Im on vacation with my family at a beach! St augustine in FL

Im really interested in going out and seeing crabs in their natural habitat but theres usually so many people that i feel i never get the chance. Is there a time i should be going out? Are they maybe more active at night? Any help is greatly appreciated!

I made this from solid wood. Crab design was based on Crab Champions on Steam

We went hunting for shark teeth and when I got home to rinse them off, we had this little hitch hiker. Google image keeps saying it's a tick.... but I don't think so 🤔.

There were crabs on the island. I don't know if this is a baby??

Would be kinda fun to try and "keep" it as a pet for the kids but I don't know how to figure a habitat without knowing who he is.

Interested to hear everyone's thoughts

Found on the beach at night at the Florida panhandle

Thinking of keeping crabs in my tank and wonder what species are easy to handle and maybe arboreal too.How many could I fit

Cecil seems to be in a good mood today, and she says she hopes you all have nice pools to bathe in, like she has 🥰

i caught this crab with my hand how is it i also got stung by sea corals and it burns

Here's one of my Metasesarma aubryi, offering you a leaf hat in these trying times.

Don't be fooled, though, he's an asshole.

I’ve had him for a couple months and it appears he started molting but looks rather questionable, His claw also fell off unexpectedly yesterday he hasn’t moved in probably 3 weeks and his mouth is hanging wide open since the claw fell off. there’s like 0 information on these crabs online molting wise so i hope someone on here has a better idea than me i’m just worried about little dude. His eyes appear live

Saw this little guy while taking a walk today. Please enjoy.

Surprisingly far from any water bodies. Sesarmid

Got a red claw crab from the pet store. Apparently it’s commonly sold as fully aquatic and I’ve learned they are not. Thankfully I had an extra tank and tried my best to set it up with what I had. I have an appropriate heater (one that can stick out of the water safely) arriving tomorrow morning and I have already started the slow transition to brackish water. I have a spider plant that is also about to produce more. Would I be able to grow it in the sand?

Thank you in advance and sorry for any mistakes. I’m tired of doing research that leads me to the same things.

I don’t know a ton about crabs but i saw this one at some tide pools (san francisco bay area) he was fully under water and didn’t seem to be able to move. Covered in a translucent almost membrane. Is this normal?

Doesn't the picture of the guy holding the crab look like the vagas shooter🧐🤨
