I remember the original True Facts videos. They were funny, a bit informative, but comparatively short. The True Facts videos we get now are delightful masterpieces of both comedy and informative facts, and I look forward to every video that gets released. Thank you so much for all of your hard work, and for your science hippies who help provide you with amazing videos and information

I used to keep a few fiddler crabs with a moon crab(pretty orange, black and purple land crab). One of the male fiddlers once tried to intimidate the moon crab, about five times it's size. He kept waving his claw, get closer, wave again, get closer. He finally got to the top of the tank where the moon crab was and was waving his claw right in his face. XD The moon crab just grabbed him by the claw and tossed him across the tank. The fiddler was fine except for his pride, which he recovered by going over to a female and doing a victory dance despite having lost.

Man the feeling you get from clicking on a new video immediately as it comes up on your screen is so satisfying

@charmh.422

Wow, first time I've heard of sponge and decorator crabs, and that there are crabs that carry anemone pom poms. So much to learn from ZeFrank.

@jonofreedrix

I contributed about 4 seconds of fiddler crab footage to this video at

Knowing that coconut crabs are actually gigantic hermit crabs is a bit life changing for me. My little herbies were some amazing pets and I always wanted bigger and bigger ones. Now I know I can get gigantic ones. Side quest unlocked. Acquire coconut crab.

@DanGamingFan2846

Crabs are pretty fascinating. There are so many different kinds with so many weird and amazing adaptations.The biggest arthropods on land and sea, claws half the size of their bodies, wearing other animals for camouflage or protection. No wonder everything keeps evolving into them.

The ability of invertebrates to regenerate through molting is amazing! I got a tarantula for Christmas when I was nine years old. At the time I got her, she was missing one of her legs- no idea why or how. Over the course of three or four molts, it grew back completely! The first was actually the most impressive: as small and spindly and shriveled as it was, it had grown under a hard exoskeleton of nothing! With each next molt, it grew back a little bigger and stronger, until it was just as good as of the other legs. Super amazing! Especially for a curious nine / ten year old. I had that pet tarantula for eighteen years. Nature is fascinating!

A friend of mine in the navy was stationed on Christmas Island, and woke up covered and surrounded by millions of crabs! Kinda freaked him out!

The perfect transitioning from land crab to coconut crab to hermit crab was excellent. Like, smooth to the point where I was waiting for him to go back to coconut crabs before I realized he had just moved on to hermit crabs.
