What does a saltwater crocodile sound like?
Saltwater crocodiles produce a range of sounds, often used for communication and signaling. Their vocalizations include deep, resonant growls, which can sound like a low rumble or a booming roar. These growls are typically heard during mating season or when they feel threatened.
They can also produce hissing sounds when they feel threatened or are warning off intruders. Young crocodiles emit a series of high-pitched squeaks or whistles, especially when they are distressed or calling for their mother.

What is unique about Saltwater Crocodile maternal care?
Female saltwater crocodiles build nests on riverbanks and guard their eggs fiercely. After hatching, she will carry the hatchlings to the water in her mouth and protect them until they are strong enough to fend for themselves.
What makes Saltwater Crocodiles such effective hunters?
These crocodiles are stealthy hunters, using their camouflaged scales to blend into their surroundings. Their eyes, ears, and nostrils are on top of their heads, allowing them to remain almost completely submerged while spotting prey. They also have a unique feeding strategy known as the "death roll," where they twist their bodies to tear apart prey or dislodge it from their grasp.
How long do Saltwater Crocodiles live?
Saltwater Crocodiles have impressive longevity, living over 70 years in the wild. They continue to grow throughout their lives, although growth slows as they age. Saltwater Crocodiles have been around for millions of years, with their lineage dating back to the time of the dinosaurs. They are considered living fossils, retaining many features from ancient crocodyliforms.
