Title: ENDANGERED SPECIES


1
ENDANGERED SPECIES
  • Los alumnos de 7mo junto a la profesora Paola
    Capresi realizaron un trabajo de investigación
    sobre determinadas especies en extinción.
    Buscaron información en páginas web, armaron un
    documento de power point y luego expusieron sus
    trabajos en forma oral. Estos son algunos de sus
    trabajos

The Gorilla
By Gonzalo Finkelstein ann Gonzalo Mastromonaco
3
Where do gorillas live and which are their
habits?
4
Gorillas live in the African jungle and they are
true forest animals. The gorilla has diurnal and
terrestrial habits. They spend most of the day
eating and sleeping.
5
what are they like?
6
They weigh between 120 and 182 kilograms. Those
mammals are from 1.6 meters to 2 meters.
7
How do gorillas classify?
8
Gorillas are classified in two groups the
Western gorilla and Eastern gorilla. The Western
gorillas are also classified in two groups the
Western lowland gorilla and the Cross River
gorilla. The Eastern gorillas are classified in
two groups, too the Mountain gorilla and the
Eastern lowland gorilla.
9
Why are gorillas endangered?
10
Gorillas are endangered because hunters have
hunted them for a long time and they have
destroyed their home.

Loggerhead Sea Turtles by Paula, Sol and
Candela.L.M
12
Where do they live?
  • This turtle lives in the tropical, subtropical
    and temperate regions of the Atlantic, Pacific
    and Indian Oceans. To the North it goes to
    Terranova, Britain and Japan. And in the South
    off to Chile and South Africa. the distribution
    includes the Mediterranean Sea. Its common in
    the north off the costs of Australia.

13
The birth of a turtle
  • The pairings begins when the male swims to the
    female and he touches her face with his front
    claws.
  • The gestation period last 2 months but if the
    female doesnt find a place to put her eggs she
    retains it and it lasts longer.
  • The incubation period of the mayor turtles is
    about 45 days , but the development of the eggs
    depends on the temperature of the nest. If the
    temperature of the nest is cold it could take 8
    more days. Turtle sex is define by the
    temperature.

14
Why is this turtle endangered?
  • Poaching
  • Collection of eggs for consumption
  • Bycatch
  • Development of coasts
  • Sea ??pollution

The tomato frog by Dylan, Joaquin and Marcos
19
there are four species of tomato frogs
Dyscophus antongilii, D. insularis, D. guineti
and D. philippensis. Three of the fours species
are native to Madagascar.
20
When they feel threatened, tomato frog inflates
its body. If a predator grabs a tomato frog in
the mouth, the skin of the frog secretes a sticky
substance that sticks to the eyes and mouth of
the predator, causing the predator to release the
frog to release their eyes.
21
The life of the tomato frog can be 6-8 years. As
an adult, colors may vary from yellowish orange
to dark red. Tomato Frogs will reach sexual
maturity in 9-14 months.
  • Females are larger than males and can reach 4
    inches in length. Most women are reddish-orange
    bright dark red. The bellies are usually
    yellowish, and sometimes there are black spots on
    the throat.
  • Males can reach 2-3 inches long. Men are not as
    bright , but more of a dull orange or
    orange-brown.

22
They are also on the list of endangered species.
They breed in the rainy season and are nocturnal.
They tend to eat small insects and invertebrates.

HEDGEHOG by Julieta and Sofia
25
Definition
  • Hedgehogs (Erinaceinae) are a subfamily of small
    mammals covered with spikes, belong to the order
    Erinaceomorpha. It feeds on insects. There is a
    total of 16 species divided into 5 groups.

26
Features
  • Hedgehogs are considered very solitary animals,
    they seek only to procreate. They are nocturnal,
    they do not like sunlight. They are very quiet,
    but they can appear sullen under excessive noise
    or show signs of stress when they are handled
    too. The males are usually more complicated and
    sullen than females.
  • Their body is small, it fails to exceed 16 inches
    long and it weighs between 300 and 400 grams, its
    outer armor is full of spikes. that can measure
    up to 2.5 inches in adults. The color of their
    spines usually alternates between brown and
    white. Thanks to this defense system, the
    Hedgehog turns into a ball full of sharp
    stilettos that can save your life when attacked
    by a predator.
  • The hedgehog teeth comprises 36 teeth which also
    serve to defend. Its pointed snout helps identify
    hidden odors. The facial area, the belly and the
    s legs are barbed exempt areas.

27
Habitat
  • Hedgehogs live in Europe, Asia, Africa and have
    been introduced in New Zealand. In Spain there
    are two species, the European hedgehog and the
    eared hedgehog, but the eared hedgehog is very
    common in captivity.

28
Feeding
  • The hedgehog eats insects and molluscs, and
    doesnt hesitate to attack snakes found in their
    way, to whose venom is not immune against what
    was formerly believed. It also eats various
    vegetables.

29
Reproduction
  • The breeding season lasts from April to August.
    Females can have several litters at this time.
    The males chase the females for hours waiting to
    be receptive and relax their quills. After
    copulation the male abandons its offspring.
    Gestation lasts between one and a half months and
    the hatchlings will be between 1 and 9 spikes,
    blind and covered by skin. They open their eyes
    at two weeks and will nurse for the first month.
    At 10 months they reach sexual maturity.

30
Wintering
  • In late fall dormancy begins at the bottom of a
    burrow warm and dry, protected by a layer of
    leaves.

31
Their predators
  • As it is a nocturnal animal, most deadliest
    predators are nocturnal too The owl, dogs,
    wolves, foxes, dangerous snakes, badgers.

32
Our opinion
  • Our view is that while, in some places they are
    domesticated, we reflect that it is a wild animal
    and it is comfortable in its natural habitat.
    Since one of the species of hedgehog (Moorish) is
    in danger of extinction, we should generate an
    awareness to care of this animal.

SEAHORSE by Florencia Rios, Jazmin Berezovsky
and Victoria Fernandez
  • Type Fish
  • Diet Carnivore
  • Average life span in the wild
  • 1 to 5 years (estimated)
  • Size 0.6 to 14 in (1.5 to 35 cm)
  • Group name Herd
  • Did you know?
  • Seahorses have no teeth and no stomach. Food
    passes through their digestive systems so
    quickly, they must eat almost constantly to stay
    alive.
  • Size relative to a tea cup

34
Seahorses are truly unique, and not just because
of their unusual equine shape. They are
monogamous and mate for life. Rarer still, they
are among the only animal species on Earth in
which the male bears the unborn young. Found in
shallow tropical and temperate waters throughout
the world, these upright-swimming relatives of
the pipefish can range in size from 1.5
centimeters to 35 centimeters long.
35
Male seahorses are equipped with a brood pouch on
their ventral, or front-facing, side. When
mating, the female deposits her eggs into his
pouch, and the male fertilizes them internally.
He carries the eggs in his pouch until they
hatch, then releases fully formed, miniature
seahorses into the water.
36
They anchor themselves with their prehensile
tails to sea grasses an, using their elongated
snouts to suck in plankton and small crustaceans
that drift by. Voracious eaters and they can
consume 3,000 or more brine shrimp per day.
37
Population data for most of the worlds 35
seahorse species is sparse. However, worldwide
coastal habitat depletion, pollution, and rampant
harvesting, mainly for use in Asian traditional
medicine, have made several species vulnerable to
extinction.
38
There are many divers groups or associations that
are looking for financial support and making
campaigns to save sea horses from extinction.
But we can make a difference too!!!

He eats fish and squids. In August begins the
breeding season. During this time they are with
the same specie.
43

44
In this time they live in forests.
45
This animal is a bird.
46
The animal has a length of 66 to 70 cm. His
weight is about 8 kg. He is in danger because of
predators as cats and weasels.
47
They can dive to two metres and they run away to
15 km from the coast. Humans know that they have
been in the world from 126 thousands of years.
