Close-up portrait of an Harlequin filefish (Oxymonacanthus longirostris). This species is dependant on Acropora corals for its food which makes it highly vulnerable to extinction with the destruction of coral reefs by pollution and climate change amongst other factors.

For once, it’s not about one animal but several… each of these coral colonies is forming a pretty healthy coral reef. Unfortunately, if we don’t take urgent measures to stop climate change, pollution and other consequences of human activities, these will soon be a blast from the past…

Here is one of the smallest turtle species, the spotted turtle (Clemmys guttata) from the eastern half of USA. It is endangered by loss of habitat and other kinds of disturbances such as pollution of waterways. It is protected by law but its populations are still declining.

White sturgeons (Acipenser transmontanus) are smaller than many other sturgeons but have been overexploited by the caviar industry. Luckily, they are still numerous in the wild and now farmed for caviar which allows to better protect wild ones despite of pollution and hydroelectric schemes.
