What is a brachiopod.

Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell.Otherwise, the Associate Editor (AE) or Managing Editor (ME) – basically, whoever is handling your paper – is happy to look at the minor revisions and give the clearance (acceptance decision) themselves.
