The 20 pages that link to Sea otter, each with the reason it gives.

• PredationBroader topic: Sea otter predation can limit urchins and affect kelp forest structure.

• Trophic cascadeBroader topic: Its predation on urchins can sustain kelp forests along the Pacific coast.

• Keystone speciesBroader topic: By consuming urchins, sea otters can protect kelp forests from intense grazing.

• Kelp forestRelated: By eating urchins, sea otters can limit grazing pressure on kelp.

• MustelidaeBroader topic: This species is a distinctive example of mustelid adaptation to ocean life.

• Marine mammalBroader topic: Sea otters are marine mammals without the blubber insulation common in many others.

• Sea urchinRelated: Sea otter predation can help maintain kelp forests by suppressing urchin grazing.

• CaniformiaBroader topic: Its kelp-forest effects show how a caniform predator can shape an ecosystem.

• Tool use by animalsBroader topic: Its use of stones as anvils or hammers illustrates tool use in marine mammals.

• Mesopredator releaseBroader topic: Sea otter declines can release urchins, illustrating a related cascade rather than mesopredator release itself.

• Guard hairBroader topic: Its guard hairs help maintain the water-resistant condition of the insulating fur.

• KelpRelated: By suppressing sea urchins, sea otters can help protect kelp forests.

• MolluscivoryBroader topic: Its use of stones as tools helps it open hard-shelled mollusks.

• Webbed footBroader topic: Webbing on its hind feet helps it swim and maneuver.

• SeaweedRelated: By controlling urchins, sea otters can limit grazing pressure on kelp.

• OtterBroader topic: It is the most fully marine otter and uses tools to handle prey.

• Fur sealCompared with: Its fur-based insulation is a useful comparison, though it is not a pinniped.

• Red king crabRelated: Sea otters can prey on king crabs and influence coastal crab communities.

• Commander IslandsRelated: Sea otters inhabit coastal waters around the archipelago and influence nearshore ecosystems.

• Sunflower sea starRelated: Sea otters provide another source of urchin predation in ecosystems affected by sunflower sea star loss.
