3.
What long do adult manatees grow?
Correct Answer
C. 9-10 feet
Explanation
Adult manatees can grow up to 9-10 feet in length. Manatees are large marine mammals that can weigh up to 1,200 to 1,800 pounds. They have a round, cylindrical body shape and a paddle-shaped tail. Their size allows them to navigate through shallow waters and graze on aquatic plants. Manatees have a slow growth rate, and it takes several years for them to reach their full adult size.
4.
Do manatees have snouts with whiskers?
Correct Answer
A. Yes
Explanation
Manatees do have snouts with whiskers. Snouts are elongated, flexible, and sensitive, allowing them to explore their surroundings and locate food. The whiskers, or vibrissae, are located around the snout and are used to detect movements and vibrations in the water, helping the manatees navigate and find food. These specialized features are important adaptations for their aquatic lifestyle.
5.
How far north do manatees usually go during the summer months?
Correct Answer
B. Virginia
Explanation
Manatees usually do not go as far north as Maine or New York during the summer months. While they may occasionally be spotted in North Carolina, Virginia is the farthest north that manatees typically travel during this time.
6.
Is it true that manatees do not tolerate temperatures below 68 degrees for extended periods of time?
Correct Answer
A. True
Explanation
Manatees are known to be sensitive to cold temperatures. They are warm-water marine mammals and prefer water temperatures above 68 degrees Fahrenheit. When exposed to colder temperatures for extended periods, manatees can experience cold stress, which can lead to health issues and even death. Therefore, it is true that manatees do not tolerate temperatures below 68 degrees for extended periods of time.

9.
What is a cause of death for manatees?
Correct Answer
D. All of the Above
Explanation
Manatees face multiple threats that can cause their death. Loss of habitat is a major cause as it leads to a decrease in their food sources and disrupts their migration patterns. Boat collisions are another significant cause of death for manatees, as they often occur in areas where boats and manatees coexist. These collisions can result in severe injuries or fatalities for the manatees. Additionally, cold temperatures can be fatal for manatees, especially when they are exposed to prolonged periods of cold weather. Therefore, all of the above options are causes of death for manatees.
