Description
The testes of an adult Opisthorchis viverrini are lobed in comparison of dendritic testes of Clonorchis sinensis.
The eggs of Opisthorchis viverrini are 30 × 12 μm in size and they are slightly narrower and more regularly ovoid than in Clonorchis sinensis. But eggs of Opisthorchis viverrini are visually indisgushiable in Kato technique smears from other eggs of flukes from other fluke family Heterophyidae.
The metacercariae of Opisthorchis viverrini are brownish, elliptical with two nearly equal-sized suckers: the oral sucker and the ventral sucker. They are 0.19-0.25 × 0.15-0.22 mm in size.

Famous quotes containing the word description:
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
