r/crabs

I’m pretty sure it’s two on top of each other, but I’m not sure. (Also, they are alive)

Doing a field guide for uni and need to try to ID species or at least genus…

Years of evolution and it can't flip itself over basically was the title of it or something

My first ever crab.. I don't know what to name him/her. I will wait til I see their personality.

My dog ​​barked in complaint at night, and when I approached, he was fighting a baby crab. My dog ​​was so afraid of it that I named the crab David, and my dog ​​was Goliath. Just like in the biblical story, the crab won, but with a little help from me, I showed him the way to the light (the sea).

This is also a lesson from nature.

I fell in love with these crabs I seen at a pet store once, but couldn't get them at the time, so now I'm waiting until they come back to this pet store as I was informed they will be getting some soon.

I want to have the cage set up before I get the crab. However, I have only had mammal pets. All this talk about water filters, heaters, humidity etc scares me, but I'm willing to try something new.

Anyone with habitat and care tips for me? There is not much information about these crabs online. ):

Here’s just some baby crabs I found on the beach

At first glance, arrow crabs barely look real. With their tiny triangular bodies and extremely long spider-like legs, they look more like something from another planet than a crab.

These little creatures are commonly found hiding inside crevices, coral formations, sponges, and small caves across the Caribbean and tropical Atlantic — including many reefs and cenotes in Mexico. During the day they usually stay hidden for protection, coming out more actively at night to feed.

Their strange shape actually has a purpose. Their long thin legs help them move through tight spaces in the reef while staying light and agile. It also helps them avoid predators by blending into soft corals, sea rods, and reef structures where they almost look like part of the environment.

Arrow crabs are scavengers and opportunistic hunters. They feed on tiny worms, small crustaceans, leftover food, and sometimes even bristle worms that many reef creatures avoid. Some divers and aquarists even like them because they help clean parts of the reef ecosystem.

One funny thing about them: despite looking fragile and harmless, they can actually be surprisingly territorial with other small crabs.

Definitely one of those tiny macro subjects that makes you stop underwater and think:
“How is this thing even real?” 🌊

This crazy "yeti crab" lives around boiling hot deep-sea hydrothermal vents.

Tengo varios dias encontrandome a estos pequeños en la puerta, mi casa esta cerca de la playa, a veces pienso que es por la piscina, lo extraño es que aparecen muy tarde en la noche o muy temprano en la mañana.

Alguien tiene solucion?

found in galveston bay. he went back in his rock unharmed

Hey fellow Crab lovers 🦀

I appreciate this is a little ODD compared to the usual posts here but given it's still on theme, I hope it will be okay!

We (Odd Dreams Digital) have just released a video game about Crabs & Carcinization called Everything is Crab and we're hoping to spread the word of Crab to fellow enthusiasts!

It's a 2D PixelArt based Animal Evolution Roguelite game where you start off as a little blob each run and evolve into many weird and wonderful creatures while the world around you becomes more crab-like (and yes you can fully become a crab yourself if you choose! 🦀) The game has a deeply layered gameplay around 125+ different types of real world Evolution (some crab, some not).

I'm posting here today as a dev of the game because we just released the game yesterday and would like to share the news of that with people who may have an overlapping interest!

If you're a gamer who loved Spore and/or modern Roguelites, then this might just be your cup of tea!

It's currently available on:

• Steam
• Epic Games Store

Thanks for your time and keep Crabbing on!

P.S. The attached pictures are just some examples of what kind of creature you can create (there's well over a million different combinations you can visually become with a ton of different gameplay playstyles you can lean into)
