(20) The following order of animal sera was defined in comparison to human sera: cattle, pigeon, duck, sheep, cat, turkey, swine, coypu, hen, dog.
Crepuscular
Definition:
(a.) Alt. of Crepusculous
Example Sentences:

(3) "Late" like the autumnal, musical Eliot of Four Quartets; like the demanding, crepuscular Beethoven quartet the film's characters rehearse for their silver-anniversary performance (String Quartet No 14 in C sharp minor – menacingly referred to as "Op 131"); and "late" in the connected senses of former or dead, which this quarrelsome foursome soon might be if they fail to recover their harmony.
(4) To describe his work in progress, he jotted down a list of hyperbolic adjectives: "Astounding, extraordinary, surprising, superhuman, supernatural, unheard of, savage, sinister, formidable, gigantic, savage, colossal, monstrous, deformed, disturbed, electrifying, lugubrious, funereal, hideous, terrifying, shadowy, mysterious, fantastic, nocturnal, crepuscular."
(5) Hourly sampling with human bait showed a bimodal pattern, with a greater peak in the evening crepuscular period.
(6) Malaise-trapped females showed a distinct crepuscular peak of host-seeking activity.
(7) Whereas in humans the retinal sampling frequency approaches the optical cut-off frequency quite closely, in diurnal insects of both types the image is undersampled by a factor of 2-3, and in crepuscular spiders this factor may be greater than 100.
(8) Paranoid reaction may get closer to hysterical crepuscular states.

(10) Errol Morris , a respected documentarian himself and one of the film's executive producers (along with Werner Herzog ), defended the film on the grounds that "by re-enacting the murders … [we] could become reconnected to a history that had nearly vanished into a crepuscular past."
(11) The superposition eye of the cockchafer, Melolontha melolontha, exhibits the typical features of many nocturnal and crepuscular scarabaeid beetles: the dioptric apparatus of each ommatidium consists of a thick corneal lens with a strong inner convexity attached to a crystalline cone, that is surrounded by two primary and 9-11 secondary pigment cells.
(12) We found that the gerbil in captivity, unlike most rodents that are nocturnal, is a crepuscular animal, being more active at the transitions between light and dark.
