At the Fisheries Blog, we’re starting a new series of posts, once a month, where we bring back “oldie but goodie” posts from our now extensive archive. Rest assured, these “repeat spawner” posts, smell a whole lot better than that leftover fish you found in the fridge from two weeks ago!

Learn more about seven fish species that represent a lineage over 150 million years old!
