Symbiotic Relationships:
Lion and Zebra
The lion hunts and kills the zebra for its
food.
Whales and Barnacles
Barnacles create home sites by attaching
themselves to whales.
Bed Bugs and Human
Bed bugs will bite and feed off a human up
to 500 times in one night. This causes
small red bumps and itchiness to the
human.
Mantis and Bee
The mantis captures a bee and eats it for
nourishment.
Algae and Fungi (Lichen)
Algae and fungi can live together, forming
lichen. The algae produce carbohydrates
through photosynthesis, providing nutrients
to both the algae and the fungi. The fungi
provide moisture for the algae.
Birds and Army Ants
Some birds follow army ant raids on forest
floors. When the army ant colony travels
along the forest floor, it stirs up numerous
flying insects. As the insects flee from the
army ants, the birds following the ants
catch the insects.
Spider Crab and Algae
Spider crabs live in shallow areas of the
ocean floor. Greenish-brown algae lives on
the crab’s back, helping the crabs blend in
with their environment, which makes them
less noticeable to predators. The algae are
provided with a good place to live while the
crab receives camouflage.
Lizard and Insect
A lizard captures insects for its food.
Man-of-War Fish and Portuguese Man of
War Jellyfish
The man-of-war fish lives amongst the
Portuguese man-of-war jellyfish and are
provided protection from their predators.
Goby Fish and Sea Urchins
The goby fish live amongst the sea urchins
and are provided protection from their
predators.
Cow and Grass
A cow munches on the grass in a field for
its food.
Bird Mites and Humans
Bird mites might happen upon a human
when trying to find a new bird to feast on.
Instead, it eats the blood of the human,
causing the human to develop irritating,
itchy bumps.
Braconid Wasp and Tomato Hornworm
Larva
This wasp lays its eggs inside the
hornworm. As they hatch, they eat their
way out, killing the hornworm in the
process.
Ostrich and Gazelle
Ostriches and gazelles feed next to each
other. They both watch for predators and
alert each other to danger. Because the
visual abilities of the two species are
different, they each can identify threats that
the other animal would not see as readily.
Honey Guide Bird and Badger
Honey guide birds alert and direct badgers
to beehives. The badgers then expose the
hives and feed on the honey first. Then,
the honey guide birds eat.
Braconid Wasp and Tomato Hornworm
Larva
This wasp lays its eggs inside the
hornworm. As they hatch, they eat their
way out, killing the hornworm in the
process.
Clownfish and Sea Anemone
The clownfish lives within the tentacles of
the sea anemone. This provides protection
to the clownfish and the clownfish also
feeds on the food scraps of the sea
anemone.
Deer and Tick
Ticks feed on deer blood, causing irritation
to the deer and potentially giving it various
diseases such as Lyme disease.
Tapeworm and Dog
The tapeworm enters the dog when the
dog eats feces containing tapeworm
larvae. The tapeworm attaches to the dog’s
stomach and feeds off of the dog’s
nutrients. This often causes harm to the
dog.
Wolf and Caribou
The wolf hunts and kills the caribou for its
food.
Pearl Fish and Sea Cucumber
The pearl fish spends its day in the
intestines of the sea cucumber and
emerges at night to feed on small
crustaceans. This does not appear to harm
the sea cucumber.
