Final answer:
The revised and corrected sentence is 'The zoo's new Dark-Spotted Anaconda is 7 feet long,' which includes proper hyphenation and numeral usage. Anacondas are large snakes, and like others, they utilize belly scales to move and molt to maintain skin health.
Step-by-step explanation:
The correct sentence that preserves the intended meaning while making the appropriate revisions is: The zoo's new Dark-Spotted Anaconda is 7 feet long. This sentence revision corrects the original by hyphenating Dark-Spotted to properly form the compound adjective and by using the numeral 7 instead of spelling it out, which is generally preferred for measurements in scientific and technical writing. Additionally, the use of numerals helps to make the length stand out more clearly to the reader.
Anacondas such as the Dark-Spotted Anaconda are among the largest snakes, capable of reaching lengths far exceeding 7 feet, with some species, like the Green Anaconda, averaging around 17 feet in length. Like most snakes, anacondas have specialized belly scales that aid in movement. Furthermore, snakes undergo molting, a process that involves shedding the entire outer layer of skin in one piece. This molting process serves multiple purposes, including allowing the snake to grow, replacing old and worn skin, and removing parasites like mites and ticks.
