specimen found of the dolphin. Sir James lived

science and was really into learning about nature

Extra!
HOW YOU CAN TELL HOW OLD A DOLPHIN IS When a
dolphin is born it has teeth and each 1 year it
grows older.Then it grows a layer of this stuff
you call hollow cones, and if you cut a tooth off
a dolphin you can see how old that dolphin is by
counting the hollow cones but this hollow cone
can also be called annual rings just like the
ones on trees.Each time when it grows a layer
one will be dark and next year 1 will be
light. If you see a dolphin with white scars on
their skin that means that,that dolphin has been
attacked by a shark!And if it has dark grey ones
it means that that dolphin has skin disease.

KEEPING WARM (EXTRA )
Water conducts heat more effectively than air.In
baths at 20 celsius you would eventually die from
exposure.Marine mammals maintain a high body
temperature of 36-37 celsius.So insulation is a
real problem.Seals solve the problem with two
layers of fantastic fur,the inner layer so dense
than the skin never gets wet.Dolphins and whales
use blubber , a dense oily fat layer just under
the skin,2-3 centimetres thick in hector
dolphins and up to 50 centimetres thick in some
whales.
12
Lifespan
Hectors dolphins mature at about 8 years and
they live around to 15-18 years to they die.
13
Prey Of Hector's Dolphins
Hectors dolphin spend most of their feeding time
by chasing prey that live on or near the bottom
of the ocean.Scientist have studied hard at the
stomach contents of dead dolphins.Conveniently,som
e hard parts of their prey,such as the air bones
of fish and the breaks of squid,on the west coast
diet of the Hectors dolphin is the arrow
squid,ahuru,hoki and hake.On the east coast they
eat arrow squid,ahurusprat,stargazer,yellow eyed
mullet,sole and red cod.

Calves of hectors dolphin are born they need
company so the calves stay very close to their
mother till their old enough to protect
themselves.
