If you want the least significant octit of the number to be first in the list, you could return (nreverse octits) instead of octits. (defun base8 (number) (do ((octits '() (cons (ldb (byte 3 0) number) octits)) (number number (ash number -3))) ((zerop number) octits)))
Size: The familiar bottlenose dolphin is around 8 feet (2.5m) long and weighs between 440-660 lbs (200-300kg). Because the forty species of dolphins are so diverse, they range in size. The smallest of the dolphin species, Maui's Dolphin, is around 4 feet (1.2m) long and weighs around 90 lbs (40 kg). The largest dolphin species is the orca, or killer whale. Male orcas grow to about 25 feet in length and weigh about 19,000 pounds. Lifespan: Most dolphins live long lives. The bottlenose dolphin can live over 40 years, and the orca can live to be 70 or 80!
River dolphins are rather small, ranging in size from the 5-foot (1.5 m) long South Asian river dolphin to the 8-foot (2.4 m) and 220-pound (100 kg) Amazon river dolphin. They all have female-biased sexual dimorphism, with the females being larger than the males.
