The manta ray has a mouth like a sieve, which it uses to filter the sea for microscopic algae and animals, like the copepod.

This parrotfish has developed a safe way of sleeping. At night it envelopes itself in a mucus bubble. This stops predators, like sharks, from smelling it out on the reef.
The tiger shark is one of the most voracious predators on the reef, eating everything from fish and sea snakes to seabirds and turtles. Scientists have also found a whole range of other things in their stomachs including rubber boots, pets, handbags and hubcaps.
Can you see how the tiger shark is adapted to be a top predator?
These big-eyed trevally are extremely fast swimmers. This means that they can escape from bigger predators.
The clownfish has developed a symbiotic relationship with the sea anemone. The sea anemone provides protection to the clownfish, helping it escape predators. The clownfish has developed a special layer on its skin to stop it being stung by the anemone’s tentacles.
In return, the clownfish wards off other fish trying to nibble the sea anemone.
This starfish has a special way of eating coral. It sucks onto the coral and throws up its stomach and special chemicals to dissolve the coral polyps.
The crown of thorns starfish is covered with spines and is also poisonous to protect it from predators.
Some creatures, like this stonefish, camouflage themselves on the reef. They do this to hide from predators and sneak up on prey.
Sea cucumbers are a bit like vacuum cleaners, sucking up the sandy bottom beside the reef and taking out any food, including faeces and dead bits of other animals. They have a defence trick of launching their guts through their anus to scare predators.
This photo is in fact two photos of the same sea cucumber, with the image on the left showing it breathing in through its anus, and the one of the right showing it breathing out.
