I want a tl;dr on this paragraph.

Some scientists think sloths developed their slow-motion lifestyle so they would be less noticeable to predators such as hawks and cats, which rely heavily on their eyesight when hunting. The algae that grows on sloths' fur also helps them avoid predators by letting them blend in with green leaves. They rarely come down from the trees. About once every week, they descend to go to the bathroom, slowly moving about by digging their front claws into the dirt and dragging their bodies. If they are caught by a predator, sloths turn from sluggish to slugger, biting fiercely, hissing, slashing with their claws, and shrieking.

Some scientists believe sloths move slowly to avoid detection by predators that rely on their eyesight while hunting; if attacked, sloths can bite, slash, and shriek. The green algae growing on their fur provides additional camouflage in their home among the trees. Weekly, they come down from the trees to use the bathroom.
