Male smooth newt on land.

We have a thriving smooth newt Triturus vulgaris population, mainly
occupying one of our smaller ponds only 8 foot(2.44m) by 3 foot(0.91m)
in size and about 1 foot 3 inches(38cm) deep. I should point out
that these newts are by no means local in origin, although the
species does inhabit our part of the world. The ancestors of our
colony were collected about 5 years ago from the garden of some
friends in Scotland, where they are present in large numbers. I
must point out that it is always unwise to move wild creatures
out of their native habitat and into another, unless you are
absolutely sure of the following two conditions.
1. That they are in abundance at the
place of collection and that the numbers taken are so small as to
have no effect on the population as a whole.
2. That they do already occur locally to
the place of introduction or have been present there in the past
few decades.

We actually only introduced about 6
individuals and now have somewhere between 30 and 50. They spawn
every year, laying eggs singularly around which the female wraps
the leaves of pond plants to conceal them. The breeding season
differs from frogs in that it seems to extend over as much as
three months in some years. Occasionally we collect a few of the
newly hatched newts and place them in a small fish tank in our
kitchen window. From there we can observe them closely and study
their development and feeding habits. They are voracious little
creatures preying on anything that moves and is small enough for
them to consume. The adults have the same appetite. I have seen a
worm in wet weather trying to make it's way across the duckweed
covering the pond surface only to be suddenly dragged below by a
lurking newt.

Male smooth newt under water.

Immature smooth newt, known as an eft,
about 1 inch (2.5cm) long. This individual was photographed in early
March and has overwintered in the pond and still possesses gills,
although, as can be seen, all legs are developed. Quite often the later
produced youngsters survive this way not having enough time to fully
develop before the weather turns cold.

Male displaying to female, male is darker and
to the right, notice also the heavier webbing on the rear toes. I never
appreciated how difficult it was to photograph creatures below the
surface. Our eyes and brain allow us to see through or past the surface
reflections, the camera does not have that ability. I was just lucky
with this one, enough shadow on the water to stop most of the
reflection.

An eft just before losing it's gills
photographed in the aquarium on our kitchen window. The only food added
was tropical fish flakes, however the water did come from the pond and
probably contained other small creatures which would have provided food.

This is one little fellow about to venture
into the ever so big wide world, well a small pond in my garden to start
with.
