(n.) A nocturnal carnivorous mammal (Cercoleptes caudivolvulus) of South America, about as large as a full-grown cat. It has a prehensile tail and lives in trees. It is the only representative of a distinct family (Cercoleptidae) allied to the raccoons. Called also potto, and honey bear.
Example Sentences:
(1) Electroretinogram (ERG) flicker photometry was used to measure the spectra of the cone photopigments for members of two nocturnal species, the raccoon (Procyon lotor) and the kinkajou (Potos flavus), and a diurnal species, the coati (Nasua nasua).
(2) Whereas the raccoon and kinkajou are monochromatic, the diurnal coati is a dichromat having an additional class of cone photopigment with peak sensitivity close to 433 nm.
(3) It was possible to correlate skin depigmentation with the course of leishmanial infection in one animal, a young kinkajou, Potos flavus.
(4) Since the termination of pyramidal tract fibers on or very near spinal motor neurons is a prerequisite even for the peculiar kind of dexterity seen in some non-primates (e.g., raccoon, kinkajou), this one feature alone seems to be a critical factor.
Potto
Definition:
(n.) A nocturnal mammal (Perodictius potto) of the Lemur family, found in West Africa. It has rudimentary forefingers. Called also aposoro, and bush dog.
(n.) The kinkajou.
Example Sentences:
(1) A female Perodicticus potto developed a subcutaneous spherical mass on the medial aspect of the inguinal area.
(2) However the metabolic rate of Aotus is not reduced to the extent found in two hypometabolic prosimians Perodicticus potto and Nycticebus coucang.
(3) The karyotypes of two Lorisidae (Prosimians) Nycticebus coucang and Perodicticus potto have been studied, using many banding techniques.
(4) As these few cones seem to activate the bipolar cells nearly as effectively as the numerous rods, it is suggested that these cones may be responsible for day vision in the potto.
(5) In tree shrews and galagos muscle is heavier (35%) than in pottos and slow lorises (below 28%), but bone and skin are lighter.
(6) Convergences in segment pattern (sloths with pottos and lorises, marmosets with tree shrews, owl monkeys with galagos, cebus with macaques) as well as divergences are documented.
(7) In a cold environment the daily urinary excretion of catecholamines of the tropical but cold hardy potto is only moderately increased.
(8) Nevertheless in potto the critical fusion frequency is higher for red light than for blue light.
(9) A spherical mass on the medial aspect of the thigh and caudal abdomen of a 15-year-old female Perodicticus potto was surgically removed and shown to be a myeloliposarcoma.
(10) There is histological evidence for the presence of cones in potto's retina: about 1 cone for 300 rods.
(11) The dopamine, dopac and tyrosinehydroxylase contents of the caudate nucleus in the prosimian Perodicticus potto and in the simii Macaca mulatta and M. fascicularis have been estimated.
(12) The following species were represented: Potto, Senegalgalago, wooly monkey, black spider monkey, common marmoset, cottonhead tamarin, pigtailed macaque and lesser whitenosed guenon.
(13) The concentrating ability of the kidney in Perodicticus potto was investigated.
(14) The same carcinogen applied to the skin of pottos (Perodicticus potto) caused death in 6 of the 7 animals within 9 weeks.
(15) In the potto's retina some red sensitive elements respond to wavelenghts beyond those which affect visual purple.
(16) Bromine is unexpectedly high in the potto tumor, in other tumor analyses reported in the literature, as well as in the only available embryonic tissue from the female potto, a placenta.
(17) On comparison of the West African potto with two other prosimian myoglobins known so far, there were 12 differences between the potto and the galago (East African) and 18 differences between the potto and the sportive lemur (Madagascar).
(18) The results do not support the hypothesis according to which the sluggishness of the potto is somehow related to a low dopamine content of part of the extrapyramidal system as found in the Parkinson-syndrome.
(19) Based on our observation that the potto may excrete uric acid in fairly high concentrations, the partition of nitrogen in the urine was also explored.
(20) The primary structure of the myoglobin of the prosimian Lorisidae Perodictius potto edwarsi (potto) was studied.
