Natural History of Jamaican Land Crabs - the Colonisation of Land and Evolution of Brood Care

[@daltonclayton5135]

I am an American Citizen who was born in Jamaica, and immigrated here 33 years ago. I will be 61 on November 20th. All my young years, I pursued Land Crabs with a single-minded obsession, simply because they are delicious. Some were Red, Yellow, White, and somewhat Brown. I also hunted Hermit (Soldier) Crabs for both food and bait for fishing. This Documentary, is absolutely well made. Kudos to the Narrator!!

[@deronsworld5384]

But I never heard he talk about soldier crab nor pimento crap

[@jeremyknott9402]

delicious ......curried

[@Jam-vj4ro]

Nuff respect to everyone I'm a Jamaican and it's positive to see something positive about my country on here my favorite channel

[@daltonclayton5135]

Jam 1, amen to that!!

[@oocollins]

My lawd, every crab mi see drag my mind if I have curry Inna the kitchen.. 😁😁😁😁

[@rudolfdr.diesel3203]

Well, to all your crab eating lovers. I like them too. But I want you to consider: when I first cam to the carribean Islands in 1986, crabs were covering the roads to their thousands. Migrating to the sea to shead theire eggs (= the larvae only grow in the sea). If you catch berried femails (carrying eggs) you kill thousands of larvae / babies. No wonder that the "land crab" population decreased dramatically on carribean islands. In some there are non left, because no young crabs come back from the sea to settle on the beaches. Eat the males... one male can deal with many females, there are not so many males needed -)

[@joshuadaltilia8480]

Great

[@n.o.m1564]

Programs like these should be aired on national tv

[@1979bobhd]

Crabs never cease to amaze me and I have been fascinated with them since I was 4 years old that was 60 yrs ago. Some day in the future after humans have been long gone and the plants reclaim the land I can see crabs being the predominant life form on earth.

[@rudolfdr.diesel3203]

well, this might be possible. The BBC mad a film about it "The future is wild". The crabs appear there.

[@GiuseppeSan]

This is a top-quality documentary. I really love the dedication the team showed in telling the complete evolutionary story of these fascinating creatures.

thanks :-)

Excellent documentary. Fascinating to learn about the land crabs of Jamaica. It also does an excellent job of conveying the dedication of the scientists who made these discoveries.

[@rudolfdr.diesel3203]

many thanks😀

[@chimyshark]

wow this is awesome! I can't believe the amount of patience and work and perseverance that went into finding all these different crab species. I wish I could do this someday.

[@subliminaljester73]

This video is my place of peace

[@FunerealObsession]

We need way more high quality crustacean documentaries. Thank you so much for this masterpiece. On another note, do the snail crabs (sesarma jarvisi I'm assuming) spend most of their adult lives hiding in these snail shells as well? I imagine before mating they are more free roaming but will always return to one they know is filled when it's time to sleep or it's too hot outside.

[@rudolfdr.diesel3203]

many thanks, the Publications you find in www.science-media.de/RD_publ_ns.htm

Beautiful video!i enjoyed watchin n seeing crab condos..lol i don't think ppl understand how important even alil crab is to the ecosystem!i luv learning new things n seeing all the beauty in the world n now seeing part of Jamaica id never thought much up until this video!its more than just a gorgeous beachy island...

Have you tasted land crabs? Specifically cooked in Jamaica or with spices used in Jamaica. Interesting documentary. Thanks for sharing.

[@gladysbennett8188]

I am Hondurian they are so delicious,

[@rudolfdr.diesel3203]

Yes I did. I spent 13 years studiying in Jamaica. Know, every hill, trail and dirt road from the very east to the very west and lots of caves. :-)

[@7gadmuzik935]

Ok so what if I told you that I live in the Manchester parish of Jamaica currently and there are no beaches , rivers or ponds here , no coast lines yet I can carry anyone and show them thousands of these said tree crabs in my area , they as said live in the wild pine trees Some even in the hills from going even to Kendal All age school we use to catch trees crabs🦀 in our lunch breaks ...

[@okurrt5836]

right at 34:26 in an upper axil i saw some fish like things moving, Doctor, will you be kind enough to identify what that is? with my knowledge i can only assume, that they are some amphibian larvae

[@rudolfdr.diesel3203]

These are Frog (Hyla) tadpoles

[@cherrylgentles6847]

This is so interesting- I, an eater of crabs, didn’t know we had such a variety and the reasons for it / This should be a JIS feature or even taught in schools They all look delicious 🤤 except the hermit😀

Another vital reason why we should leave and preserve our cockpit lands😏😕!!!!!

Love the program learned a lot , especially that evolution with creation is bull and don't know why people don't talk about both and not one . . 😁.. and no I don't feel like debating creation over evolution because at some point if one exist so does the other.. but those ghost crabs 🤩🤩🤩🤩🤩

[@rudolfdr.diesel3203]

Evolution vs. Creation: Once a friend watched a caterpillar, the developmental stage of a butterfly. When disturbed, the caterpillar raised his front, blow up and formed the head of a snake as defence. He said “look at this, how could the caterpillar know that he should look like a snake for defence”. By the way, you must have this caterpillars still in Jamaica if the Chinese not jet succeeded to completely destroy the last remaining nature. I agree that if difficult to understand how natural selection could create this and many other amazing creatures, behaviours etc. Even though it may take a long period of time. Evolution works on genes and their variations, some propagate others not. I told my friend: “ There is a simple example - look at the dog breeds. How should a Chow Chow, a golden retriever, a dachshund know to look like a Chow Chow, a golden retriever, a dachshund? Here man did the same thing than natural selection does. Some genes propagate others not and all this from one genome in an extremely short time”.

[@ramchanbeekham8681]

hold on Mr. Narrator..... the white/ blue crab land crab do not like salt water and don't release their eggs in salt water. I used to catch them and from the Caribbean.

[@DavidYogiFolies]

since when pineapple grows on trees???? sorry, but after this huge inaccuracy, how can I believe anything you will say??...

[@insectwildlife37]

He said there relatives not actually pineapples

[@jjboswell5043]

Your inept use of punctuation tells me you're probably not sharp enough to understand the nuance of what he said.

[@paulg3012]

Jamaicans call bromeliads "toad-pine", crab pine might be more accurate.

[@lynnleigha580]

And the reason why he destroyed the crabs burrow?? To see one? What a balloon knot

[@rudolfdr.diesel3203]

thy dig many burrows and you can see them at the edge of a stream. Many of them are empty. 'nough empty burrows to find shelder. The "burrow" for filming, war artificial, made by own hands. If you have questions, I'm happy to answer

[@juttakuller430]

es mag ja sein, dass Englisch die Sprache der Wissenschaft ist. Da man aber die ganze Zeit auch den deutschen Originalton hört, was ich ziemlich nervend finde, hätte man doch einfach auch eine deutsche Tonspur auf die DVD legen können. Aber so viel ist den Bielefeldern der deutsche Kunde und Interessent eben nicht wert.

[@rudolfdr.diesel3203]

Hallo Jutta, es fällt mir schwer, darauf eine zufriedenstellende Antwort zu geben. Schade, dass die kurzen Stellen im Originalton so nerven, doch mit Bielefeld hat das nur am Rande zu tun.

[@wcurtis101]

This was a great documentary. Who would have known that *SPOILER ALERT... ...*snails play such a vital role in the life of land crabs. Thankyou you for sharing this with us.

Crabs have a long history of preying on snails in general too.
