Okay, the user wants me to define 'asternata' in two sentences. First, I need to make sure I understand what 'asternata' refers to. From my knowledge, it's a type of sea urchin commonly found in estuaries. Now, for the first sentence, I should explain its classification and habitat. The second sentence can mention its behavior or appearance. Let me check if that covers both aspects clearly.
The word "asternata" refers to a species of sea urchin found along coastal areas in estuaries, known for its unique, flattened shape and predatory behavior. It belongs to the family Asteracea and is often found in shallow, nutrient-rich waters where it feeds on small marine creatures.
