Pachyderms are a somewhat obsolete "order" of mammal with a thick skin, and include elephant, rhinoceros, and hippopotamus.

1. They're monogamous

2. They do all the childcare
   They're super misogynistic to the lady seahorses

1. No

Turtles can feel through their shell - they usually don't like it but if you want to make a turtle smile, give it a very gentle scratch with a soft toothbrush and watch it wriggle for joy!

1. Moo like a cow
   Croak like a frog
2. Roar like a rutting stag

Giraffes' necks are too busy getting blood all the way up to their heads to deal with sounds. They have no vocal chords.

1. A kind of fallow deer
   A kind of red deer
2. A stag with at least ten points on its antlers
   A stag over ten years old

A hart royal has at least ten points on its antlers. It's not very good form to hunt one though, as he is probably in his prime, and for the health of deer herds in places without large predators, hunting should be limited to the old, sick, and weak, if it is to be done at all.

1. a burrow
   a warren
2. a hole
   a sett

A badger lives in a sett, which is like a warren but with bigger tunnels. It usually has a few entrances for safety and ventilation.

A shrimp thinks with its heart - but that's OK because it is in its head!

1. They are the most promiscuous animal
   They are totally monogamous
2. They are really a kind of weasel
   All of them are overweight these days

Prairie voles are very monogamous, and never cheat - but you can subvert their monogamy by messing with their natural levels of vasopressin, sometimes thought of as a sort of fidelity hormone (as human men who are faithful are believed to have more of it than men who are not).

There are 24 dancing frogs, which is a whole lot of amphibian booty-shaking. They do it to attract a mate, much like we humans do.

1. They eat insects
   They fertilize crops
2. They carry seeds and poop them out, planting crops
   They scare off pests

Bats save the American farmer $3 billion a year! If you have a problem with insects near your place, a colony of pipistrelle bats can eat hundreds of them per day - each!

1. waggle dancing
   tiptoe dancing
2. cursing each other out, bee-style

1. a parrotium
   a pandemonium
2. a whoop
   a flange

Yep, it's a pandemonium, which is very cute, of course. The weirdest collective noun, however, is probably a whoop of gorillas, which was a joke from Rowan Atkinson's breakout TV show, "Not the Nine O'Clock News" - but one that soon became popular with primatologists!

If you think you've had bad gas, you've never seen a horse with literally no way to get it out without lots of luck and possibly a human manipulating it.

1. with their mouth
   with their feet
2. with their antennae
   with their wings

Butterflies taste with their feet, a useful skill when you land on a flower and need to immediately assess whether it's a good source of food.

1. round
   spherical

   cube shaped

Wombats can poop cubes so their poop stays where they put it and doesn't roll away!

1. a dog
   a deer
2. a large rodent
   a tiny horse

A muntjac is a funny-looking little deer that comes from Africa. It was introduced to the U.K. a while ago and now it drives gardeners up the wall with its uncanny ability to get through fences.

1. They camouflage
   Their eggs hatch early if there is danger
2. Their eggs don't hatch if there is danger, keeping them innocuous
