A.K.RAAHA SUTHAIII UG PHYSICS
13PHY040
EXORDIUM:
HEBITAT:1.Wet low areas of eastern Canada.
2.Northeastern United states.3.Atlantic coast
4.Southeastern Georgia
Range of star nose moleThey prefer damp to
Saturated soil.
These species like to inhabit in the wet areas, wet meadows, lakes, streams and banks. These
moles create tunnels underneath the water.
SCIENTIFIC CLASSIFICATIONKingdom AnimaliaPhylum ChordataClass MammaliaOrder EulipotyphiaFamily TalpidaeSubfamily ScalopinaeTribe Condylurini(Gill-
1872,1875)Genus Condylura(Illiger-1811)Species C.CristataBionomical name Condylura cristata
MORPHOLOGYStar nosed mole is covered with thick, blackish-
brown water repellent fur.Large scaled feet and thick tail (fat storage
reserve for spring breeding season)Adults: Length=15-20cm, Weight=55grams,
Teeth=44Rays: 22 mobile, pink, fleshy, tentacles at the
end of the snout.These rays are used to identify the food by
touching.
REPRODUCTIONStar nosed mole usually mate in the middle of
March and April.The females reproduce only once a year.
However, the females may also reproduce for the second time at an unsuccessful first time.
Each litter contains 2 to 7 babies.
AT PARTURITIONEach offspring about 5cm long, hairless,
1.5gram weight.Their eyes, ears, stars are sealed, only opening and becoming useful about 14 days after birth.
They become independent after 30 days.They fully matter after 10 months.
STAR NOSE:Sensory motor organ shaped by 22 fleshy finger
like appendages or tendrils.It is larger than the other mole species noses.
The snouts are lined with 25,000 minute sensory receptors. It is helpful for the mole feel
its way through its underground lair.These are help to kill its prey with
in 120 milliseconds.
AMAZING ADAPTATIONIt is a fastest eating mammal. They are almost
being blind.The Star-Nosed Mole’s adaptation has occurred because its poor-sighted eye could result in the
species to extinction because it won’t be able to hunt its prey.
The mole lives in dirt, so it should be dirty.It’s prey is too fast for it.
Its nose prevent the dirt from entering nose and mouth. Without its
nose, it would not be able to survive in its
habitat. The nose of these species act, as a powerful sensory
organ because these help them to see.
Life span 3-4 years.
INCREDIBLE MATTERThe Guinness Book of World Record has stated that these species are in the list of one of the
fastest hunters.The tentacles of these species are six times faster
when compared to the human hand.The blackish brown fur of these species helps them to be warm during winter. This prevents
freezing of their body.
FASHION Color Blackish brownSize 15-20cmWeight 55 gramBody Long tail, water
resistant furLegs Four legs dotted
with scalesHead Not clear visionTeeth 44Nose Like a star
HABITUDEThese species dwell in both wet areas as well as
land surface.They can swim long distances in search of prey.
However, like to spend several hours on the land surface.
These species are active during both day and night and even during winter
They prefer to live together forming colonies.
FOODThese species like
to have small insects & fishes.
At other times, they can also go for ants, beetle
snails, and mollusks for their
diet.

TYPES OF PROPORTION
FACTSC.cristata are the only mole species that live in
the wetlandsC.cristata are not currently endangered, but
humans are expanding and destroying the wetlands
They could be at risk in the future. C.cristata can consume its body weight in
worms and insects in a single day.The star shaped nose on C.cristata has over
160,000 touch sensors per square inch
Star nosed mole are looking ugly. So don’t neglect them. They are useful for human. Don’t let them like dinosaurs to destroy
