What if you made a manticore out of different animals, but kept the double rows of teeth?

Easy answer, sharks !! I had some manticores concepts waiting in my sketches to be brought here, here is one them

#mangrove manticore !!#the other manticore concepts focus on other aspects tho #siryl #thanks for the recent reblogs btw !! it always surprising to me bc you are one of the very first blog i've ever followed ahah #i've got TONS of suggestions but i made this one first bc i already had the concept mapped out #manticore #shark #sea urchin #urchin #tiger #monster #bestiary #creature design #chimera #ink #the Unknown #953 #aqva 4 #octem 120

Animal of the Day!

Pencil Sea Urchin (Heterocentrotus mamillatus)

(Photo by Scott Atwood)

Conservation Status- Unlisted

Habitat- Coastal Atlantic Ocean; Caribbean Sea

Size (Weight/Length)- 15 cm

Diet- Algae; Coral; Mollusks

Cool Facts- Instead of being sharp and spiny like their Pacific cousins, the pencil sea urchin’s goal is to look as unappetizing as possible. The 10 centimeter long spines are thick and rounded, resulting in it being simply too large for most fish to be able to fit in their mouths. Pencil sea urchins are mostly sedentary after they find a nice growth of algae to feed on. However, these urchins are capable of moving a whopping 90 centimeters a day when they feel like it. These urchins are threatened by a mixture of ocean pollution and over tourism of the reefs they call home. Pencil sea urchins are also popular for aquarists and often find themselves in the illegal pet trade.

Rating- 11/10 (Now if only they could learn how to write.)

we went to the aquarium today. these jellyfish were called "upside down jellyfish", apparently they literally spend life with their bells laying on the sand and their arms wiggling upwards??

I literally hit 300 followers while writing this so here you go: Here is a study I've done on the various sapient species of Splatoon! Drawing them all in their entirety would take too much time, so I've stuck to just some hands. besides, it looks cool.

Quick note: Keep in mind that the art i’ve done for each group is a generalisation, there is an ABSURD amount of variation between different species so if you want to use this knowledge for your own stuff then literally go nuts! There are basically no rules!

Anyway, This is a very long and nerdy post, so strap in.

First we have the Cephalopods. This includes Inklings, Octolings and Nautili. (I made seperate sciencey-art posts for each a while ago). These guys are cold-blooded, have no bones, blue blood and suckers on the end of each finger (except nautili, cause they’re weird.) These suckers are quite strong especially in Octolings, which can use them to cling to walls and even ceilings. Squid also have sucker-teeth, these retractable, chitinous rings inside each sucker that vary in length and sharpness between species.

Inkfish (excluding nautili) have 3 main types of skin cells;

Chromatophores, which allows for colour-changing

Iridophores/Leucophores, which gives the skin an iridescent effect

Photophores (some squid only) which can produce a blue glow.

Instead of bones, they have a unique system of muscles called a hydrostatic skeleton, which uses fluid pressure (in this case, ink) as a support structure. Blood is used too, but mostly ink cause they have so much of it (once again except Nautili, as they have no ink at all). This means that these guys are super bendy, they can stretch and contract their limbs and even turn their heads nearly 270 degrees!

Next we have both Cnidarians and Echinoderms. (I've excluded crustaceans cause idk how to draw them lmao sorry). These groups include jellyfish, anemones, sea slugs, snails and urchins.

Similarly to cephalopods, they’re all also cold-blooded and lack bones, instead having similar hydrostatic system for support with varying strength between each class. For example, Anenomes have super robust supports in their legs thanks to calcified rods in the fluid cavity, however jellyfish are extremely floppy as they have extremely weak hydrostatic muscles.

On a side note, Jellyfish and Anenome are also unique, as many species have cnidocytes in their various arms and tentacles. These are cells that when stressed, will inject a venom that varies in strength from a bee-sting to literally killing you.

Urchins are similar, as each finger is tipped with a brittle spine that can not only inject a weak venom but also break off into your skin, leaving behind nasty shards that cut you up from the inside. Fun.

And then there’s Sea Slugs/Snails which are literally the sweetest little people alive, they have no natural weapons at all apart from their poisonous flesh. They don’t even have teeth at all! They’re just slimy little buddies who love you! However, urchins are immune to their poison as they eat them. Sea Slugs are actually an urchin’s ONLY source of food (they get sick/weak eating anything else), and this has resulted in quite a lot of legal and criminal issues. It’s whole other can of worms.

And finally, fish. Fish are actually the ONLY people in the entire Mollusc Era to have proper bones and red blood, literally everyone else has either an exoskeleton or a hydrostatic system, with either blue blood or none at all. Damn fish and their weird joints.

Cartilaginous fish (sharks, manta rays) have cool, rough skin that’s kinda unpleasant to touch, whereas the most of the remaining species fall under the ray-finned fish (basically everything else) category, and they are covered in shiny scales.

Also eel, there is no hand. Because eel. I’m very funny.

And with that, I have concluded. I’ve done a lot of research on this stuff so if you have any questions at all or if you want me to draw some more diagrams/related artwork, please don’t hesitate to shoot me an ask! I love talking about/drawing this stuff so it’s of no inconvenience!

the best species/background combo in D&D 5e is forest gnome/urchin because forest gnomes can speak with small beasts and urchins get a pet mouse in their starting equipment, so you always have a little friend you can talk to!

Hello! could you draw a Toxel? please

Absolutely! I've wanted to draw it for a while, but always got intimidated. So this was a good challenge!
