- Do you ever feel like your fish are trying to tell you something? Like your Skunk Cleaner Shrimp is just waiting for your hand to get back into the reef tank so it can ride your hand around the tank? It turns out, at least in the case of cleaner shrimp, they might be sending you signals!
A huge thank you to Dr. Eleanor Caves for providing all the shrimp footage. She studies primarily vision, behavioral ecology, and evolution. If that sounds interesting, I encourage you to check out her research at her website - eleanorcaves.w...
Cleaner shrimp, depending on the species, have different ways of advertising that they're helpers and not food. Skunk Cleaner Shrimp wave their bright white arms back and forth, while others like the Pedersons Shrimp wave their long white antenna around. In both cases, it's a signal to the fish that they're open for business and willing to rid their client's skin of parasites and dead tissue.

Mutual visual signalling between the cleaner shrimp Ancylomenes pedersoni and its client fish

Abstract
Cleaner shrimp and their reef fish clients are an interspecific mutualistic interaction that is thought to be mediated by signals, and a useful system for studying the dynamics of interspecific signalling. To demonstrate signalling, one must show that purported signals at minimum (a) result in a consistent state change in the receiver and (b) contain reliable information about the sender's intrinsic state or future behaviour. Additionally, signals must be perceptible by receivers. Here, we document fundamental attributes of the signalling system between the cleaner shrimp Ancylomenes pedersoni and its clients. First, we use sequential analysis of in situ behavioural interactions to show that cleaner antenna whipping reliably predicts subsequent cleaning. If shrimp do not signal via antenna whipping, clients triple their likelihood of being cleaned by adopting darker coloration over a matter of seconds, consistent with dark colour change signalling that clients want cleaning. Using experimental manipulations, we found that visual stimuli are sufficient to elicit antenna whipping, and that shrimp are more likely to ‘clean' dark than light visual stimuli. Lastly, we show that antenna whipping and colour change are perceptible when accounting for the intended receiver's visual acuity and spectral sensitivity, which differ markedly between cleaners and clients. Our results show that signalling by both cleaners and clients can initiate and mediate their mutualistic interaction.

What a fascinating world we live in.
I agree!
The black tang in the background is having the time of his life lol
5:50 the fish attenae killed me lol
I added a cleaner shrimp yesterday, he seems to have picked out a spot for his cleaning station, but the fish don't seem to be aware. Whenever they get close, he gets all excited, swaying back and fourth, but the fish don't stop for a cleaning and swim off. I wouldn't have thought shrimp were capable of displaying disappointment, but there it is!
I imagine the little shrimp are like the one from finding Nemo and speak French like Ooh, la mer. Bon.
This video deserves more views. It's very fascinating
I don't SEE them as boring i SEE them as goofy and entretaining to watch
Really enjoyed this video. I now know more about one of my tanks inhabitants. Thanks
Just got back into the hobby and this is EXACTLY what I was hoping I would find!
Super cool. I’ve seen my fish line up and the blood shrimp clean them one at a time. Happens about once a week. It’s like a traffic jam in the tank lol Thanks for sharing. The videos really bring the papers to life.
That would be really neat to watch in the tank. I should pick up a couple skunk cleaner shrimp perhaps!
So appreciate your information and ease of understanding !!
Fascinating! How come my 2 skunk cleaner shrimp I owned never cleaned my fish? I have had them in a 36 gallon with small fish like clowns, damsels ect.
Loved this video! You have a articulate and enthusiastic way of getting information across, I had fun learning more about cleaner shrimp communication :D
I’m glad it was interesting! Sometimes I worry that these science videos are dry but I think it’s interesting science.
Thanks Reefman, I have always enjoyed your video.
Did you see those fish tentacles going at the end lol
So Nemo was accurate. Interesting
About vision I don’t know they hide from me scare to death even when I’m far away
I’m wondering if peppermint shrimp are also a form of cleaner shrimp because my green spotted puffer has let him to survive and he’s always sitting next to him in the fish tank. Are peppermint shrimp cleaner fish?
I suspect they might have cleaning as a side-gig. Whenever I put my hand in, my peppermint zips out and starts crawling around on my hand.
@@fireaza OK great that explains it!
I love your videos
What kind of fish is that at 5:20 ?
"Sorry for the Latin" - noooooo
Thank you for the Latin :3
Hypotheses you say. What was their 'IV, DV, or Null'. Sorry charts & graphs, has nothing whatsoever, to do with the Scientific Method. What you are proposing is Conjecture, presuppositions & speculation, akin to a Pseudo-Science.
You're literally a flat-earther
nice vid, just found you......
