Can you see them now? How have they adapted to survive on the reef?
It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change. Charles Darwin
Speed (jacks) These big-eyed trevally are extremely fast swimmers. This means that they can escape from bigger predators.
Shoaling (silverfish) Sea cucumbers are designed a bit like hoovers, sucking up the sandy bottom and taking out any food. Sea cucumbers have a defence trick of launching their guts out of their anus to scare of predators.
As we saw before, some animals use camouflage to hide from predators and to sneak up on prey, like these stonefish.
Ambush (mantis shrimp) Mantis shrimps hide in small holes in the reef, waiting to ambush their prey. They use their claws to smash or spear small fish.
Venom (triton’s) The crown of thorns starfish is covered with spines and is also poisonous to protect it from predators. This starfish has a special way of eating coral, by sucking onto the coral and throwing up its stomach and special enzymes to dissolve the coral polyps.
Beaks (parrotfish) This parrotfish has a special ‘beak’ to scrape the coral and algae from the reef. Why do you think it is called a parrotfish?
Mucus bubble (parrotfish) This parrotfish has developed a safe way of sleeping. At night it envelopes itself in a mucus bubble. This stops predators smelling it out on the reef.
Hoover (manta ray) Can you see how this manta ray is designed to ‘sieve’ the sea for microscopic algae and animals?
Speed and smell (sharks) How is this tiger shark designed to survive on the reef? How does it get its food?
Symbiosis (anemonefish) This clownfish has developed a symbiotic relationship with the sea anemone. The sea anemone provides protection from predators, and the clownfish wards off other fish who try to eat the anemone.
