Crab Facts: Claws, Shells & Secret Behaviors
Crabs are crustaceans found on every continent with over 7,000 species. Discover why crabs walk sideways, trade shells, and grow claws stronger than jaws.

Flamingos are pink wading birds with 6 species worldwide. Learn why flamingos are pink, their filter feeding techniques, social behaviors, and wetland habitats.
Flamingos are large wading birds famous for their vibrant pink plumage and distinctive appearance. Six species inhabit tropical and subtropical regions across Africa, Asia, the Americas, and Europe.
Flamingos are not born pink. Chicks have gray or white plumage that gradually turns pink over two to three years. Their distinctive color comes from carotenoid pigments in their food. Flamingos consume algae, diatoms, and small crustaceans like brine shrimp that contain beta carotene and other carotenoids.
Flamingos have specialized beaks perfectly adapted for filter feeding. Their bills curve downward with the upper mandible smaller than the lower, the opposite of most birds. A flamingo's tongue acts as a pump, pushing water through filters up to 20 times per second. This efficient feeding method allows flamingos to extract nutrition from water too shallow for most wading birds.
Flamingos are highly social birds that live in colonies ranging from dozens to over a million individuals. Large groups provide protection from predators through collective vigilance. They perform synchronized group displays including head flagging, wing salutes, and marching formations. These mass displays stimulate breeding readiness across the colony.
Flamingos have long, thin legs adapted for wading in deep water. The backward bending joint visible on their legs is actually their ankle, not their knee. Their necks contain 19 vertebrae, more than most birds, providing exceptional flexibility for feeding at various depths and angles. Their large wings enable strong, direct flight at speeds up to 35 mph.
Both parents build cone shaped mud nests 12 to 20 inches tall that protect eggs from flooding and ground heat. Both parents take turns incubating for 28 to 32 days. Chicks leave nests after 5 to 12 days and join crèches with other young birds. Young flamingos fledge at 70 to 75 days and reach full maturity at 3 to 6 years.
Ancient Romans considered flamingo tongues a delicacy and served them at lavish banquets.
Phoenicians were named for the Greek word for purple red, possibly referencing flamingo colors.
Flamingos have existed for at least 30 million years, outliving many species that are now extinct.
Spanish explorers in the Americas were amazed by vast flamingo colonies in Caribbean salt lakes.
Research found flamingos can stand on one leg with zero muscular effort using a unique locking joint mechanism.
Studies showed flamingo beaks evolved to filter upside down, unique among birds.
Scientists discovered flamingos form lasting friendships that can span decades.
Aerial surveys revealed flamingo flocks can contain over one million individuals.
The pink plastic lawn flamingo became an iconic symbol of American kitsch after its 1957 invention.
Flamingos represent Florida so thoroughly they became the state's official bird after a long campaign.
Alice in Wonderland featured flamingos as croquet mallets, cementing their whimsical image.
Flamingo watching has become significant ecotourism in Africa, South America, and the Caribbean.
Before conservation awareness, flamingo colonies were regularly raided for eggs and feathers. Their habitats were drained for agriculture and salt extraction. Many populations declined as wetlands disappeared across their range.
Protected reserves now safeguard major flamingo colonies. Ecotourism provides economic incentive for conservation. However, climate change and water diversion continue threatening the specialized lake habitats flamingos require. Their iconic pink color has made them conservation ambassadors for wetland ecosystems worldwide.

How much do you know? Take this quick quiz to find out!
Baby flamingos are born white or gray and take up to 3 years to turn fully pink.
Flamingos can only eat with their heads upside down, filtering water through comb like structures.
Both male and female flamingos produce crop milk to feed their chicks, one of few birds that do so.
Flamingos can drink near boiling water from geothermal springs and also survive freezing temperatures.
A flamingo's knees appear to bend backward, but those joints are actually their ankles.
Flamingos have been observed forming same sex pairs that successfully raise adopted chicks together.
Flamingos are pink because of carotenoid pigments in their diet. They eat algae, diatoms, and small crustaceans containing beta carotene. Their digestive systems break down these pigments and deposit them in feathers, skin, and beaks. Brighter colored flamingos indicate better nutrition and health. Chicks are born gray and develop pink coloring as they mature.
