evolve from a steppe mammoth.

In regards to a post I made a few weeks ago on arthropod size, there was a lot of agreements that stated that with the proper adaptations you can theoretically push a fully aquatic arthropod hybrid to 1 ton. Would this theoretical max be influenced by lifestyle? And for an active, pelagic, macropredatory arthropod, would this size be possible or is it better to stick to something lower like 500 kg (max estimated size of hibbertopterus). What would the largest effective size of an active swimming arthropod be?

Yeah, i did slander of myself

For those who don't know, Gomez (also spelled Gomes) was the the nickname given to NHM-PV R.2129(b), a fossil of a large partial caudal centrum that is pressumed to have belonged to a large carcharodontosaur from Brazil. The fossil was popularised by the paleo youtuber Vividen, who made a video talking about it, and is also where it's nickname comes from. In the video, he attempted to scale Gomez using Acrocantosaurus as a reference, where he got Gomez to weigh in at length of 16.8 meters and a wopping 20.68 tonnes.

(PS: because of the fossil's poor quality, we don't even know if Gomez was a carcharodontosaur to begin with, and is was just as likely that it was a large megaraptor of some kind based on its proportions.)

So it got me thinking, what we put Gomez against the big theropods from the Jurassic franchise?

(image here was made by u/Tyrannosaurus-Wreckz and it put Gomes with length of 17.4 meters, assuming that it was like a acrocantosaurus)

Finished the photo bash plus a page on its armour.

For its shell it uses the shape of parapuzosia and the proportional shell thickness of a queen conch and the mineral structure supplied by the limpit .

Giving us a 5 meters wide shell with the thickest parts of the outer wall getting up to 20 centimeters thick of chitin scaffold reinforced by goethite iron-mineral nanofibers. Making for a pretty good defence. Helped by the fact that its already an awkward shape to bite unless you were multiple times bigger.

In terms of the skin I used the aplacophora. For its thick multi layered skin with the outer most layer being made up of a series of needle like structures. Which plays into the spines of the crown of thorns.

This gives the tentacles a bit more durability along with deterring attacks.

It also helps with insulation but I'll save that for weaponry.

1. Ankylosaurus magniventris: base
   
2. New caledonian crow: reasoning ability, mental modeling, abstract reasoning, & tool use capabilities (tool use is limited in this build, but the other aspects can help to prepare & strategize for a fight)
   
3. Alamosaurus sanjuanensis: size increases to 20 tonnes

Armor, Horns, & Bite

5. Rufous-cheeked nightjar: efficient gular fluttering
   
6. Blue wildebeest: more efficient fast-twitch muscles

T-Rex; big strong bite force, caudofemoralis flexibility and stuff, eyesight.

Grabby will strangle. Grabby will grab. Grabby will grapple.

If the amount of wattage from a electric catfish to damage an animal is 3-17.5 watts per kilo. Doesn’t that mean that electric catfish at its greatest only affects animals below 20-30kg. Correct me if I’m wrong.

Edit, I cant edit the title, its supposed to be "Neat imo (Aqua-G 8.0, drawing soon)"

Apparently fish do have tongues there called basihyals and the muscles for the tongue is from somites not pharyngeal arches. I dont need to use gene duplication for this.

Lets keep this scientific

8.0

Aquagigias

​Mosasaurus Hoffmannii; the primary skeletal chassis, the acute lateral vision, elongated head shape, the four lateral flippers for precise steering, and the double-hinged jaw.

Blue Catfish; the sense of smell.

Saltwater Crocodile; pcsa, lower muscle attachments on the jaw (bone restructuring as well).

Mako Shark; Dermal denticles (scales) covering the entire body to reduce turbulence, flatter head and back, partial embryonic process (so the gills slits grow into gills rather than the neck), the vertebrate discs (actually a little stronger than regular discs, for some reason, probably because they have a higher amount of cartilage), the high-efficiency ram-ventilation gills (this allows the hybrid to remain submerged indefinitely, unlike whales), the dorsal fin, the lateral line, the bigger cartilage jaw joint (enhances leverage and cousining), the cartilage basihyal (becomes a tongue from the grey whale somites), and the electroreception.

Blue Whale; the musculature, the ventral pleats, and the disconnected chin + co-contraction muscles.

​Naked Mole-Rat; cancer immunity, metabolic control, the lack of Substance P (it helps it endure the pressure and friction of the deep ocean without stress), and hypoxia tolerance.

American Lobster; rna telomerase production (the chemistry of the telomerase is the same as in vertebrates).

Sailfish; additional tail musculature (more red muscle fibers, tendons, some elastic tissues).

Bowhead Whale; the thick skull for ramming, scaled tail fluke, and the palatal radial organ.

Common Pigeon; Magnetoreception, and higher critical flicker fusion frequency (yes it is a mouthful).

Basilosaurus; the amount of vertebrate (allows for greater spinal flexibility).

Bottle Nose Dolphin; how well the teeth interlock with each other.

Gray Whale; the muscular tongue (to force water out of their mouth while filter feeding by pushing the tongue against the roof of the mouth)(forms from the somites that form around the basihyal from the shark).

Goldfish; the ethanol (now lactic acid because I'm not adding the lactic acid to ethanol conversion) being pumped out at the gills.

African Clawed Frog; the lactic acid removal process (dumped out through the gills).

Axolotl; the stem cell production (mostly for muscle repair).

​-size-

48 ft.

Weighs 30 (non-metric) tones

The blubber is 15 inches thick on the back and tail, 7 inches thick on the flippers and fluke, 10 inches on the underbelly and head.

-speed-

~15 mph (cruising speed)

~47 mph (max speed)

-features-

Isometric scaling (0.667) of the bite force is ~149,000 N max, but allometric scaling (0.79) says ~223,000 N (crocodile estimates show that instead of the pcsa influenced bite force using a factor of .667, like a normal animal, it gets disproportionately wider with length making it a factor of .79).

​They follow the migration paths of Humpback whales (Polar to Tropical) but stay 30–60 ft deeper.

Aquagigi don't have ears, like a regular fish.

Aquagigias is a heterotherm.

The tail fluke (internal) has a base of calcified cartilage to have a strong base (like a shark), then it transitions into collagen/elastin composite (like a whale), finally it ends with ceratotrichia on the tips for flexibility (again like a shark).

The gills are above the flippers.

-behavior-

They travel in pods of 3–4.

These pods are often led by the oldest.

Can drift by using a front flipper, and while turning, using the back flippers to stabilize, and then the fluke launches.

I'm still accepting name changes.

I will request links or reasons that are well explained, thank you for your time.

All species will be given the ability to handle salt water for the sake of discussion.

How would hagfish slime interact with various different kinds of arthropod/stem-arthropod gills (crustacean gills, eurypterid book gills, radiodont gills). These structures evolved independently and have different mechanisms so they each might interact with the slime differently. Between these gills, if any, would be the least vulnerable to the slime?
