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.

Puffins are seabirds with colorful beaks living in northern oceans. Learn about puffin species, diving abilities, nesting habits, and diet.
Puffins are charming seabirds known for their colorful beaks and penguin like appearance. These skilled divers spend most of their lives at sea, coming to land only to breed.
Puffins have stocky bodies, short wings, and distinctive colorful beaks. During breeding season, their beaks display vibrant orange, yellow, and blue colors. Adults stand about 10 to 12 inches tall and weigh 14 to 18 ounces. They beat their wings up to 400 times per minute to achieve flight speeds of 55 mph.
Three puffin species exist worldwide. The Atlantic puffin lives along the coasts of the North Atlantic Ocean, from Maine to northern Europe. Iceland hosts the world's largest Atlantic puffin population with an estimated 8 to 10 million birds. They spend 8 to 9 months at sea each year, coming to land only during breeding season from April to August.
Puffins typically dive to depths of 30 to 60 feet but can reach depths exceeding 200 feet when pursuing prey. Special backward facing spines on their tongue and upper palate hold fish in place. They can hold up to 60 small fish crosswise in their beaks. The record belongs to an Atlantic puffin observed carrying 83 sand eels simultaneously.
Burrows can extend 3 feet or more into the ground. The largest colonies can contain hundreds of thousands of birds. Both parents incubate the egg for about 40 days. After hatching, parents feed the chick for approximately 45 days.
Puffins are social birds that nest in large colonies called puffinries. During breeding season, they exhibit elaborate courtship displays. Pairs rub their beaks together in a behavior called billing. They also perform synchronized head movements and cackling calls.
Puffin populations face several threats despite their current stable numbers in many regions. Climate change affects fish populations, forcing puffins to travel farther for food. Overfishing reduces available prey species. Oil spills devastate coastal colonies.
Puffins have inhabited North Atlantic and North Pacific coastlines for millions of years.
Iceland's human settlers historically harvested puffins for food and feathers.
Lighthouse keepers on remote islands often documented puffin behavior for centuries.
Puffin colonies became important sites for early seabird research and banding studies.
Project Puffin began in 1973 as one of the first seabird restoration programs.
Research revealed puffins can dive to 200 feet and hold breath for one minute.
Studies showed puffins mate for life and return to the same burrows annually.
Scientists discovered the colorful beak layers shed completely after breeding.
Research proved puffins beat wings 400 times per minute to achieve 55 mph flight.
Studies found puffin populations indicate ocean health and fish stock conditions.
Puffins became beloved mascots for conservation and tourism in Iceland and coastal regions.
Iceland features puffins prominently in tourism marketing and souvenirs.
Puffin watching tours generate significant ecotourism revenue for coastal communities.
Puffins appear frequently in children's books as charismatic, colorful characters.
Conservation campaigns use puffin appeal to advocate for marine protection.
Before modern fishing practices and climate change began affecting North Atlantic ecosystems, puffin colonies thrived with abundant sand eels and other forage fish. Puffins occupied remote islands in vast numbers, raising chicks on predictable fish supplies.
After decades of warming seas and industrial fishing, some puffin populations have declined significantly. Iceland's population has dropped from 10 million to 8 million. Sand eel populations have crashed in some regions, causing widespread breeding failures. However, restoration programs have successfully reestablished puffins on islands where they had been extirpated, proving recovery is possible with protection.
Puffins can carry up to 60 small fish crosswise in their beaks at one time
The colorful part of a puffin's beak falls off after breeding season, growing back the next year
Puffins beat their wings up to 400 times per minute to stay airborne despite their small size
A group of puffins is called a colony, circus, or puffinry
Iceland is home to over half the world's Atlantic puffin population, about 8 to 10 million birds
Young puffins called pufflings leave their burrows at night and head straight to sea without their parents
Atlantic puffins are vulnerable in some regions due to climate change and overfishing
Warming oceans shift fish populations, forcing puffins to travel farther for food
Puffin breeding success indicates broader ocean ecosystem health
Conservation programs successfully restored puffins to islands where they had disappeared

60 fish in one beak. Backward facing spines hold fish crosswise with a record of 83 at once.
Beaks change seasonally. The colorful outer layers shed after breeding, regrowing each spring.
400 wing beats per minute. Puffins must flap constantly to stay airborne despite small wings.
They crash land regularly. Small wings make landing difficult, causing tumbles near burrows.
Pufflings leave at night. Young puffins head to sea in darkness without parental guidance.
Half the world lives in Iceland. Over 8 million Atlantic puffins breed in Iceland alone.
Puffins live in the cold waters of the North Atlantic and North Pacific oceans. Atlantic puffins inhabit coasts from Maine to northern Europe, with large populations in Iceland. Horned and tufted puffins live in the North Pacific from Alaska to Siberia. They spend most of their lives at sea, coming to land only during breeding season.
