ai/free/en/corpora/school/biology/)
