Both belong to same class Crustacea , both have 2 pairs of antanae .
no
Yes. Some barnacles are quite tasty. Acorn barnacles are similar, in taste, to tiny oysters. Gooseneck barnacles are also quite edible, except, of course, for the shell and the thick covering on the neck.
Barnacles are crustaceans, and therefore more closely related to crabs than to mollusks like limpets. The apparent similar morphology of barnacles and limpets is a result of convergent evolution. It does not necessarily require DNA (i.e., similar genotype) in order to produce similar phenotype (physical characteristics).
Since crabs and barnacles belong to the same evolutionary lineage, one would expect their DNA to be more similar. However, convergent evolution could result in homoplasies that would cause a barnacle to have DNA more similar to that of a limpet than a crab.
Barnacles are crustaceans( a type of arthropods)
No they are not
Barnacles and limpets are similar in that both are marine organisms that exhibit a hard, protective shell structure. They are both sessile, meaning they attach themselves to surfaces, such as rocks or the hulls of ships, and remain in one place throughout their adult life. Additionally, both species are filter feeders, obtaining nutrients from the water around them. Despite these similarities, they belong to different taxonomic groups, with barnacles being crustaceans and limpets being mollusks.
commensalism
Yes, "as rough as the barnacles" is a simile. It compares the roughness of something to the rough texture of barnacles using the word "as."
Grunion fish primarily feed on small crustaceans, such as amphipods and copepods, as well as marine worms and small mollusks. They have a specialized diet that includes planktonic organisms and small invertebrates found in the sandy intertidal zone where they spawn.
They are tiny fish.
