Croc colours and patterns
Somewhat inspired by a recent post by Joschua Knüppe, I feel like it's a good thing to remind people just how diverse colours and patterns in modern crocodilians are. When I see people make art, it often seems to stick to grey or yellowish-brown tones, which is of course not incorrect. But theres a lot of, imo, underappreciated variety still. It's also worth noting beforehand that patterns are most striking in younger individuals and naturally become more muddy the older and larger an animal becomes. But as you will see, even some decently large and old animals may maintain a striking appearance.
Take this alligator for example. Gators tend to be on the darker side, dark greys to black, sometimes countershaded and sometimes pretty consistent. Some individuals, like this one photographed by Gar Luc, still retain clearly visible stripe patterns from when they are younger.

Or take one of my favourite species, the Cuban Crocodile, which can appear almost bright yellow with a dense pattern of leopard spots. Of course like with the gator you can find individuals that are much more drab, with washed out colours, but individuals with clearly defined patterns still exist.

Then there's gharials of course. They can range quite a bit in colouration. They can be brown, especially younger ones and females and I've seen males range in colour from a drab grey to almost a light blue or even something that could be described as metalic black.

Black Caimans are also pretty interesting in my opinion and pretty easy to tell apart from other species once you pay attention to their colour. They are primarily a deep dark black of course, but what sets them apart from spectacled and other caimans is that very fine pattern of thin white stripes across the flanks that creates this beautiful contrast. They can also have patches of brown like the one on the right.

Orinocos also vary a great deal. Tho I know less about them than I wish I did, I know that individuals can range from drab brownish greys to yellow to somewhat earthy browns that almost range into reds.

The next ones a bit of an outlier. There are specific cave dwelling dwarf crocodile populations in western Africa with striking orange colouration. Tho this one is not exactly natural pigmentation to my knowledge and instead the result of the chemicals present in the water they inhabit, brought there by bat guano. Still very pretty animals.

And then there's Paleosuchus, the dwarf caiman which contains two species. Again highly varied. The first image, which I believe is a Schneider's dwarf caiman, shows a very earthy brown. The others, which unless I'm mistaken are Cuvier's dwarf caimans, show colours ranging from dark with a rusty head, black to this still beautifully patterned individual. Of course these variations are also subject to change with age.

While salties aren't exactly known to be the most vibrant, I'd be remissed if I didn't mention this specific one. It's kept in a zoo in Germany and has this almost bizarre colour combination of creamy white underbelly and chocolate brown top which I've never seen in another saltwater crocodile.

Spectacled, Broad-snouted and Yacare caimans I'll give a quick shout out. I think most people are familiar enough with how they look like and while their colours aren't anything special, I still think one should appreciate their patterns of spots and stripes and facial markings.

The last one I wanna highlight is the false gharial, Tomistoma, another one of my favourites. Part of the reason why being its at times beautiful reddish-brown colours.

Falcatamacaris bellua is not, as it may seem at first glance, a fictive trilobite designed by a 6-year old, but a large (~10 cm) arthropod from the Weeks Formation (early Cambrian) notably distinguished by curved pleural spines (giving it its name*), a weakly biomineralized cuticle, and an unwillingness to be classified precisely.
Bonus views of the quick 3D model I made as a drawing reference:

References and notes:
*name which, by the way, is based on an incorrect use of the latin falcatus,-a,-um in its unexplainably inflected form falcatam, which exasperates me disproportionately (name should be Falcatacaris (how did the reviewers not give them shit for that mistake?)) (i am experiencing several taxonomy-related annoyances these days (perhaps i just need something inconsequential on which to take out my anger (anyway))).
Available fossil material of Falcatamacaris only features the dorsal carapace along with limited evidence for 3 cephalic pairs of limbs (but apparently no antennae) (Ortega-Hernández et al. 2015). The walking appendage morphology and arrangement depicted here is therefore only speculative and based on a generalized artiopodan (a broad group including trilobites and friends, within which Falcatamacaris has an uncertain position), after Sein & Selden (2012).
