What Small native cat to North and South America did Carl B. Koford make studies on in the 50's and 70's?
Jaguarundi The jaguarundi ("Puma yagouaroundi") ( ) or eyra cat is a small wild cat native to southern North America and South America. It has been listed as Least Concern on the IUCN Red List since 2002. Its presence in Uruguay is uncertain. The megareserves of the Amazon Basin are probably the only conservation units that can sustain long-term viable populations.
Leopard catshark The leopard catshark ("Poroderma pantherinum") is a species of catshark, and part of the family Scyliorhinidae, endemic to the coastal waters of South Africa. Abundant in inshore waters under 20 m deep, this bottom-dweller favors rocky reefs, kelp beds, and sandy flats. Growing to a length of 84 cm , the leopard catshark has a stout body with two dorsal fins placed well back, and a short head and tail. It is extremely variable in color and pattern, with individuals ranging from almost white to black and covered by diverse patterns of black spots, blotches, rosettes, and/or lines. The color pattern changes with age and some forms seem to be location-specific, suggesting the presence of multiple distinct, local populations. In the past, some of the more distinct color forms have been described as different species.
