Top 10 Unusual and Amazing Crabs

While on my travels across the internet looking for all kinds of images for my to 10’s I came across one that I couldn’t believe was real. It was a picture of a coconut crab climbing on a bin! Not only was this image real but it seems that I may have underestimated just how amazing the entire crab family is because to be fair there are some rather surprising ones…

These amazing crabs (That are not proper crabs at all, but hermit crabs) are standard bright blue although they can also be orange or red, and the biggest ever recorded measured 18 inches across!!! That is one big crab indeed.

9 – The Yeti Crab

This crab is in fact often called a “Hoff Crab” due to this super strong crustacean’s hairy chest that they comb every day. But these crabs don’t comb their hair to look good, they do it because they’re hungry! Because here is the weird bit, they do in fact grow their food in their hair, trapping bacteria and letting it flourish before picking it out and eating it!

Say hello to Claude because he is officially the Worlds heaviest crab. Weighing in at 15lbs and 15 inches across he is one big crab. But here is the best part: Claude is just a teenager in the World of crabs and is still growing both in size and weight!!!

If there were an award for the cutest crab in the World, this one would win it. Widely accepted to be the hairiest crab in the world, its covered in long, soft, hair that is catches floating food in, although at only 3-5cm in length it doesn’t need much.

5 – The Vampire Crab

So why are they called Vampire crabs? When they are born, they are born with grey eyes, but it is not until adulthood that their eyes become bright red! But at just over 6-10cm wide they are not going to be biting any necks soon.

4 – The Guard Grab

It might be on 5 cm in size, but this crabs entire life is spent defending coral branches from fish, and it does this all day and all night. A true coral guard if ever I saw one.

3 – The Rainbow Swimming Crab.

Regardless of its name, this crab is not all sweetness and lovely coloured shell. With six front triangular teeth and seven acute teeth, four spines on the upper border and super sharp subdial posterior spines it might look lovely but is a walking sea-based tank.

2 – The Candy Crab

This incredibly beautiful crab is very tiny indeed. Measuring just 2cm across in most cases it is very hard to find. They make it even harder to be spotted by pinching off bits of the soft coral it lives in and sticking them onto it’s back!

What is so amazing about this crab is not just its colour, but the fact that it was only discovered last year! This is one of the four new species to be found on its home Island of Palawan in the Philippines.

  2. Common Crab (that’s the common name for the species), which is the most common one you will find close to the beach (with their molt all over the beach) in the northern half of the eastern coast of North America. It’s an edible species, but it remains too small for commercial fishing, rarely grows over 3 inches wide. Obviously not found on the market, you pick them from the wild yourself.

  3. Whoa! These crabs are a colorful lot. You have educated me today, as usual. That first one nearly had me running from the room :/ #’s 9 & 8 made me wonder why I was still looking. Okay, yes I am a scaredy cat :/

  4. Regarding #10. Get me some butter stat!! Mama’s gonna do some work 😀 What a great top 10 list 🙂 I just adore #2…wait..that didn’t sound right….ah hell at my age who cares 🙂

  5. Yow! You’ve done it again!

    I did not know there was such a wide variety of coloured crabs… that one guarding the coral looks more like an octopus on first glance.

    And that huge on on the side of the garbage can gives me the creeping willies!

    Thanks once again for a great post Russell!

  6. These truly are amazing! I never would have guessed. Most of the pictures would give me nightmares (magnified for 50s horror movies)! But I must say some are beautiful (their colors) and the little hairy one makes me think of tribbles! LOL

  7. For me, the giant crab takes the cake (pun definitely intended) because I’ve never seen one that big in all my life! Wow, Russell, (once again) you’ve outdone yourself in showing the originality of God and entertaining and educating the masses, simultaneously. I really admire your creativity, man. God bless.

  8. Amazing… I love the hairy one, but the pink, rainbow coloured and purple are also gorgeous… I must admit to also thinking about the amount of crab meat on the huge one…

  9. Some awesome crabs there, very pretty to lure in the unsuspecting. I will say though, we know how to breed them down here in Tas, check out that crab!!!

  10. I can’t stop thinking about how much crab meat is in that tasmanian giant crab.. is it even edible? Why am thinking about eating it? what’s wrong with me lol. I bet he’s delicious.

  11. Wow what an amazing group of crabs … Thank you for posting these pictures, I had no idea either there were so many interesting crabs swimming around in the oceans.. Take care and stay happy…
