2. TOUCH
Name: Mimosa pudica
Function:
Perceive, protect, modify.
Description:
Leaves of the sensitive
plant protect themselves
from predators and
environmental conditions by
folding in response to touch.

3. Arabidopsis
thaliana
Name: Arabidopsis thaliana
Function:
Process info, sensitivity , mechanical
forces.
Description:
Stems of wall cress are less
elongated in windy conditions due to
a touch-response system called
thigmomorpho-genesis, that turns on
specific genes in response to touch
that regulate growth.

4. PrionotusPrionotus
Name: Prionotus- Prionotus
Function:,
Taste potential food using
taste buds located on their
lips.
Description:
The long, slender fins of some
species of fish, bear taste
buds at their tips, enabling
them to taste a potential food
just by touching it.

5. Venus flytrap
Name: Venus flytrap
Function:
Chemicals, sensitivity,
process info
Description:
The rapid closure of the Venus
flytrap (Dionaea muscipula) leaf
in about 100 ms is one of the
fastest movements in the plant
kingdom.
The trap closure is initiated by
the mechanical stimulation of
trigger hairs.

6. Calliphora
vicina
Name: Calliphora vicina
Function:
Touch and mechanical
forces, sensitivity, process
info
Description:
Exoskeleton of insects
detects strain and load
change via campaniform
sensilla.

7. Passiflora
Name: Passiflora
Function:
Move, attachment, touch
Description:
Vetches and passion flowers
have modified some of their
leaves even more extremely
and converted them into
tendrils. These grope around
in space until they touch the
stem of another and swiftly
coil around it.

8. SMELL
Name: gray wolf
Function:
Process info, sensitivity,
disease
Description:
The noses of some domestic
dogs can detect some forms
of cancer in humans via an
acute sense of smell.

9. Maneater
shark
Name: Maneater shark
Function:
Process info, sensitivity,
chemicals
Description:
The nostrils of great white
sharks can detect minute
quantities of blood due to
highly sensitive nasal sacs.

10. Plantae
Name: plantae
Function:
Maintain physical integrity,
protection
Description:
The leaves of some plants
protect from webworm
caterpillars and other pests
because as they are chewed,
they release a chemical
combination of acids and
alcohols that attracts pesteating yellow jackets.

11. Orchidaceae
Name: Orchidaceae
Function:
Process info, sensitivity,
chemicals
Description:
The flowers of individual
plants of a given orchid
species improve the odds
for successful pollination by
producing a scent unique to
that plant.

12. Reptilia
Name: Reptilia
Function:
Process info, sensitivity,
chemicals
Description:
The tongues of many reptiles
help detect odors by
gathering scent particles and
transferring them to a
chemoreceptor organ.

13. Saturniidae
Name: Saturniidae
Function:
Process info, sensitivity,
chemicals
Description:
The antennae of silkworm
moths increase sensitivity
to odors because the
shape and structure of
sensillae direct air flow
through them.

14. SIGHT
Name: kingfishers
Function :
Red droplets in the cone cells
of kingfisher eyes may allow
sight through water or glare by
acting as chromatic filters.
Description:
Kingfishers have specialized
eyes and excellent eyesight.
The retina of each eye has two
fovea. The cone cells have a
high proportion of red droplets,
which may act as chromatic
filters, allowing sight through
the surface of the water.

15. Sea urchina
Name: Sea urchin
Function:
The body of purple sea urchins may
allow spatial vision due to diffuse
photoreceptors on the body surface
and spines that shield wide-angle
light.
Description:
Sea urchins don't seem to have any
problems avoiding predators or
finding comfortable dark corners to
hide in, but they appear to do all this
without eyes.
They use the whole surface of their
bodies as a compound eye, and the
animals' spines may shield their
bodies from light coming from wide
angles to enable them to pick out
relatively fine visual detail.

16. Green pitcher-plant
Name: Green pitcher-plant
Function:
Liquid found in trumpet pitcherplants digests
insects enzymatically
Description:
The hood at the top is much bigger and so
vividly coloured that it might be mistaken at first
sight for a flower.
Nectar glands cover these hoods so densely that
they glisten.
Additional glands are scattered rather more
thinly all over the outer surface of the trumpet
itself and the liquid within is more potent than
the Venezuelan marsh pitchers, for it is quite
capable by itself of digesting insects without any
help from bacteria.

17. Alabama
cavefish
Name: Alabama cavefish
Function:
The bodies of Alabama cavefish
allow them to survive without vision
via elaborate appendages and
beefed-up nerve centers.
Description:
Instead of vision, many [troglobites]
have elaborate appendages and
beefed-up nerve centers to interpret
slight air-pressure or temperature
changes, sounds, and smells.

18. Whirligig
beetle
Name: Whirligig beetle
Function:
The compound eyes of a whirligig
beetle allow clear vision in both
water and air because they are
adapted to work much like bifocal
Description:
Has compound eyes which are
adapted like bifocal glasses to see
both upwards into the air and
downwards below the water
surface.

19. Tapetum
lucidum
Name: Tapetum lucidum
Function:
The tapetum lucidum of many
vertebrates enhances night vision
by reflecting light back to
photoreceptors in the eye.
Description:
Biologic reflector system that is a
common feature in the eyes of
vertebrates.
It normally functions to provide the
light-sensitive retinal cells with a
second opportunity for photonphotoreceptor stimulation, thereby
enhancing visual sensitivity at low
light levels

20. TASTE
Name: Ictalurus punctatus
Function:
Taste buds (aprox. 250,000)
Description:
sensory organs comprised of cells
that detect the molecules that
constitute flavor, are located all
over the catfish's body.
Application:
Smoke and fire detection

21. Lepidoptera
Name: Cyprinidae
Function:
Chemoreceptors on its feet
Description:
A butterfly's taste sensors are
located on the bottom of its feet.
Application:
Food industry, biosensors,
agriculture, medical

22. Oligochaeta
Name: Oligochaeta
Function:
Chemoreceptors
Description:
Chemoreceptors are tiny sense
organs which detect chemicals in
the soil.
Application:
biosensors, agriculture.

23. Oryctolagus
cuniculus
Name: Oryctolagus cuniculus
Function:
17,000 taste buds
Description:
There are two structures on the
tongue that carry taste buds:
mushroom-shaped lobes
("fungiform papillae") and leafshaped lobes ("foliate papillae").
Application:
detect and avoid potentially toxic
plants.

24. Sus scrofa
domesticus
Name: Sus
Function:
15,000 taste buds
Description:
They use smell to communicate
with each other and can taste
whether things are good or bad for
them to eat.
Application:
detect and avoid bad tasting food.

25. HEARING
Name: Python regius
Function:
Bone conductive hearing
Description:
Sound vibrations are picked up
through the snakes jawbone, they
travel to a cochlear mechanism
within the snakes auditory system
and there transmitted to the brain.
Application:
Cochlear Americas, Baha System

26. Cyprinus
carpio
Name: Cyprinidae
Function:
The Weberian organ, three
specialized vertebral processes
that transfer vibrations in the
swim bladder to the inner ear.
Description:
The Weberian apparatus is an
anatomical structure that connects
the swim bladder to the auditory
system in fishes belonging to the
Superorder Ostariophysi.

27. Cricket
Name: Gryllus bimaculatus
Function:
have tympanums on their forelegs
Description:
Crickets can locate conspecifics by
phonotaxis to the calling (mating)
song they produce, and can evade
bats by negative phonotaxis from
echolocation calls.
Application:
Hearing aids, location of sound
sources.

28. Grasshopper
Name: Orthoptera
Function:
Have tympanums on their abdomen
Description:
The angle at which sound strikes
the slits affects the strength in
which it reaches the drum, so the
grasshopper, by waving its legs in
the air, can discover the direction
from which a call is coming
Application:
Mining, utilities, construction,
transportation,

29. Delphinus
Name: Delphinus
Function:
Dolphins have a well-developed,
acute sense of hearing.
Description:
The dolphin's auditory nerve is about
twice the diameter of the human
eighth nerve. They hear tones with a
frequency up to 160 kHz. Soft tissue
and bone conduct sound to a
dolphin's middle and inner ears.
Application:
Highly accurate medical ultrasound
machines that without the radiation
dangers and energy expenditure of
MRIs and CTs.

30. Elephas
maximus
Name: Elephas maximus
Function:
Have a hearing range between 1
and 20,000 Hz.
Description:
Elephants frequently use
infrasonic sounds, which are
sounds emitted below the
human hearing range, in long—
distance communication.
