About this place
Study Eubalaena australis cyamid callosity photo-ID, mother-calf acoustic crypsis, and Spheniscus–Lama coastal steppe coexistence.
For kids: Explore a wild Patagonian cape where giant whales wear fingerprint bumps, penguins dig desert burrows, and wild llamas watch the waves!
Patagonia Valdés Whales & Steppe · 360° Habitat Camp
What to look for
- Right-whale whispering surf bay — Eubalaena australis cyamid callosities. Centre the shallow surf nursery where Eubalaena pairs practice acoustic crypsis
- Magellanic penguin desert burrows — Spheniscus magellanicus thermal burrows. Locate the coastal shrub steppe excavated by nesting Magellanic penguins
- Wind-swept guanaco steppe bluff — Lama guanicoe sentinel cliff edge. Scan the arid Patagonian terrace grazed by sentinel Lama guanicoe family groups

Ask together: Why would a mother whale and her baby talk in soft quiet whispers right next to a noisy crashing beach wave?
Field quiz
Kids' question: How do scientists recognize hundreds of individual southern right whales returning to Valdés year after year?
- By each whale's one-of-a-kind pattern of bumpy white head patches!
- By painting numbers on their tails
- By counting stripes on their flippers
Answer
By each whale's one-of-a-kind pattern of bumpy white head patches!
Adults' question: Why do nursing southern right whale mothers and calves switch to ultra-low-amplitude 'whisper' calls near Valdés beaches (Nielsen et al., 2019)?
- Surf-zone noise masks quiet calls within ~200 m so offshore killer whales cannot eavesdrop on calf locations
- Warm gulf water absorbs all sound frequencies below ten kilohertz
- Mother whales lose their vocal folds while fasting
- Quiet calls stun schooling anchovies along pebble beaches
Answer
Surf-zone noise masks quiet calls within ~200 m so offshore killer whales cannot eavesdrop on calf locations
