rom the shallow waters to the depths in all
the oceans of the world, and particularly
in tropical regions, and in the seas a num-
ber of creatures migrate in various ways.
F Some creatures migrate from time to time,
while others do so continuously. One of the
most notable marine migrants is the lobster.

Long Distance Ocean Travelers: Lobsters

Towards the end of autumn, weather conditions in the region in-
habited by the lobster are very changeable. Due to high air pressure,
it becomes very windy. The sky darkens, rain falls, and the tempera-
ture drops. At the same time, the wind creates large waves in the shal-
lows inhabited by lobsters, making the water turbid. This signals the
start of the lobsters’ migration season.
It is not known exactly why lobsters migrate in autumn or how
they time it, but available information points to the influence of envi-
ronmental factors. Sudden temperature changes and intense water
movements may prompt lobsters to change their environment. The
important point is that lobsters notice the climatic changes, under-
stands that these conditions constitute a risk, and take precautions ac-
cordingly. But to take these precautions, they must know what the
best habitat is, and how to get there easily. After making these deci-
sions, they head off in a highly conscious fashion.
