spectacled caiman

MaryW commented on the word spectacled caiman

There are many poxviruses in nature, and they infect species that gather in swarms and herds, circulating among them like pickpockets at a fair. There are two principal kinds of pox viruses: the poxes of vertebrates and the poxes of insects. Pox hunters have so far discovered mousepox, monkeypox, skunkpox, pigpox, goatpox, camelpox, pseudocowpox, buffalopox, gerbilpox, several deerpoxes, chamoispox, a couple of sealpoxes, turkeypox, canarypox, pigeonpox, starlingpox, peacockpox, sparrowpox, juncopox, mynahpox, quailpox, parrotpox, and toadpox. There's mongolian horsepox, a pox called Yaba monkey tumor, and a pox called orf. There's dolphinpox, penguinpox, two kangaroopoxes, raccoonpox, and quokkapox. (The quokka is an Australian wallaby.) Snakes catch snakepox, spectacled caimans suffer from spectacled caimanpox, and crocodiles get crocpox. . . .

Insects are tortured by poxviruses. There are three groups of insect poxviruses: the beetlepoxes, the butterflypoxes (which include the mothpoxes), and the poxes of flies, including the mosquitopoxes. Any attempt to get to the bottom of the insect poxes would be like trying to enumerate the nine billion names of God.

. . .

. . . The insect poxes may have arisen in early Devonian times, long before the age of dinosaurs . . . when . . . the first insects were evolving. . . .

At least two known midgepoxes torment midges. Grasshoppers are known to suffer from at least six different grasshopperpoxes. If a plague of African locusts breaks out with locustpox, the plague is hit with a plague, and is in deep trouble. Poxviruses keep herds and swarms of living things in check, preventing them from growing too large and overwhelming their habitats.
