Oliver The Coconut Crab

I’ve certainly considered building an enclosure. There’s no doubt it would be significantly cheaper, and easily tailored to accommodate Oliver’s needs.

My only real qualm is that in order to save money, it’d have to be made of wood. A wooden enclosure of this size, as one would imagine, is ridiculously heavy.

I kept reticulated pythons for years in very large, custom built enclosures made from 1” melamine coated plywood. The enclosures themselves were great, and suited the needs of the snakes perfectly. The issue came when it was time to move. I hadn’t given any forethought to moving the enclosures when I was drawing them up. Disassembling the enclosures was out of the question, as all seams had been completely sealed together with epoxy resin for waterproofing. It was a nightmare.

Today, all of my larger reptiles have been converted from wooden enclosures to PVC. It makes moving and rearranging a breeze. I’ve got an 8’x3’x2’ PVC enclosure that probably weights in around 100 pounds when empty. Easy enough to move around by myself, and virtually effortless with two people. A wooden enclosure of the same dimensions would likely weigh 3 times that. No fun!

All in all, I’m not opposed to building an enclosure, and you’re absolutely right, it would undoubtedly be cheaper. The lessons I’ve learned over the years would certainly pay off when designing a new build. I’ll just have to wait till the day of upgrading draws nearer to see what makes the most sense.

Coconut crabs aren’t for those short of space or resources!

Indeed, plywood is pretty heavy. I would HATE to have to disassemble and move house haha.

However..hehe he...if I may. The big difference wih proper plastic laminate (think counter top style, knife proof) is its completely water tight. I used plywood with glass and punched stainless for most of my large reptiles and amphibian enclosures inbthe last. Even paludariums. The laminate is far thicker than melamine, which scratches easy and I wouldn't trust. Laminate I can make aquariums with. All I have ever used was a healthy dose of silicone in the exposed edges. As the laminate is very very scratch resistant, when I didn't have to move house and take apart the enclosures, I only have to use a razor to scrape out the silicone. Unscrew. Move, screw. Re silicone. Worked a treat!

Granted more work, design etc. Everyone has their ways. But just putting it out here, the key is proper counter top style laminate, not thin melamine. it comes in hundreds o colors and designs. rock, textured, wood grain etc. Enclosures lasted 20+ years before taking a break from the hobby. They probably still live on with the people I gave them all away to.

Just spitballing some ideas

I like the idea of a thicker laminate as a building material. It’d certainly be better/more durable than laminated plywood. I’ll definitely be looking into that as an option!

I should have several years with the current enclosure, but it’s never too early to start thinking about his next upgrade.

Do keep pics coming. I can't say I've even seen someone online keeping them as a pet before, quite interesting!

Hey everyone!

Here’s a bit of a late update on Oliver. I removed him on the 28th of September to get his new weight and take some photos. With this molt he grew to 42 grams, which equates to a 68% increase. I was expecting a reasonable amount of growth, but I wasn’t expecting it to be so substantial!

Besides the expected increase in his leg-span, I was pretty surprised by how much his carapace and left (crusher) claw have bulked out. It makes me really excited to see what kind of size increase he obtains with his next molt.

Speaking of which…

Ollie is down for his second molt! I last observed him on the night of November 6th, and I just noticed he’s created another molting chamber at the bottom of his enclosure. However, this time it’s in a much more centralized spot which will make taking pictures much easier. So, expect some photos of his chamber and molting!

Here are a few pictures I snapped when I took him out for his weigh-in on September 28th. He’s remarkably defensive, and very quick to throw up a threat posture. It was quite a challenge to coax him into the acrylic container for pictures using a chopstick, which he quickly grabbed onto several times and refused to let go of for about 15 minutes each time. He excels at making simple tasks difficult. All said and done the whole process took the better part of an hour. Never a dull moment with a coconut crab I suppose!

Forgot to attach the pics!

 

[Kada]

Amazing! How big til he can start turning your thermometer into oragami?

 

[LucN]

Wow ! This is the first time I see these being kept in captivity. Major props to you for doing the research and designing the right enclosure to cater to all its needs. I am seriously mind blown by this ! Will definitely follow your updates on Oliver. Best of luck in keeping him happy and healthy

That boi is getting big fast!

I think, if he were so inclined, he could probably do that at his current size. His strength is remarkable, even being so small. I’ll be mounting his thermo/hygrometer to the side of the enclosure to try and keep it out of reach! Though, regardless, I’m sure I’ll be going through several in the coming years…

Thank you for the kind words! I’ve spent many years scouring the web for tidbits of information that I could extrapolate to a coconut crabs captive care. This has been a long time coming for me. As I mentioned at the beginning of the thread, there’s only one “care sheet” pertaining to Birgus. It’s pretty much just a large scale trial and error experiment; constantly learning as I go, and adapting his environment based on what he seems to favor and engage with, versus what he tends to shy away from. The name of the game is note taking. Notes, notes and more notes!

He’s definitely growing at a fast rate! I had originally anticipated him molting 4-5 times a year when I received him, though that guess is completely arbitrary and not based on any empirical evidence (again, due to a near complete absence of captive data). However, if he continues on this trajectory, it seems like the hypothesis may end up being accurate.
