Jawless fish are a fascinating and unusual group of fish. Most jawless fish lack any type of jaw, meaning they eat by sucking food in through their mouth like a straw. Jawless fish are found all over the world and can be found in both fresh and salt water. They range in size from a few inches to more than six feet long. In this blog post, we will explore what makes jawless fish so unique and interesting, as well as some of the amazing things you can do with them in your aquarium.
What are jawless fish?
Jawless fish are a group of fish that don’t have the external jawbone that other fish do. They’re classified in two main groups: cartilaginous fish and osteichthyes. Cartilaginous fish include rays, skates, and sharks, while osteichthyes include bony fish like salmon and trout. Jawless fish have evolved from cartilaginous ancestors, so they share many of the same features. Some jawless fish also have some additional features that set them apart from other fish. For example, some jawless fishes have a second mouth on the underside of their head that they use to eat small prey or to suck up water to wet their gills.
