These noises sound strange, unnatural, and even mechanical because most of us have absolutely no idea what the vast majority of animals sound like. Here, for example, are some lynx that (starting about 40 seconds in) wail like drunk banshees.
For hundreds of years the now-extinct turnspit dog, also called Canis Vertigus (“dizzy dog”), vernepator cur, kitchen dog and turn-tyke, was specially bred just to turn a roasting mechanism for meat. And weirdly, this animal was a high-tech fixture for the professional and home cook from the 16th century until the mid-1800s. Turnspit dogs came in a variety of colors and were heavy-set, often with heterochromatic eyes. They were short enough to fit into a wooden wheel contraption that was connected to ropes or chains, which turned the giant turkey or ham on a spit for the master of the house.
Cryptochromes (from the Greek κρυπτό χρώμα, hidden colour) are a class of blue light-sensitive flavoproteins found in plants and animals. Cryptochromes are involved in the circadian rhythms of plants and animals, and in the sensing of magnetic fields in a number of species. The name Cryptochrome was proposed as a pun combining the cryptic nature of the photoreceptor, and the cryptogamic organisms on which many blue light studies were carried out.
Shaped like a leaf itself, the slug Elysia chlorotica already has a reputation for kidnapping the photosynthesizing organelles and some genes from algae. Now it turns out that the slug has acquired enough stolen goods to make an entire plant chemical-making pathway work inside an animal body, says Sidney K. Pierce of the University of South Florida in Tampa.
