4 Animal Tech
Scientists searching for ways to improve
hypodermic needles are looking at
porcupine quills for inspiration .
species : a group of plants or animals with similar features
diversity : variety ; the state of being made up of many dierent things
technology : tools and knowledge used to meet a need or solve a problem
vaccine : a medicine that protects people against a disease
InTrOdUcTiOn
There are more than 5,000 species of mammals on Earth .
Mammals are animals with fur . They have live babies they
nourish with milk . They can y , swim , run , crawl , jump , and
hover . Some can even lay eggs . This diversity is why scientists
often look to mammals for ideas . They use these ideas to help solve
problems and create new technology . This is called biomimicry .
Bio means life . Mimicry is when you copy something else .
Mammals have inspired advances in all elds of technology .
By studying animals , Doctors have improved vaccines . Mammal fur
has helped make man-made fabrics warmer . Robotic arms have been
improved by studying elephant trunks . Scientists also study people
to improve technology . By studying the human brain , they improved
CAT scan machines . These machines can now map emotions . Right now ,
scientists are looking at many mammals for ideas . They want to help people
live longer , healthier , better lives .
Fur & Claws
Hypodermic needles were
invented in the 1850s . Now
they are being improved
through the study of animals .

Cockleburs may be annoying ,
but they wont harm animals
unless they are swallowed .

Velcro
engineer : a person who plans and builds tools , machines , or structures
cocklebur : a owering plant with round , spiky pods that hold its seeds
Have you ever gone out walking with your dog and noticed small
pieces of plants sticking to his legs ? This happened to Swiss engineer
George de Mestral .
One day , de Mestral returned from a hike . He noticed cockleburs
stuck to his dogs fur . He became curious about them . The burs were
able to hold fast . But they could be pulled o fairly easily . He decided to
study them .
Burs can latch and unlatch from fur very easily . But it took him years
to understand how they worked . Once he did , he decided to make a version
himself . After years of work , he invented Velcro in 1955 . Velcro comes
from two French words , velour and crochet , which mean velvet and hook .

Velcro
The company VELCRO
now makes 35,000
dierent products .
LeSsOnS fRoM NaTuRe
The outside of a cocklebur is covered in thousands of little hooks . Tangled
animal fur forms tiny , soft loops . When an animal brushes against a cocklebur ,
the hooks fasten onto the soft loops . Velcro is made of two sides . One side has
hook-like barbs . The other one has soft loops . The two sides latch when they
are pressed together .
8 Animal Tech
The tiny hooks on a cocklebur allow it to latch onto an
animal . When the animal scratches or bites it o , or
brushes against something else , the bur falls to the ground .
At rst , de Mestral made Velcro to replace
zippers and buttons on clothes . Both sides were
made of cotton . But the cotton hooks gave out after
