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.

Toucans are tropical birds with oversized colorful beaks. Learn about toucan species, beak functions, diet, habitat, and rainforest behavior.
Toucans are tropical birds instantly recognizable by their enormous, colorful beaks. These charismatic birds inhabit the rainforests of Central and South America, where they play important roles in seed dispersal.
The toucan's beak is its most distinctive feature. Toucan beaks can grow up to 8 inches long, sometimes half the length of the bird's entire body. The toco toucan has the largest beak relative to body size of any bird. Studies show toucan beaks can adjust heat loss by up to 400 percent.
Toucans are primarily fruit eaters but maintain an omnivorous diet. They use their long beaks to reach fruit on branches too small to support their weight. Berries and figs make up most of their diet. Their beaks have serrated edges that help grip and peel fruit.
The largest species, the toco toucan, measures up to 25 inches long and weighs about 30 ounces. Its bright orange beak with a black spot at the tip makes it the most recognizable species. Smaller toucanets measure around 11 to 14 inches. Males and females look nearly identical in most species.
Toucans live exclusively in the tropical and subtropical forests of Central and South America. Their range extends from southern Mexico through the Amazon basin to northern Argentina. Different species occupy different forest levels. These birds prefer humid lowland forests but some species live in mountain forests up to 10,000 feet elevation.
Toucans are social birds that live in small flocks of 6 to 12 individuals. They roost together in tree cavities at night, sometimes packing tightly into limited space. During the day, flocks forage together, hopping from branch to branch. Toucans are not strong fliers.
Toucans breed once per year during the rainy season when fruit is most abundant. Females lay 2 to 4 white eggs in tree cavities. Both parents share incubation duties for about 16 to 20 days. Young toucans remain in the nest for 6 to 9 weeks.
Most toucan species currently maintain stable populations, but they face increasing threats. Deforestation destroys their rainforest habitats. The pet trade captures wild toucans despite legal protections. Some species have declining populations due to habitat loss.
Toucans have inhabited Central and South American rainforests for millions of years.
Indigenous Amazonian peoples used toucan feathers and beaks in ceremonial dress.
European explorers brought the first toucans to Europe in the 1500s as exotic curiosities.
Toucan beak function puzzled scientists for centuries before thermal imaging revealed thermoregulation.
The Froot Loops cereal mascot Toucan Sam made toucans recognizable worldwide since 1963.
Research revealed toucan beaks regulate body temperature with up to 400% heat loss variation.
Studies discovered the beak's honeycomb structure makes it lightweight at only 5% of body weight.
Scientists documented toucans tossing food backward into their throats with head jerks.
Research showed toucans are crucial seed dispersers for many rainforest tree species.
Studies found groups of 6 or more toucans squeeze together in single tree cavities at night.
Toucan Sam made toucans instantly recognizable mascots for colorful tropical nature.
Ecotourism in Central and South America features toucan watching as a major attraction.
Toucans symbolize rainforest biodiversity in conservation campaigns worldwide.
The distinctive silhouette appears in logos, art, and design representing tropical regions.
Pet trade demand threatened some populations before regulations limited collection.
Before extensive deforestation, toucans thrived in continuous rainforest canopy throughout Central and South America. Abundant fruit trees supported healthy populations. Toucans dispersed seeds across vast forest landscapes, maintaining the tree diversity they depended on.
After decades of deforestation, toucan habitat has become fragmented. Some species face declining populations as forests shrink. Conservation efforts focus on protecting remaining rainforest corridors. Toucan survival depends on preserving the tropical forests that provide their fruit diet and nesting cavities.

How much do you know? Take this quick quiz to find out!
Beaks are radiators. They adjust heat loss by up to 400 percent like car cooling systems.
Beaks weigh only 5% of body weight. Honeycomb structure makes them lightweight yet strong.
They toss food backward. Quick head jerks flip food into their throats from beak tips.
Groups sleep packed together. Six or more toucans squeeze into single tree cavities at night.
Baby beaks grow after hatching. Toucans are born with small beaks that enlarge over months.
They cannot fly far. Short bursts and glides between trees, not sustained long distance flight.
Toucan beaks help them reach fruit on branches too thin to support their weight. The large surface area also regulates body temperature by releasing or retaining heat. The colorful beaks help toucans recognize their species and attract mates. Despite looking heavy, the beaks are lightweight and hollow.
