It is no surprise to find that most jellyfish
– the stingers we reluctantly meet when we least expect them – while
swimming in the sea on holiday – are predators. Jellyfish are members
of the plankton and most are large. It would be wrong though to
think all predators are large. Some are microscopic, science-fiction
characters with habits that leave vampires and valkyries in the
shade. Some are “smash ’n’ grab” specialists, others are “creep
up ‘n’ swallow” specialists. All are effective and some are so numerous
that they pose a real threat to commercial fisheries by wiping out
whole populations of larval fish or larval shrimp.
The predators shown here are solitary wanderers.
A few predacious species exist as great marauding swarms – sometimes
occupying several square miles of ocean.
