fer de lance (n.): large poisonous snake of American tropics, 1817, from French, "lance-head," literally "iron of a lance." So called for its shape.
python (n.): 1580s, fabled serpent, slain by Apollo near Delphi, from Latin Python, from Greek Python "serpent slain by Apollo," probably related to Pytho, the old name of Delphi, perhaps itself related to pythein "to rot," or from PIE *dhubh-(o)n-, from *dheub- "hollow, deep, bottom, depths," and used in reference to the monsters who inhabit them. Zoological application to large non-venomous snakes of the tropics is from 1836, originally in French.
shark (n.): 1560s, of uncertain origin; apparently the word and the first specimen were brought to London by Capt. John Hawkins's second expedition (landed 1565; see Hakluyt).
There is no proper name for it that I knowe, but that sertayne men of Captayne Haukinses doth call it a 'sharke' [handbill advertising an exhibition of the specimen, 1569]
The meaning "dishonest person who preys on others," though attested only from 1599 (sharker "artful swindler" in this sense is from 1594), may be the original sense, later transferred to the large, voracious marine fish. If so, it is possibly from German Schorck, a variant of Schurke "scoundrel, villain," agent noun of Middle High German schürgen (German schüren) "to poke, stir."

But on another theory, the English word is from a Mayan word, xoc, which might have meant "shark." Northern Europeans seem not to have been familiar with sharks before voyages to the tropics began. A slightly earlier name for it in English was tiburon, via Spanish (where it is attested by 1520s), from the Carib name for the fish.

The English word was applied (or re-applied) to voracious or predatory persons, on the image of the fish, from 1707 (originally of pick-pockets); loan shark is attested from 1905. Sharkskin (1851) was used for binding books, etc. As the name of a type of fabric held to resemble it, it is recorded from 1932.
There is the ordinary Brown Shark, or sea attorney, so called by sailors; a grasping, rapacious varlet, that in spite of the hard knocks received from it, often snapped viciously at our steering oar. [Herman Melville, "Mardi"]
torrid (adj.): 1580s, in torrid zone "region of the earth between the tropics," from Medieval Latin torrida zona, from fem. of torridus "dried with heat, scorching hot," from torrere "to parch," from PIE root *ters- "to dry" (see terrain). Sense of "very hot" is first attested 1610s. Figurative sense from 1630s.
tropic (n.): late 14c., "either of the two circles in the celestial sphere which describe the northernmost and southernmost points of the ecliptic," from Late Latin tropicus "of or pertaining to the solstice" (as a noun, "one of the tropics"), from Latin tropicus "pertaining to a turn," from Greek tropikos "of or pertaining to a turn or change; of or pertaining to the solstice" (as a noun, "the solstice," short for tropikos kyklos), from trope "a turning" (see trope).

The notion is of the point at which the sun "turns back" after reaching its northernmost or southernmost point in the sky.

The 10c. Anglo-Saxon treatise on astronomy translates Latin quinque zonas as fyf gyrdlas.
