Dr. How's Science Wows - Hallowe'en Science Quiz

A spider has eight legs.

Although these frogs are very small (about five centimetres long) they produce a deadly toxin. Poison Dart Frogs are so named because some indigenous tribes of South America used to extract their venom and apply it to the tips of their darts. These tiny creatures are some of the most toxic animals on Earth.

Bats are mammals... just like humans; they are warm blooded, they are vertebrates, they give birth to live young and they feed their young milk!

The skin on the abdomen of a Glass Frog is transparent so we can see right through to his internal organs. Sometimes you can even see the heart beating! These frogs are very small and live high in the trees of “Cloud Forests” in Central and South America

True,the “Flying Fox” bat has a wingspan of up to 1.8 metres (five to six feet).

True... what is even more interesting is how they do it... once the female Darwin frog has hatched the eggs (about 30 of them) the male swallows them! He keep them in a pouch in his throat called the vocal pouch. The eggs are safe to develop into fully formed froglets at which stage they are spat out by Dad!

It would take us about 130 days to drive to the Moon! It takes light less than 1.5 seconds to travel between the Moon and the Earth.

Not all spiders make webs; Wolf spiders and Jumping spiders stalk and pounce on their prey.

When we see the Moon “shining” in the night sky it is just reflecting the Sun‛s rays.

True... as the Moon orbits the Earth it is also rotating on its own axis; Therefore the Moon always keeps the same side pointing towards Earth.

True... the Moon has a diameter of about 2,000 miles; most moons are very small compared with the planets that they orbit, Jupiter, for example has many moons, some of which are less than one mile wide!

Carotene is the pigment that gives pumpkins their orange colour; this pigment is also present in carrots and helps to give some of our Autumn leaves their lovely orange colour.

True (depending on who you ask!); The “Bumble Bee” bat, as the name suggests,

is not much larger than a bumble bee and weighs around two grams. This is considered the smallest mammal by skull size. However, the smallest mammal by mass is a pygmy shrew, weighing approximately 1.3 grams.

Spiders are not insects. Insects have six legs and three body segments: the head, the thorax and the abdomen. Spiders have eight legs and only two body segments: the cephalothorax and the abdomen. Spiders belong to a group of animals called “arachnids”.

The idea of carving pumpkins comes from the Celtic tradition of carving out a turnip and using it to carry home a hot ember from the bonfire. This tradition is linked to the ancient Celtic festival of Samhain.

Most people think that a pumpkin is a vegetable but it is actually a fruit; it grows on a vine and contains seeds.

There are more than 1,100 species of bats in the world. There is over 5,000 species of mammals in total!

A spider's web is made of silk proteins; Spiders use their silk not just to spin webs and catch prey but they may also use it to subdue and parcel their prey, to protect their eggs and to move themselves around.

Bats can live for 20-30 years which is quite a long lifespan compared to many other mammals.

Most frogs shed their skin once every week, particularly when they are young. Frogs will usually eat the skin that they have shed! Some species of frog can shed their skin daily.
