Description Shovelnoses are big (to 3 meters long), fresh water fish what swimwalks on the bottom of Eurasiafricans rivers and lakes 120 millions years in the future. It hunts on creatures buried in mud (mainly crustaceans and mollusks), which it detects using electro receptors in its large shovel like upper lip.
Shovelnoses are one of the spiderfish species and are descendants of Melanochromis . Of course they are cognate to land Octodactylopods. Spiderfishes are cichlids very specialized to live on the bottom of water basins. “Fingers” in their pelvic fins are transformed into eight spider like legs, what they use to walk , what is their primary propulsion. They have no gas bladder and they can’t really swim on long distances. They swim like other fishes only when they must quickly speed up. Of course like all their ancestors, Malawi lake cichlids, spiderfishes are mouth brooders.

When Africa was teared apart in the rift valley, great African lakes merged with Indian Ocean. Most endemic cichlids died off, but some types accommodated to sea water and transformed into sea fishes. Some of them recolonised rivers after millions years . Spiderfishes primary evolved in fast streams, where they developed their finger – limbs. But there quickly appeared species accommodated also to rivers and lakes. Like shovelnoses. And also some species step out of water and colonized lands, turning into Octodactylopods. Only non tetrapods land vertebrates.

What kind of vocalizations do octodactylopods make ?

Great idea. Inspired by gurnards [link] I take it?

I did something similar not too long ago: [link]

Yes, but I didn't remembered what fish exacly had this type of toe limbs (i see these gurnards have rather finger limbs than toe limbs) and what was its name. I remembered only that there is some kind of fish what had simmilar structure. So thanks for finding it.

But this particular species of spiderfish is based mostly on sturgeon. There is also some characteristics of today living cichlids. But it is like in all my spiderfishes, what are cichlid descendants.

It is failed project of common earwig descendant. It behaves like big roaches today and lives in forest bedding.

I think it is just VERY HARD to project future insects. They are just so amazingly big and diverse group that almost ALL what human can invent, already exist or existed somewhere on Earth and very often is in fact even more eerie than on future drawing. Even now, when searching in internet what is english name for earwig I accidently found earwig species what perfectly fit to size and description of this species on sketch above, but looks even more monstrous (Labidura herculeana).

Only insect group what I designed and I am happy with this design are descendant of crickets with maxillary palps transformed into big, scorpion like claws.

Well, I can easily understand the problem with creating future speculative insects, to even remotely keep check over all the current forms of a class that covers pretty much all animal diversity on Earth is far easier said than done. I've personally just recently stumbled over the existence of organisms like mantis flies, scorpion flies and trilobite beetles
I really like your extraterrestrial "psuedomantis" concept, it seems plausible that crickets would in absence of competition diverge into large predatory forms similar to mantids, among others.
