Biggest Bumblebees of their time, a rare sight in the ever shrinking forests they call home fully terrestrial sponges evolved to serve as lichens in this setting in the absence of competition, only ever thriving on such moist conditions #Bivalvopia

Yet another entry for my speculative proyect #Bivalvopia ,a seeded world of bivalves. on land however bumblebees where the sole inhabitants and had since radiated into multiple taxa #speculativeevolution (Additional Info in a thread below for anyone interested)

Key to their success was the extensive osteoderm cover, allowing to anchor strong muscles on the tail and protecting it from predators,seahorses became thuniform at last and it only took like 100 million years of isolation #Bivalvopia

#bivalvopia today we’ll explore the diversity of bivalves from another side of the branch,starting at 11 millions since seeding and remaining after 150 millions these mollusk saw little change in their body plan or lifestyle yet they are amongst the most diverse….🧵

Malek | FREE PALASTINE 🇵🇸 Of course! In the end It’s a seeded world ,with nothing but Tulips,bumblebees,mussels,scallops and Pygmy seahorses as the faunal cast, this is one of the derived bumblebees, #bivalvopia the name of the proyect is set on a small habitable planet, dominated by water

Various groups of bumblebees lost flight altogether, now nectar was unreliable for such forms instead they opted for sap ,before them a few small specialist and larvae feed on it ,but against a megafaunal arthropod there’s little you can do to stop it #Bivalvopia

To the south they have kept small ,however on the north they became bigger, with a higher biomass the population on that side now isolated from the og gene pool drifted towards bigger sizes and diversified the species they could feed upon #bivalvopia

#Bivalvopia once again we explore the vast biodiversity on this seeded world, circa 100 millions post introduction our man continent is fully split,with the northern part drifting more and more to th e pole,today we’ll discuss one of many groups and how they deal with such…🧵

Now we time skip 100 millions into the future of #bivalvopia bumblebees now dominate most niches on their little continent,pressuring some groups to develop more “out of the box” strategies to survive,meet the nomads of the sea, a group of bees with some notable adaptations…🧵

A bizarre creature beneath the benthos on #bivalvopia Circa 80 millions post introduction of mussels,flaky mussagels are ecosystem engineers ,mixing the soil and allowing water to penetrate deeper as it fills their burrows,made with the help of an specialized shell…

#bivalvopia But the extreme ends of the lineage are in decline,dependent of the warm currents to reproduce and survive,these giants are a rare sight at 100 millions , averaging 80 cms. They are a feast to snail like bivalves and bald bumblebees (staple decomposers at the shores)

#bivalvopia circa 75 millions post introduction of mussels Heaviest of the shell-less bivalves bipeloinae and related families ,are omnivores of the sea floor,at this point in time they thrive in big numbers,leathery skin and vast amounts of mucus discourages predators …..🧵

Because of this lifestyle flight was lost ,what they lack in airborne capabilities they make up with a competent set of physiological tools to live underground and dig efficiently,allowing them to create networks of tunnels in wich they live #bivalvopia #specevo

Circa 20 millions post seeding on #bivalvopia Ancestraly bumblebees created their nests in the leaf litter ,digging tunnels underground and staying there trough the winter , without predators competition became the driving force for the speciation for a few millions 🐝🧵…

#Bivalvopia 5 millions post human extinction Coming from a early diverging group a species rised to feed on an unusual source with the early booms in populations and close proximity that seahorses had to cope with (due to cohabiting only on the innermost branches of algae )🧵

When food blooms ,millions of butterfly jellies gather in numbers and migrate towards open ocean where they’ll find abundant food ,if they manage to not become a snack themselves …. (#bivalvopia 100 MY post seeding)

5 MY since seeding , H.bargibanti underwent adaptative radiation, exploiting bivalves to parasitise on some of their food ,the increased diameter and smoother surface selected for longer broader tails ,adaptations that would later be repurposed for active swimming #bivalvopia
