-'''''Daphnia pulex'',''' although often called water fleas, are freshwater crustaceans closely related to shrimp. Daphnia, the most common microscopic crustacean, can be visible to the naked eye, with lengths ranging from 0.2–5 mm. Their reproduction alternates between asexual and sexual reproduction, with females laying eggs during the warmer season and males only being produced during stressed conditions, such as overcrowding or cold temperatures.
+[Draft]
-Daphnia are metazoan organisms, like nematodes, bristle worms, and tardigrades. Metazoa feeds on algae and bacteria, and algae- and bacteria-consuming protozoa like amoeba, flagellates, and ciliates. Protozoa control the bacterial population and pathogens, cycle nutrients, and improve water clarity. Metazoa keeps protozoa and bacterial populations in check.
+'''''Daphnia pulex''''', commonly known as water fleas, are freshwater crustaceans closely related to shrimp. Though microscopic, Daphnia are among the most visible small crustaceans, ranging in size from 0.2 to 5 mm. Their reproduction alternates between asexual and sexual cycles, with females laying eggs in warmer conditions, while males are produced under stressful circumstances like overcrowding or cold temperatures.
+Daphnia belong to the group of metazoans, which also includes nematodes, bristle worms, and tardigrades. Metazoans feed on algae, bacteria, and protozoa, such as amoebas, flagellates, and ciliates, which help regulate bacterial populations, cycle nutrients, and enhance water clarity. Metazoans play a role in controlling protozoa and bacteria levels.
+===== Physical Characteristic =====
+Daphnia pulex has a characteristic translucent carapace, which allows scientists to observe internal processes such as heart rate, digestion, and reproduction in real-time.
