the fins.
The main difference between lobe-finned fish and ray-finned fish lies in their fin structure. Lobe-finned fish have fleshy, lobed fins supported by a bony structure, while ray-finned fish have fins supported by bony rays. Additionally, lobe-finned fish are believed to have given rise to tetrapods, including amphibians, reptiles, birds, and mammals.
They are a tropical ray-finned fish.

The Actinopterygii, or ray-finned fishes, constitute a class or subclass of the bony fishes. The ray-finned fishes are so called because they possess lepidotrichia or "fin rays", their fins being webs of skin supported by bony or horny spines "rays", as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii which also, however, possess lepidotrichia. These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton.
No, they are jawless fish.
hagfish eat dead fish, including whale carcasses
they stick theyre penis into the female finned fish
Hagfish and lampreys.
lobe-finned fish
Oh, dude, you're like so close but not quite there. The sturgeon fish is actually a cartilaginous fish, not a lobe-finned fish. So, like, they're kind of distant cousins in the fish family tree, but not quite the same. Keep swimming in that sea of knowledge, my friend!
Perch are lobe-finned. The fins on Perch fish are fairly rounded and distinct for this species of fish in the wild.
The three vertebrate classes of fish are: Agnatha (jawless fish without scales, e.g. lampreys and hagfish)Chondrichthyes (sharks and rays, which have skeletons of cartilage rather than bone)Osteichthyes (all the bony fish e.g. tuna, trout, whiting, etc.)
