He has also cultivated seaweed for sushi and helped put fish in space, sending 200 swordtails to the space shuttle Endeavour in 1998 to study the effects of weightlessness on the development of their reproductive systems.
These data reveal an accurate predictive downward strike in naïve snakes that coincides with the average future location of the head of the C-starting fish in space and time (Figure 7C, #3) – a result clearly evident in behavior trials (see Movie S2, Clips 16 25).
Studies of reef fish assemblages in space rarely consider the effects of temporal variability on spatial comparisons, and when they do, usually examine timescales of months to years.

With Global Fishing Watch, users can visualize the global fishing fleet in space and time to reveal the intensity of fishing activity around the world.
The test mass (utricular or saccular otolith or statolith) of the fresh-water pond snail, Biomphalaria glabrata [25], marine mollusk, Aplysia californica [24], Xenopus [38], [39], newt [24], and swordtail fish [25] reared in space increased relative to ground-reared controls.
On the other hand, there are many reports that aggregations and the presence of adults reduce the risk of predation and increase the survivorship of juveniles within such an aggregation [25], [26] through better vigilance by more fish in a larger foraging space [27], [28], and the aggressive behavior of adults towards potential predators [29].
Find a group of fish in a relatively contained space, such as a tidepool or small pond.
Thus, it seems likely that the LL may be used by fish to transfer information about position in space, such as direction, distance, and (relative) speed of neighbors in a school.
Variability in fish recruitment has long been linked to the overlap in space and time between larval and juvenile fish and their prey [1].
Recruiting (age 1+) lobsters exhibit a more variable distribution in space; however, for fished (age 2+) lobsters there is greater temporal variation in the probability of encountering lobsters.
