kelp the sea otters!

SEa Otters can have a parasite

• The parasite is a small thorny-headed worm.
• Sea Otters get the parasite from crabs they eat.

THis is a disaster!

• Most young Sea Otters get the parasite.
• Sadly, this  parasite is fatal to the otters.

Sea otters vs. fisherman

• Sea otters compete with fisherman to get their food because they want the same food.

here's the soltuion

• Fishermen made an otter free zone.
•  Fishermen now fish without competing with the otters.

A sea otter's relationship

• The Sea Otter and Sea Kelp are in a mutualistic symbiotic relationship.
• The relationship could happen if there was a overpopulation of sea urchins.

here's the benefits

• The Sea Kelp use the Sea Otter to eat the sea urchins.
• The Sea Otter use the Sea Kelp as an anchor, when they sleep.

Commensalism

• Sea Otter have a relationship with the fish in the kelp forest.
• But only one benefits, the other is not helped.
• If there was a migration of sea urchins, this could happen.

who benefits?

• Sea Otters eat sea urchins that kill many kelp forest.
• No forest means no home for the fish.
• The Sea Otters are not harmed nor helped, so the fish benefit.

Parasitism

• Sea Otters can receive a deadly brain disease.
• This disease is called Toxoplasma gondii, and it is in the sea now!

ouch, that hurts!

• Sea Otters get the parasite from Sea Lions or Seals.
• The parasite gets somewhere to live.
• The host get a fever, muscle aches,cyst ,and headaches.

Adaptations

• The Sea Otters have webbed feet, and fur that sheds water.
• These adaptations help them survive in the sea.

what caused this adaptation?

• With these adaptions the Sea Otter can swim faster and escape predators.

where are these adaptions from?

• These adaptions come from the Sea Otter's ancestors.

let's spill information about oil

• Oil spills are some thing that effects the Sea Otters environment.
• The Sea Kelp survive because they have mucus on them.
• The environment will go through secondary succession to recover.

let's swim back to health

• The envioment can also be effected by the biodiverty.
• If too many animals die it could be hard for the ecosystem to bounce back.

How do they survive

• Some animals may die, but new ones may move in.
• Sea kelp survived the oil spill, so animals still have a habitat.

sea otter and Human

• Humans fish for food, retreve oil, and we do sports out in the ocean.

Go splash away!

• Humans have caused major damage to the ecosystem by oil spills.
• Many Sea Otters die from oil spills.

Let's spread awareness, not oil

• Sea Otter groom most of the time, so they eat the oil
• Eating the oil can be fatal to the otters sometimes.

LET'S SEA HOW YOU CAN HELP!

• You can help by funding the technology, that helps prevent oil spills and researching how to caputre leaked oil.
