Main predators are birds, omnivorous/carnivorous mammals, fish, other amphibians, & garter snakes/ribbon snakes.
 
In spring, females lay 200-400 eggs. Eggs hatch in 2-5 weeks, living as aquatic larvae for 2-5 months. After 3 months, larvae shed gills & move onto land living as red efts (terrestrial juvenile stage)-efts metamorphose into mature aquatic adults at 2-3 years old. Some populations remain in eft stage permanently, only entering water to breed. Neoteny (gilled individuals reaching sexual maturity) has also been documented. Some populations skip eft stage.
 
Courtship involves males wiggling/moving tails as well as emitting pheromones.
 
Sometimes kept as pets.
 
Mating balls sometimes observed w/ multiple males fighting over/mating w/ single female.

Fun Fact(s):
Adults & efts have poisonous skin but skin of red efts more poisonous w/ bright coloration serving as warning. Toxin is a sodium channel blocking tetrodotoxin.
 
If water sources dry up, aquatic newts can revert to being land-based adult efts as survival strategy.

    Just use the graphite powder by squeezing it
    out in the lock. However they must be ready to work weekends installing programs,
    and to be known as out at any hour to ‘rescue’ folks who have locked
    themselves out. You may throw together an absurd hack in an hour

    He took my title and handle (and my accuser made a note of them), and
    that, so far as I was involved, finished the business. I took up my
    basket and went forth a free boy in company with my pal the police
    man. In Great Marlborough Street we parted, he to return to his beat, and
    I to the remainder of my round of deliveries.

    So ended an incident that had, at one time, appeared quite threatening. And
    but it had probably not ended. Perhaps no incident ever does truly end. For
    each antecedent begets penalties. Coming occasions forged their shadows
    earlier than them; however those shadows normally remain invisible until the occasions
    which have forged them have, themselves, come into view. Indeed, it befalls
    thus almost from necessity; for how can a shadow be recognized otherwise
    than by comparison with the substance?

    But I shall not right here anticipate the later passages of my story. The
    consequences will emerge of their correct place. I might, nonetheless, refer
    briefly to the more quick reactions, though these also had their
    significance later. The little e book which I had bought (and paid for the
    same evening) was a treatise on clocks and locks by that incomparable
    master of horology and mechanism, Edmund Beckett Denison (later to be
    known as Lord Grimthorpe). It was a useful e-book, and it grew to become my
    chiefest treasure. Carefully wrapped in a protecting cowl of brown
    paper, the precious quantity was henceforth my constant companion. The
    abstruse mathematical sections I had regretfully to cross over, however the
    descriptive elements have been learn and re-read till I could have recited them
    from reminiscence. Even the drawings of the good Westminster Clock, which had
    at first appeared so bewildering, grew to become intelligible by repeated study,
    and the intricacies of gravity escapements and maintaining powers grew
    easy by familiarity.

    Thus did the revered E. B. Denison add a new delight to my life. Not
    only was every clock-maker’s window a thing of beauty and a provider
    of quiet pleasure, but an object so lowly as the lock of the scullery
    door–detached by Uncle Sam and by me rigorously dismembered–was made
    to furnish an leisure compared with which even the Punch and Judy
    present paled into insignificance.

    CHAPTER III. OUT OF THE NEST

    A Certain philosopher, whose name I can’t recall, has, I understand,
    found that there are several totally different sorts of time. He isn’t
    referring to those that are identified to astronomers, similar to sidereal mean
    or apparent time, which differ solely when it comes to measurement, but to time
    because it affects the young, the center-aged and the old.

    The invention shouldn’t be a brand new one. Shakespeare has instructed us that “Time
    travels in divers paces with divers individuals “, and, for me, the poet’s
    assertion is extra to the purpose (and maybe more true) than the
    philosopher’s. For I’m considering of 1 “who Time ambles withal “, or
    even “who he stands nonetheless withal”; to wit, myself in the capability of Dr.
    Pope’s bottle-boy. That stage of my existence seemed, and still seems,
    looking again on it, to have lasted for half a life-time; whereas it
    occupied, in actual fact, however a matter of months.

    It got here to an end when I used to be about thirteen, principally by my own act. I
    had begun to feel that I used to be making unfair inroads on the family
    resources, for, though the school that I attended was an affordable one,
    it was not one among the most cost effective. Aunt Judy had insisted that I ought to have
    an honest schooling and not mix with boys below our own class, and
    accordingly she had despatched me to the varsity carried out by the clergy man of
    our parish, the Reverend Stephen Page, which was attended by the sons of
    the native shop-keepers and higher-class working males. But modest because the
    faculty charges have been, their payment entailed some sacrifice; for, though we
    were not poor, still Uncle Sam’s earnings as a journeyman cabinet-maker
    have been only thirty shillings per week. Old Mr. Gollidge, who did mild jobs
    in a carpenter’s shop, made a small contribution, and there was
    half-a-crown every week from my wages; however, when all was said, it was a tight
    match and will need to have taxed Aunt Judy’s powers of administration severely to
    maintain the standard of consolation wherein we lived.

    Moved by these considerations (and maybe influenced by the monotonous
    alternation of college and bottle-basket), I ventured to place the case to
    Aunt Judy and was relieved to seek out that she took my options critically
    and was clearly pleased with me for making them.

    “There’s something in what you say, Nat,” she admitted. “But remember
    that your schooling has got to final you for all times.
