of fish

A pufferfish sucks

in water to swell

its body.

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.
