What these animals do -- and there's many others, these are just three of them -- is they make adhesives, they stick to each other, they stick to the rocks and they build communities, and by doing this, there's a lot of survival advantages they get.
Estes animais — e muitos outros,  estes são apenas três — fabricam colas, colam-se uns aos outros, colam-se às rochas e criam comunidades. Ao fazerem isso, obtêm muitas vantagens de sobrevivência.
