Turtles are mighty animals!
Emys orbicularis | Sardegna | March 2020
They are so strong to survive the Cretaceous–Paleogene extinction, that one of the dinosaurs. Nevertheless many turtle species risk not being able to overcome the Anthropocene. Sea turtles swim in a plastic sea, between fishermen nets and hooks. Freshwater turtles must survive the destruction of their habitat and the introduction of alien species. Tortoises become old only if they do not end up in some private garden as a pet, or crushed by a car. In short, homo sapiens represents a danger for every living species of this planet, including the strongest!

Competition
Phoenicopterus ruber | Reserva de la biosfera Ría Celestún, México | November 2018
Flamingos are very social birds; they live in colonies whose population can number in the thousands. These large colonies are believed to serve three purposes for the flamingos: avoiding predators, maximizing food intake, and using scarcely suitable nesting sites more efficiently. Nevertheless it is not difficult to see two of them fight to contend a partner or some food, and it is precisely on these occasions that they "swell" to look bigger!

Phoenicopterus Ruber
How do flamingos eat?
Phoenicopterus ruber | Ría Celestún, Yucatán, Mexico | November 2018
Flamingos filter-feed on brine shrimp and blue-green algae as well as larva, small insects, mollusks and crustaceans making them omnivores. Their bills are specially adapted to separate mud and silt from the food they eat, and are uniquely used upside-down. The filtering of food items is assisted by hairy structures called lamellae, which line the mandibles, and the large, rough-surfaced tongue.
Mexican crocodile
Crocodylus moreletii | Río Lagartos, Mexico | November 2018
Rio Lagartos is a nature reserve in northern Yucatan. The name comes from the Spanish colonizers, mistaken both of the words Rio and Lagartos: in fact it is a huge estuary (ría in Spanish), not a river (rio), and the "lizards" that live there are not alligators (lagartos), but crocodiles.
The Mexican crocodile (Crocodylus moreletii) is distinguished from alligators by teeth. In fact, it has a perfectly aligned teeth. The fourth tooth on the lower jaw is visible when the mouth is closed because it is slightly larger than the rest of its teeth.
