If you are wondering if there are any alligators in Canada, the answer is no. Aligatori su veliki gmazovi koji pripadaju redu Crocodilia, što uključuje i krokodile, aligatori, i garijali.
Aligatori su porijeklom samo iz Kine, Meksiko, i Sjedinjene Države. Nema ih ni u jednoj drugoj zemlji, uključujući Kanadu.
Alligators in North America
There is only one species of alligator endemic to North America: američki aligator (Mississippi aligator).
The American alligator inhabits subtropical and tropical freshwater wetlands in the United States, such as marshes and cypress swamps, from southern Texas do Sjeverna Karolina.
The American alligator can grow up to 5.84 m (19.2 ft) in length and weigh up to 1,000 kg (2,200 lb), making it the second largest member of the family Alligatoridae, after the black caiman.
Why There Are No Alligators in Canada Lakes
Alligators are freshwater animals that prefer shallow and slow-moving waters, such as lakes, rijeke, močvare, i močvare.
Međutim, not all lakes are suitable for alligators, as they need warm and stable temperatures, abundant food sources, and protection from predators and competitors.
Canada lakes do not meet these requirements, and therefore, alligators do not live there.
Canada lakes are too cold for alligators, especially in winter, when they can freeze over.
Alligators are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. They need warm and sunny environments to bask and maintain their metabolism.
When the temperature drops below 20°C (68°F), alligators become sluggish and inactive, and when it drops below 5°C (41°F), they enter a state of dormancy called brumation.
Tijekom brumacije, alligators slow down their heart rate, breathing, and metabolism, and stay submerged in water or burrowed in mud to avoid freezing.
Međutim, if the water freezes completely, alligators can suffocate or die from hypothermia.
Canada lakes are much colder than the optimal temperature range for alligators, which is between 28°C (82°F) and 35°C (95°F) . Stoga, alligators cannot survive in Canada lakes.
Canada lakes also do not have enough food for alligators, as they are mostly populated by cold-water fish, such as trout, salmon, and pike.
Alligators are carnivorous and opportunistic feeders, meaning they eat whatever they can catch and swallow, such as fish, kornjače, zmije, ptice, mammals, and even other alligators.
Alligators have powerful jaws and teeth that can crush bones and shells, and a stomach that can digest almost anything.
Međutim, alligators are not very efficient at digesting cold-blooded prey, such as fish and reptiles, as they have a low metabolic rate and a slow digestion process.
Alligators need warm-blooded prey, such as birds and mammals, to provide them with more energy and nutrients.
Canada lakes do not have many warm-blooded animals that alligators can prey on, as most of them migrate to warmer regions or hibernate during winter. Stoga, alligators do not have enough food in Canada lakes.
Canada lakes also do not have enough protection for alligators, as they are exposed to predators and competitors, such as bears, wolves, cougars, and otters.
Alligators are apex predators, meaning they have no natural enemies in their native habitats, except for humans and occasionally other alligators.
Alligators have a thick and armored skin that can withstand bites and scratches, and a strong tail that can whip and knock down attackers.
Međutim, alligators are not invincible, and they can be injured or killed by larger or more aggressive animals, especially when they are young, sick, or injured.
Canada lakes have many animals that can pose a threat to alligators, such as bears, wolves, and cougars, which are larger and stronger than alligators, and otters, which are smaller and faster than alligators.
Stoga, alligators do not have enough protection in Canada lakes.
Why Crocodiles Do Not Live in Canada
Crocodiles are another group of reptiles that belong to the order Crocodilia, but they are not closely related to alligators.
Crocodiles have a narrower snout, with non-overlapping jaws and lighter coloration, and are more tolerant of saltwater but less tolerant of cold temperatures than alligators.
Crocodiles are found in tropical and warm subtropical regions of Africa, Azija, Australia, i Amerike.
The only crocodile species that occurs in North America is the American crocodile (Oštar krokodil), which is restricted to the southern tip of Florida and the coasts of Mexico and Central America.
Crocodiles do not live in Canada because they cannot survive the cold winters and the lack of suitable habitats.
Crocodiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature.
They need warm and sunny environments to bask and maintain their metabolism.
Crocodiles also need aquatic habitats with abundant prey and vegetation to hide and nest.
Canada does not have these conditions, and therefore, crocodiles cannot live there.
