New Crab Discovery links!
An overview of all the freshwater Indian Crabs known:

Ghatiana, Gubernatoriana & Inglethelphusa (Decapoda: Brachyura: Gecarcinucidae)
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight families.
Now we can add at least a dozen more to that list thanks to an Indian team which has
Revisited- with Descriptions of Eleven New Species and an entirely new genus of crab : Sahyadriana.
A group of herpetology and crustacean have been quite busy publishing results of new discoveries that stem back to 2014 and 2018 expeditions to the Western Ghats Mountains During the Monsoon Season.
The researcher' team comprised
Sameer Kumar Pati of Zoological Survey
of India, Western Regional Centre in
Pune, Tejas Thackeray of Thackeray
Wildlife Foundation, Parashuram P
Bajantri of Karnataka forest department
and Gopalkrishna D Hegde.
Currently, 120 species of freshwater crabs under 35 genera and two families are found in India. Kerala is the most species-rich (35 species) state in India followed by Maharashtra (29 species) and Assam (21 species). The Western Ghats of India now includes 17 genera and 58 species of gecarcinucid crabs. A checklist and distribution of Indian freshwater crabs is provided.
According to the researchers, these crabs usually inhabit tiny holes 25-52mm in diameter, and come out during the monsoon season. They were discovered by a group of grad students looking for new snake species. Essentially by accidentally discovering one of the new species during a downpour, while finding shelter in a canyon with small scrub and trees, when they saw the small and beautiful crabs eating worms and small arboreal leaches.
Seeing as leaches are essentially a protein rich food, it is assumed by many, that foods such as bloodworms, black worms, small meal worms and or even larval foods for reptiles would likely provide a fairly well rounded diet for captivity.
Most of these freshwater crabs live near cracks and holes in laterite stone formations, as well as on trees and semisubmerged areas such as slot canyons.
The reproduce by caring live, higher order young, meaning they carry eggs, and then either hatch live, fully formed young, or even withhold the young under the carapace of the mother until able to fend for themselves.
Higher order or secondary spawning crustacean are essentially Miniature versions of their adult body morphology, but unlike most marine crabs, which may spawn thousands of larval young of planktonic size- these crabs all seem to give birth to far fewer young, and also have been documented building nests and tending to their young for several weeks after they emerge as tiny, far less vivid versions of the adults.
Needles to say, this is an exciting development for the Zoological and biological fields, and yet again highlights why we must protect regions like the Ghats mountain of India, to help maintain the amazingly beautiful biodiversity that exists in places like this.
It is yet to be known how widespread thesr crabs may be, but they seem to have evolved as specialists and echo the Taiwanese micro crabs and Indonesian "vampire crab" species. Which have both been successfully kept and readily bred in captivity.

babe wake up new crabs just dropped
Lol
most of India's freshwater crab diversity is concentrated in the Western Ghats and the Eastern Himalayas, I'm from Kerala and have spent a sizeable amount of time in the streams and rivers of the foothills here and the diversity of crustaceans here is immense, I've seen species of cardinioid shrimp which I've still not identified and nocturnal crabs along the various streams of the region. the rainforests and seasonal tropical forests found here are a biodiversity hotspot after all, so such impressive level of biodiversity in such a small area was to be expected. there are also a few arboreal crab species in the travancore region. you can also thank us for your pea puffers.
Yes! I would love to visit that region someday!
YEEEEEEEEESSSS NEW CRAB PATCH!!! LETS GOOOOOOOOOOOOOOOOOO
I wanna go explore the area
Im so excited, my hubs accidentally gave me the idea to make a paludarium and get some vampire crabs, so I've been hunting all the good info 😅 i know you always have the scoop!
Haha well have fun! Aquatic arts seems to have the best selection of any place I've seen. And I think their info care sheets are all spot on , for the various crabs
How interesting thay look so cool thank you for sharing 👍
You've got it!
those little guys are awesome ! I just wish they would try to look less like spiders...
Hah yeah I agree
They do look adorable! So cute and small
And easy to breed all these species usually too!
Goa is a absolutely beautiful area
Totally! And a party center for psychedelic and electronic music haha
@@Fishtory if you know you know 😉🤯

There are Japanese species too, they call them warrior or samurai crabs. They are larger than vampire crabs and occupy small streams, they are territorial, and release miniature versions of themselves.
MyHomeNarure has a bunch of species available and imports from out of the country.
I've heard spiders are related to crabs. These microcrabs are like the link between them. Some spiders carry the eggs until they hatch, some protect the newly hatch young for a while. Cute little buggers! Eventually I want to make a plaudarium. These would probably work well in that type of environment, I'm guessing. Thanks for sharing!
Haha yeah theyre pretty wild.... they occupy literally every possibke biome other than the sky!
Noice! I’m definitely gonna have to get some.
oh my god they're TOO CUTE! Time to find space for another tank lol
Me too haha
Thats pretty cool. They'll never make it here where i am and they'd be blacklisted but those are pretty.
Nz or AU?
@@Fishtory - South Africa ;)
Thank you for sharing.Take care of yourself. I hope you feel better soon.Have a great day.
Thank you kindly
I luuuuuv them, they're so stinkin cute! Sadly no creatures from the tropics for me, cool water tolerant only in the no-name 20L. I _have_ seen a shrimplet tho...👍
Understandable
Crab hype! 🦀 11$ 🦀 I'm most interested in fully aquatic species. Thai micro crabs are cool, but they're really sedentary and reclusive.
I agree with you big time on that
Some cool little critters for sure!
I have a feeling they're the next neocaridinas
Oh these are great additions to your tank! I used to have some red crabs like that. Fun to watch, fine with nano fish. Just make sure they cant climb out cos they will! I once found one two floors down under a radiator. Alive! Thought one had died too, but she molted a left the full exoskeleton just sitting there like some decoy. Nice video, super informative as usual.
Thanks and, yes good tip/heads up for folks haha
for every species discovered, we lose another we've never discovered due to our expansion.
Sadly true
Very intesting that these where found I love that super super cool 🦀
Yeah I may need a terrarium
@@Fishtory dude if I could id hook you up with a brand new 18x 30x exo Terra... It brand new I used it for a baby crested gecko but id hook you up with it if I could 😏
Mornin Alex. Love to see it very cool, have been wanting crabs for a while but Thai micro colouring and size made me feel not worth it, some of these colourful guys look awesome can’t wait
Agreed 100%! And good morning to you
The size is what micro crab lovers are getting them for. Not the color. But they turn bluish when happy.
@@aryah1513 true true
Have they figured out how to successfully breed Thai micro crabs yet?
Last I heard, they got offspring to release, but they ended up dying.
@@Liezuli a few folks have done it now, but it sounds like the huge amount of effort involved is not going to compete with how easy they are to wild collect, sadly.
They are so cute! The only freshwater crabs I’ve seen in the wild here are our Aussie mud crabs in our lake. They are big & bloody ugly! ❤️🇦🇺
Same here :(
Your awesome bro thanks for bringing us new and interesting information
Thank YOU for tuning in my friend
Some of these little guys look pretty cute and you definitely caught my attention with both being nesting species and skipping the larval stage of lower order crabs. These do seem like they'd be a lot easier to acclimate to a captive environment then some other species that, while interesting, can be really challenging to breed ^^'. Speaking of which... I no longer have any saltwater fish so I may attempt to replace my pair of emerald crabs and should really be collecting some nerite snail eggs from my buddies, because those both have larval forms but they start so tiny, I wouldn't be surprised if an amphipod would be more then a match for one of those species. Also, it's clear that at least some of the newly discovered species are amphibious but is there any luck that any are fully aquatic? I may eventually mess around with amphibious terrarium setups but I have none atm, nor do I have any crabs in any setup since I've only seen fiddlers in person and they're super annoying. Cute, but the one time I tried them for around 24hrs I lost three guppies and kept pulling one outta the back of the hob, that was one way to find that they're carnivorous and not truly aquatic lol. It's been a few years though...
Still waiting to hear If any are fully aquatic
@@Fishtory alright, well no rush for me to find out, I'm about to give neo caridina shrimp a second try in maybe a month or two and if they go well this time, now knowing I did a couple key things wrong the first round, I may look into aquatic crabs and if they'd be compatable or will need their own setup. As always, thanks for the in depth info and I'll keep an eye out for updates on this subject ^^
Hey I know you have a million projects and obligations outside of TH-cam as well, BUT I was just learning about sun stressing and UV in regards to assisting plants in metabolizing minerals like iron and other secondary metabolites, which reminded me of what you've talked about with needing "really high light and CO2" for red plants to show their red, and I think it could be an interesting experiment/trial to test whether UV affects the color expression of aquatic plants, and how long you would need it on, whether it penetrates water enough to help with fully submerged plants or just floaters etc.
You don't want too much UV because it's bad for us and it's also bad for the fish eyes, but it would be interesting to see what has what effects.
Yeah there's info on it...and red is often the Aquatic plant's version of sunscreen...it lays onto of the green chlorophyll to protect the chloroplasts from being damaged. :)
So yes... light and or co2 is the main cause of red tones in aquatic plants...and iron only helps to do a similar process in plants living in high nitrate environments. So many people think iron is the trick to red plants and it really isn't any more helpful than other key nutrients in most cases :)
@@Fishtory super interesting! I'll have to hunt for more details, the more I read the more I realize it would be a heck of a project to get a control and whatever variables we can change etc... Maybe if I was using jam jars or something super small it would be manageable, but it's a lot to keep water parameters etc the same between multiple tanks.
Have a great night! Thanks for the informative content, always!
Very nice. I have a close friend who is a doctor in India we could be rich ha ha
Call him up! Haha
@@Fishtory her I just messaged. She loves aquariums and has a few
How long till they’re in our tanks!?
Some have been caught already, so as long as they aren't so specifically localized that collection would be damaging- I'm guessing sometime in 2023 we will see a few of them
This should eventually beef up the crab hobby.
I think so too...hope so
I just started researching freshwater crabs 5 days ago. What are the chances? Thank you.
No problem! I'll show off some vampire morphs soon too!
Are any of these fully aquatic
I don't know yet haha. from what I've been able to read for free, most seem more like fiddler or hermit crabs.
im looking for a temperate climate freshwater crab i can introduce to the the north american continent as an invasive species. im just worried that the wht people will whip up into a frenzy with toxic chemicals in a kill frenzy of saving the environment from bio diversity
they seem to be quite puritanical when it comes to protecting their frozen wastelands from "invasives"
Lol
I honestly don't think we can import these guys and take care of them properly, the main reason being that these crabs are found in forests that experience heavy levels of moisture seasonality, from experiencing some 200 cm of rain in a month to less than 10mm of rain in a month and they are quite threatened in the wild due to the degraded nature of the Western Ghats.
They would need a drip or mist Paludarium setup for sure
@@Fishtory along with that they mainly inhabit lateritic plateaus from what I know, so we would have to mimic that.
🤣🤣🤣thats why you speak the way you do. for attention.
