Or at the very least it was incomplete.While mammals, birds, reptiles and amphibia are quite easily defined animal classes, there is no animal class &ldquo;fishes&rdquo;. Different ways exist to classify &ldquo;fishes&rdquo;, but at least three animal classes are needed to accommodate the living &ldquo;fishes&rdquo;: cartilaginous fishes, ray-finned bony fishes and lobe-finned fishes. Almost all research on the lymphatic system of fishes had been done on teleost fishes (one of three infraclasses of the ray-finned bony fishes). Teleostei comprise most of the living fishes including the mostly studied <a href="https://en.wikipedia.org/wiki/Zebrafish" target="_blank" rel="noopener noreferrer nofollow">zebrafish (Danio rerio)&nbsp; <svg class="svg-inline--fa fas fa-up-right-from-square fa-2xs" fill="currentColor" aria-hidden="true" role="img" viewBox="0 0 512 512" overflow="visible"><use href="#fas-up-right-from-square"></use></svg></a> . So everything that follows is about this infraclass (and hence might not apply to sharks and sturgeons to name just two non-teleost fishes).</p>
