Fish and #robots … what could be better!? Recent paper (https://t.co/UDTsR6rUiI) by Carl White @BIERLABS1 has two very useful tables summarizing #swimming robots and their speed, tail beat frequency, and power used to swim. Here the TunabotFlex demonstrates low cost swimming.

Following up yesterday’s tweet from @rthandiackal on our #zebrafish locomotion work, it’s hard to overemphasize how detailed the velocity vector fields are using IR light and small algae as tracer particles. Paper in @J_Exp_Biol (https://t.co/FCsXkLUreg) #swimming #fishsci

More on missing #shark skin denticles! 3D view of the surface of a leopard shark, with color showing height. The blue pits are depressions caused by missing denticles; new denticles are formed and erupt into each gap. More cool images to come! #swimming #fishsci #SharkScience

[georgelauder @georgelauder]

We all know that #sharks replace their teeth, but have you ever seen #skin #denticles being replaced? Our new paper (https://t.co/dzyZLi4Alo) shows denticles emerging from below into gaps at the skin surface in #thresher shark tails. More to come! #swimming #fishsci #SharkScience

Our newly published article in Physical Review Fluids is up now on the journal's website. This research presents how the wavelength of undulating swimmers' kinematics affects their performance. https://t.co/Bax1RqaIV9

For (yesterdays) #WorldTunaDay, the amazing caudal skeleton of the Little Thunny (Euthynnus alletteratus) in 3D. Segmentation courtesy of @kenaley. So happy to be working with the @BIERLABS1 on #tuna #robotics! #fishsci #tuna #locomotion #anatomy #tail

New publication on the 'Flow Physics of COVID-19' now available to all via open access. Excellent work from the team @JohnsHopkins looking at what we do - and perhaps more importantly don't - know about the fluid mechanics of disease spread. https://t.co/Yn9EEQuy7I

Chinese blind cave fish like this one are not your typical fish. Belonging to the genus​ ​Sinocyclocheilus, ​this species is known to inhabit only one underground stream in Tian’e County.​ ​Like many cavefish it has a lack of pigmentation and reduced eyes.

3D fish kinematics as input into computational fluid dynamic models is such a powerful combination: full 3D body motion reconstructed from multiple high-speed camera views. Trout model by @justinwang2011 to welcome @HaiboDong1 to Twitter! #fishsci #swimming #hydrodynamics #CFD

To understand the function of the subterminal lobe of #sharks @FredrikJutfelt, it’s critical to have 3D tail kinematics. View from behind shows tail trailing edge motion. Movie of a bonnethead with @FlammangLab. Also: https://t.co/LCeLkFrIgD. #locomotion #fishsci #swimming

Finlets have complex effects on #tuna swimming: no thrust, but greatly modify the tail flow environment. Simulations of finlet function by @justinwang2011 and the Haibo Dong @UVA flow simulation lab in @royalsociety Interface: https://t.co/hb2eD5wnPH. #fishsci #swimming #CFD

Could tuna inspire the next generation of autonomous underwater vehicles? Researchers at @MCZHarvard and @yalepeabody present data on the morphology, behavior, and function of tunas. https://t.co/eyVLPiVrGb

[georgelauder @georgelauder]

Simple physical modeling provides considerable insight into the function of fish structures, like the amazing lateral keels of #tuna. Here we study the effect of adding keels to a tuna-like robotic propulsive system (see https://t.co/zizGMJZivO) #locomotion #fishsci #swimming

[The Royal Society @royalsociety]

Tuna can migrate thousands of kilometres and remarkably still execute high-speed manoeuvres. The small “finlets” in front of their tails were thought to improve swimming performance. A new study in @RSocPublishing appears to confirm this idea. https://t.co/5dDw52wMR7

[Royal Society Publishing @RSocPublishing]

How do #tuna do the locomotion? Find out in a new computational hydrodynamic analysis of finlet function https://t.co/PfbqZNUrt5 #Interface @UVA @Harvard
