Green Darners are one of our largest dragonflies, and one of the easiest to recognize.

Also Green Darners are

dimorphic which means

the male and females

look different.

Their body grows over 3

inches long and has a

wing span of 4 ½ inches.

Page 3: Charlie's estuaries

The Damselfly is

talented enough to

tuck their wings onto

their back, but they

cannot walk.

Their front and

back wings

move at

different times

so they can

stop and

change

direction in air

as well as flying up to 30 miles

an hour.

Page 4: Charlie's estuaries

An adult Red – breasted

Merganser is about 51–62

cm (20–24 in) long, also

there wing span is 70–86 cm

(28–34 in) long.

A Red- breasted Merganser are a species of

bird that have a spiky crest and a long thin

bill, the Red Breasted Merganser is found in

large lakes and in the ocean. The Red

Breasted Merganser seems to like salt water

to fresh water more then the other species

of mergansers.

The Grey Plover, A.K.A

the Black-bellied Plover

lives in North America.

The Black plovers are

long distance migrants

which mean when

Black Plovers migrate

for winter they fly far far

away.

Black plovers are the

largest species of

plovers in North America.

The River Otter have special glands to

mark their territory, also the River Otter

eats on

fish, amphibians, snakes, insects, frogs, a

nd turtles.

Page 7: Charlie's estuaries

Since seals do not

migrate in some places

they are around all

year. The snout is blunt

and because harbor

seals spend so much

time underwater its

nostrils adapted to shut.

So now they have V-

shaped nostrils!

Males grow to be

about 1.4 to 2.0 m

long and 70 to 170

kg.

Woman grow to be

about 1.2 to 1.7 m and 50 to 150 kg.

Estuarine Crocodiles

can be found in a lot

of different habitats

like rivers, estuaries,

creeks, swamps,

lagoons and billabongs.

During the cooler months in the northern

territory of Australia, crocodiles are

sometimes seen sun bathing on open mud banks.

Most of the animals in an estuary live in the sea, but quite a lot of the animals in an estuary live on land.

Candiru’s are a kind of fish in Brazilian estuaries and river’s ( Amazon River )

They are very dangerous fish they measure length wise to be 40cm long (16 inches).

Candiru’s have been known to attack people when they are urinating.

Candiru’s like the warmth of your urine so they climb up your penis and can cause very serious damage.

Native Little Necked

are found from the

Aleatian islands to

Baja California even

though they are

usually a lot of them

only north of Oregon.

Little neck clams

have separate

sexes. They mature

at between 22 to

33mm or 2-3 years of age.

Hermit crabs return to

the sea to lay their

eggs. Due to that

they can not breed in

homes or animal

shelters, they need to be near the sea.

Hermit Crabs have

been heard

making croaking

noises people are

still trying to figure

out if croaking is a

kind of communication

The Hooded

Nudibranch can

grow up to be 10

cm long, 2.5cm

wide and 5cm

across the hood.

When the hooded

Nudibranch is

pulled out of

water it gives off a

sweet fruity smell.

The Hooded Nudibranch

is a carnivore. Once they

feel their prey the edges

of the tentacles overlap,

which then holds the

prey and pushes it into

the mouth.

Page 14: Charlie's estuaries

Purple Shore Crabs can

be found under rocks,

they can be found on

the west cost of North

America from Alaska to Baja in Mexico.

This crab eats sea lettuce and other green

algae and occasionally they eat dead animals.
