Recently, Oklahoma state wildlife officials sent out a warning. It told people not to be alarmed when visiting a lake.Strange “jelly balls” are in the lake. They are about the size of soccer balls. The jelly balls, the officials said, are alive but not a danger. Their correct name is bryozoans. Some people jokingly call them dragon boogers.Bryozoans are made up of hundreds of separate tiny creatures. Called zooids, they live together. Scientists call bryozoans colonial organisms. There are many types.Each zooid has a mouth surrounded by tiny tentacles. Zooids feed on bacteria and microscopic plants. The tentacles catch bits of food from the water. They move them to the mouth. Zooids do not breathe air and do not have any blood. Bryozoans have an exoskeleton or a hard outer cover. They produce a jelly that holds the zooids together. In winter, when the lake’s water becomes colder, the dragon boogers die. They leave egg-like tiny zooids. These grow into bryozoans the next year. Some zooids leave statoblasts in the lake. Like hatched eggs, they may grow next year.Statoblasts can stick to birds and other animals. This is how zooids can spread to other lakes.
Manager’s Pro Answer: Yes, a country can be fully prepared for an earthquake. Earthquakes have happened many times before. Now, countries know how to prepare for an earthquake. They can build stronger buildings or houses. Also, governments can teach people what to do during an earthquake. They can teach them what emergency items they need to keep.
