Alligators are resilient reptiles that have inhabited swamps and marshes across the southeastern United States for millions of years. When hurricane season hits their habitat every summer and fall, where do these armored animals go to escape the wind and rain?

Alligators Shelter in Place

Find refuge in holes and hollows

When a hurricane hits, alligators will seek shelter in any hole or hollow space they can find. This includes burrows dug into the mud or hollowed out spaces under tree roots or stumps. Alligators are well adapted to hunkering down in holes due to their long, muscular bodies and ability to hold their breath underwater for over an hour.

Experts estimate there are at least two million alligator burrows spread across the southeastern U.S. marshlands. These burrows act as critical shelter sites during major storms. Interestingly, alligators may share burrows with other species trying to escape a storm’s wrath.

It’s not uncommon to find turtles, fish, snakes, raccoons, opossums, and other reptiles and mammals all packed into an alligator den together. While not the most ideal situation, it’s better than facing the brunt of a hurricane head-on.

Submerge themselves in water

If no burrow is available, alligators may opt to sink down into deep bodies of water and wait out the storm. Their nostrils have special valves that seal shut when submerged, allowing them to stay underwater for extended periods without drowning.

Large lakes, ponds, swamps, and retention pools offer protection from wind and surging tides. Alligators will use their powerful tails to propel themselves down to the bottom, where they can remain safely out of harm’s way. Their dark coloration also helps camouflage them from view.

Studies show that up to 70% of alligators in an area will disappear from sight before a hurricane, having submerged themselves as protection. This behavior likely evolved as hurricanes are a regular occurrence in the southeastern U.S. where alligators live.

Wedge themselves under tree roots or brush

If an alligator can’t find a suitable water-filled refuge or burrow, their next best option is to wedge themselves under tree roots, fallen logs, or dense brush. Their low-slung bodies can easily slip into tight spaces beneath natural debris.

Anchoring themselves firmly to resist being swept away is key. Alligators have extremely strong bites, exerting up to 2125 pounds per square inch! Using their massive jaws, they’ll clamp down on any solid structure – a tree root, branch, rock outcrop, etc.

Alligators can then hang on tight, like anchors in a storm. Their rough, thick skin also helps protect them from debris carried by hurricane winds and rains. By hunkering low to the ground in any natural nook or cranny, alligators can safely ride out torrential weather.

Their ability to withstand formidable storms is quite amazing.

The Resilience of Alligators

Able to sense pressure changes

Alligators have an incredible ability to sense even small changes in barometric pressure. Their bodies contain special sensory organs that can detect drops in air pressure that signal an incoming storm. This allows gators to seek shelter or escape flooding before conditions deteriorate.

Survived past hurricanes for millions of years

With this innate weather-sensing capability, alligators have survived countless hurricanes and major storms throughout their over 200 million years of existence. They are remarkably adaptable creatures that know to find higher ground, burrow into thick vegetation for shelter or even submerge themselves in water with just their nostrils exposed to withstand hurricane-force winds and rains.

Fossil records indicate that ancient relatives of modern alligators experienced many prehistoric storms and flooding events. So enduring extreme weather is kind of just business as usual in the alligator world!

Instinctually know to shelter in place

If riding out a hurricane in their natural habitats, alligators rely on pure instinct to seek refuge. Typically, they will retreat to higher elevations if possible, either terrestrial areas less likely to flood or elevated waters that will be more protected.

Alligators have also been known to dig dens into canal banks, bury themselves in mud or hideout among mangrove roots.

In more urban areas that have encroached on alligator territory over time, the resilient reptiles often go into storm drain systems to escape rising waters and find temporary shelter underground. They seem to have a survival strategy for even human-altered habitats.

Habitat Type Sheltering Behavior
Natural wetlands Retreat to elevated banks, float with just nostrils above water, secure themselves among vegetation
Urban waterways Enter storm drains, hide out in drainage pipes and culverts

While their sheltering behaviors vary depending on their locations when a hurricane hits, the main thing is that alligators know to bunker down, stay put and wait out the storm. This resilience is what has enabled the species to live on for so many millennia!

Dangers Alligators Face During Hurricanes

Potential for injury from flying debris

When powerful hurricanes make landfall, they bring intensely strong winds that can pick up and propel debris at high speeds. This flying debris poses a major threat to alligators caught in the storm. An alligator’s armored body and scutes can protect it from some impacts, but a direct hit from a large, fast moving object like a tree branch could still cause traumatic injuries.

In 2005, an alligator was found with a fractured leg bone likely caused by debris after Hurricane Katrina. Alligators face additional dangers from sharp debris that could slice into their flesh and potentially cause life-threatening wounds.Studies have shown alligators with healed-over injuries consitent with lacerations from hurricane debris.

Risk of being swept away by storm surge

The intense winds of a hurricane often push a huge volume of ocean water onto land in what is called the storm surge. These surges can reach over 20 feet high and cause catastrophic flooding. Alligators living in coastal wetlands can get swept up by these violent flood waters.

Once swept away by the surges, alligators face mortal danger from drowning, trauma from colliding with debris, or being stranded far from their aquatic habitats after waters recede. Smaller, younger alligators are especially vulnerable to being overwhelmed and carried off by the surges.

After Hurricane Ida in 2021, alligators were found washed up on roads over a mile from water. Experts estimate hundreds or even thousands of alligators may have perished in Hurricane Katrina’s massive 30 foot storm surge that flooded the Louisiana coastline.

Habitat damage can limit resources after the storm

Hurricanes often down trees, destroy vegetation, and alter wetland landscapes inhabited by alligators. This can have long term consequences by reducing food availability and habitat quality for alligators trying to survive after the storm.

Collapsed trees and vegetation can make it harder for alligators to access basking spots they need for thermoregulation. Destruction of marsh plants leads to increased saltwater intrusion, making water brackish and unsuitable for freshwater species alligators depend on for food.

Studies found alligators showed signs of malnutrition for years after Hurricane Katrina decimated the Louisiana coastal wetlands. The habitat damage combined with changes in predator-prey populations can leave surviving alligators struggling to find enough resources until the ecosystem recovers.

Alligator Adaptations for Storm Survival

Alligators have evolved remarkable abilities to survive the high winds, heavy rain, and flooding brought by hurricanes and tropical storms in their native habitats. Their specialized adaptations help them ride out these extreme weather events.

Armored Skin and Osteoderms Protect Vital Organs

An alligator’s back and tail are covered in thick, armored skin and bony plates called osteoderms that shield their vital organs. This natural “armor” protects alligators from falling trees or debris during storms and serves as a barrier against floods and surging waters.

Ability to Hold Their Breath for Over an Hour

Alligators can hold their breath underwater for over an hour. This allows them to take refuge in flooded burrows and vegetation for long periods until storms pass. Their slow metabolism lets them conserve oxygen even while remaining active.

They simply poke their nostrils out to breathe if conditions permit.

Mating Patterns Result in Late Summer Hatchlings That Can Weather Early Storms

Female alligators build nests and lay eggs in late spring/early summer. The eggs incubate for about two months before hatching in late summer, just before peak hurricane season. This timing allows the hatchlings to grow more robust to withstand early storms.

The attentive mother alligator will also help the young survive initial flooding.

With these ingenious adaptations, alligators are built to outlast whatever tumultuous conditions tropical weather systems throw at them year after year.

Helping Alligators Survive Hurricanes

Preserve wetland habitats as storm buffers

Wetlands serve as natural buffers against flooding and storm surges from hurricanes. By preserving coastal wetlands like swamps and marshes where alligators live, we can help mitigate property damage while also protecting their habitat. According to research from the U.S.

Fish and Wildlife Service, an acre of wetland can store over 1 million gallons of floodwater. Their dense vegetation helps slow down and capture rainwater.

Avoid disturbing alligator shelters after storms

Alligators often shelter in dens and burrows during major storms. While their hiding spots may be exposed due to erosion or flooding, it’s important not not to disturb these areas afterwards out of curiosity. Allow them to recover on their own.

Getting too close could prompt defensive behaviors if they feel threatened. Let trained wildlife professionals assess the situation and provide aid if necessary.

Support trained wildlife rescue groups if needed

In some cases, hurricanes may displace alligators from their natural habitat or injure them. If you spot alligators wandering into developed areas afterwards or see injured animals, contact wildlife rescue services instead of taking matters into your own hands.

Groups like the SPCA have professionals specifically trained to safely capture and relocate displaced alligators and provide medical care if needed before releasing them back into suitable habitats.

Conclusion

Alligators are well equipped to ride out these temporary storms as they have for ages past. By sheltering in place, relying on their adaptations, and with a little human cooperation, alligators are likely to keep thriving across the southeast no matter how many hurricanes may blow through.
