We're going to start with a taxonomically irrelevant discussion for this one.
Some years ago, a university friend of a friend said, upon learning that my primary interest in vertebrates was amphibians and reptiles, "What, the relict groups?"
I should note that he was British.
It is easy to get the impression, in the temperate zones and particularly in Western Europe, that amphibians and reptiles as world-wide groups are insignificant and composed entirely of a few species that are clinging on. Bearing in mind that each group on its own is more diverse than the mammals, and the amphibians almost rival the birds in terms of sheer number of species, this is clearly a false impression. Having considered this, I believe that it can only be perpetuated because of two euro-centric factors:
1) Both groups are composed primarily of ectothermic species, which are usually dependant upon periods of warm weather for breeding, so relatively few species have colonised our cold and geographically
(but NOT historically) insignificant peninsula since the beginning of this most recent interglacial.
2) Members of both groups suffer disproportionately (among vertebrates) around human settlements, as they lack the dispersive ability of many birds, and unlike mammals, which have popular appeal, amphibians and reptiles both suffer (quite unjustified) persecution at the hands of many ill-informed persons who variously think they are unsightly, dangerous or even evil.
Which is why snakes could make a very good case suing the Vatican for slander.
Before this becomes a religious argument, though, onto the good news: the kind of news that has large, unblinking eyes, a scaly tail and four (often adhesive) feet.
Geckos. (

Many geckos, particularly in the tropics, enjoy a much greater respect from the human population than their less adhesive relatives elsewhere, and a number of species have come to thrive not only on the edges of human settlements, but actually within the concrete hearts, where their habits of eating various pest insects earns them a welcome place in the disused corners of the human home.
Today's species is an imperfect synanthrope, meaning that it can do well out of a certain level of human settlement, but eventually (usually at the point at which people start poisoning ants), it can no longer survive in that environment (in case you didn't work it out, it eats ants. Poisoning ants kills the individuals that then eat those ants, and starves the survivors, who have nothing left to eat. Don't poison ants if you have lizards, frogs or threadsnakes in the area).
Anyway, without further ado;
