The still images link to .avi files (xvid mpeg-4 compression) which
will open if your local system has an assigned helper application, and
the Xvid codec installed.
Mac users, and those with other difficulties, may be best off
downloading the video and playing it with VLC media player.
Fish turns
A tilapia trained to swin through hoops performs a turn through 90 degrees. With the hoops separated by this great of a distance, the turn is obviously not a single maneuver, but rather aseries of small decisions and adjustments. LEARN MORE
Filmed in a 300-gallon aquarium, the images are conspicuously free of flares and reflections.400 frames/second 3.0 MB
Automated fish tracking
An adult tilapia performs a C-start as seen from below.
Superimposed on the negative image is a wire-frame model, part of the
two-dimensional tracking software (written by Ebraheem Fontaine)
that is used to extract kinematical parameters.400 frames/second 3.0 MB
Automated
fruit fly
tracking with Ctrax
Graphical output of the automated tracking program "Ctrax", developed
by the Dickinson group. The trajectory of each individual fly is
recorded, which enables statistical analyisis of their walking ability
in the sloped dishes.

Tethered blue bottle fly Calliphora
latifrons
Housflies have linear dimensions ~five times greater than Drosophila, and 2/3 the wingbeat
frequency. An individual wing weighs approximately 170 micrograms.

Tethered blue bottle fly Calliphora latifrons
The same fly as above, with its wing mass artificially
doubled. Modified flapping kinematics are evident.

Snakefly Take-off
Female snakefly (order Raphidioptera); the takeoff is characteristic of high wing loading.10 000 frames/second 1.5 MB
Hoverfly
In contrast to the snakefly, a hoverfly has relatively low wing loading.

in order to record the vectorial flow field in the plane of the
laser. LEARN

Jumping
spider I
Garden variety jumping spider (Salticidae).
The jump is powered not by mucle, but rather by hydraulic pressure in
the hemolymph (Parry and Brown, "The Jumping Mechanism of Salticid
Spiders" Journal of

(1959) 654.
