About this place
Unpack the Bradypus–Cryptoses–Trichophilus three-way mutualism (Pauli et al., 2014) and inverted ribcage adhesion anatomy.
For kids: Hang upside down with smiling three-toed sloths wearing a living green garden coat of friendly moths and algae!

What to look for
- Cecropia upside-down hammock fork — Bradypus fibrinous visceral adhesions. Centre the open Cecropia crown where sloths thermoregulate in inverted suspension
- Moss-green fur camouflage canopy — Trichophilus welckeri pelage symbiosis. Locate the dappled mid-canopy foliage matching Trichophilus-tinted sloth pelage
- Weekly tree-base moth nursery — Cryptoses choloepi oviposition site. Scan the buttress-root base visited weekly to sustain mutualistic Cryptoses moths

Ask together: Why is moving super slowly in the treetops actually a brilliant hide-and-seek superpower against sharp-eyed eagles?
Field quiz
Kids' question: How can a three-toed sloth hang upside down for hours without its heavy stomach squishing its lungs?
- Built-in stretchy ribbons hold its stomach neatly to its ribs like a seatbelt!
- Sloths breathe through tiny holes in their claws
- Their stomachs float because they eat helium bubbles
Answer
Built-in stretchy ribbons hold its stomach neatly to its ribs like a seatbelt!
Adults' question: Why do three-toed sloths make an energetically costly weekly descent to the forest floor instead of defecating from the canopy (Pauli et al., 2014)?
- To deliver Cryptoses moths to fresh dung so future moth generations fertilize digestible Trichophilus fur algae
- To hunt terrestrial leaf-cutter ant queens for protein
- To sharpen curved claws against volcanic river pebbles
- To cool overheated muscles in subterranean burrows
Answer
To deliver Cryptoses moths to fresh dung so future moth generations fertilize digestible Trichophilus fur algae
