Swim for my supper
Sea creatures such as the leatherback turtle
will travel thousands of miles in search of
jellyfish. If the food doesn’t come to you,
you have to go and find it!

It's a production line


Many sea creatures produce


hundreds or even thousands of


eggs to ensure some will survive.


Turtles will lay 100 eggs at once,


while a velvet crab may produce


180,000 eggs!


The BIG escape!


If threatened, a pufferfish may


blow itself up with water to


stop it being swallowed by a


predator, but most predators


know to avoid these


highly toxic fish.


The lion's mane
jellyfish is one
of the largest of
all jellyfish.
