Fat Bottom Girls. Some mature female Guyana boas can grow to 13 feet and weigh 60 pounds or more, although the average size is more typically between 8 to 10 feet. The longest boa recorded was 18 feet long but may have been an anaconda. Male Guyana boas are 1 to 2 feet shorter than females and not as bulky. Newborns are about 22 inches long and may reach 4 to 5 feet by their first birthday. Growth rate slows after the second year. Guyana boas continue growing for life, which can be 25 to 30 years.
