To determine whether lobsters and sardines have scales, you can follow these steps:

1. Research each marine creature separately: Gather information about the physical characteristics and anatomy of both lobsters and sardines. These details can usually be found in reputable marine biology or zoology resources such as books, scientific journals, or reliable websites.

2. Focus on their skin: Pay attention to the outer layer of their bodies, which is where scales are typically located in fish and other aquatic animals.

3. Lobsters: Lobsters belong to a group of species called decapods, which are known for having a hard exoskeleton made of chitin. While they possess a rigid protective shell, they do not have true scales. Instead, lobsters have small, rigid, oval-shaped structures called "setae" on their exoskeleton. These structures assist in sensing their environment and do not function as scales.

4. Sardines: Sardines are a type of fish and, unlike lobsters, they do have scales. Fish scales serve as a form of protection and aid in locomotion by providing a streamlined exterior. Sardines have small, thin, overlapping scales covering their body, which are typically silver and shiny.

In conclusion, lobsters do not have scales, but sardines do.
