So why otters scream every time. The vocal repertoire of the giant otter deserves more scientific attention. A new study shows that South American mammals produce 22 different adult vocalizations, including whistles, three types of calls and various buzzes.
Researchers have documented both wild and captive animals. Adult giant otters often bark to greet group members, giving a short screech when they emerge from the water. The “ha ha” sound can be a warning or a sign of surrender. The giant otter (Pteronura brasiliensis) can weigh up to 34 kg, slightly more than the average 10-year-old, and usually lives in groups of three to nine. The remaining 12 species of otters include solitary and social animals. Otters therefore provide a missed opportunity to test ideas about how social life affects the complexities of vocal communication.
Why otters scream every time – What sounds do otters make?
Otters can and do use vocalizations to communicate; this is more common in family groups and in groups of males, which can have more than ten animals. North American river otters can produce several types of vocalizations. The study details the types of vocalizations in two pairs of otters in captivity.
The study found that the most common type of call was the “squeak,” which is described as a “short, shrill” call and is an excited call most often used when otters stand still or watch.
Another noise in the studio was the “chirp,” a series of tweets in rapid succession. These vocalizations are associated with states of hyperarousal and often occur during physical fights. Otters also have screeches, described as “howling wails”, which last an average of about 2 seconds and consist of whimpers and screeches. This chirp is used only in response to a person’s presence and occurs during restless behavior such as moving. This suggests that screech-like vocalizations may help otters avoid physical conflict with other otters and other species.
Why otters scream every time – Whistle
Hissing is a familiar sound made by otters and is rarely recorded in otters or otters. It sounds very similar to a chirp, but it is harmonically muted. Pups often use this call to explore the birth nest or find their mother. Interestingly, purrs, squeaks, and squeaks are the otter’s main vocalizations and are present in pups from birth. Pup vocalizations are undeveloped versions of adult vocalizations with individual differences. Almont believes this is because vocalizations change individually as they mature. This means that otters have unique sounds, just like humans. The otter growls, like a man clearing his throat; this call is inconspicuous and is usually used when the otter is slightly agitated or agitated.
Why otters scream every time – Do otters use body language to communicate?
Although otters communicate primarily by scent because they are solitary animals, some evidence suggests that otters also use body language to communicate. Otters show affection for their young through play, petting, and body gestures. It is believed that the cubs can tell if their mother is “pleased” with them or try to discipline them with her position.
Male otters can also be seen in bathrooms doing something that creates a “poop dance” where the male otters raise their tails at a very high angle and then stomp. It has been observed that when an otter uses this behavior. It encourages other otters to do the same.
