Fish evolution
The scientific definition of fish is complex and can be a little confusing. Here is a much simplified definition. Fish are: Chordates, they have a backbone or notochord (cartilaginous support). Live almost entirely in water. Have apparatus to extract oxygen from water (gills). Have appendages without digits (fins). Are generally ectothermic.Steel toes shoes have come a long way from their humble beginnings as practical safety footwear. Today, they are not only a vital piece of protective equipment but also a fashion statement. In this article, we’ll take a closer look at the h...The Great Fish Market, painted by Jan Brueghel the Elder. Fishing is a prehistoric practice dating back at least 70,000 years. Since the 16th century, fishing vessels have been able to cross oceans in pursuit of fish, and since the 19th century it has been possible to use larger vessels and in some cases process the fish on board.Fish are normally caught in the wild.
