This is an image of three different types of crustaceans. Can you identify each of them?

Identification of Crustaceans:

The image displays three distinct types of crustaceans, each with unique morphological features:

1. First Crustacean (Left): This appears to be a copepod. Key features include its relatively small size, prominent antennae, and the presence of egg sacs (oviducts) attached to the abdomen. Copepods are a group of small crustaceans found in nearly all freshwater and saltwater habitats.
2. Second Crustacean (Middle): This is likely a triops, also known as a tadpole shrimp. It is characterized by its shield-like carapace covering the thorax, multiple pairs of legs, and a long, segmented abdomen ending in cerci (tail-like appendages). Triops are ancient crustaceans, often referred to as 'living fossils'.
3. Third Crustacean (Right): This organism is a daphnia, commonly known as a water flea. It is a small planktonic crustacean with a bivalved carapace, a large compound eye, and a distinctly forked or unpaired antennae used for swimming. The visible yellow structures within its translucent body are its eggs or developing embryos.

Answer: The crustaceans shown are a copepod, a triops, and a daphnia.
