拉蒂迈鱼（矛尾鱼） / Latimeria (coelacanth)

My fleshy fins help investigate your deep family history—but lungfishes win the closest-living-fish-relative contest!
我肉质的鳍有助探索你遥远的家史——不过，最近的现生鱼类亲戚奖，要颁给肺鱼！

Research context
Living coelacanths preserve a distinct lobe-finned-fish branch. Their fins and genomes help reconstruct sarcopterygian evolution; lungfishes, rather than coelacanths, are the closest living fish relatives of tetrapods.
