Vocal sounds made by these lemurs are described as a loud shriek and are typically used during the day. The vocalization is used to communicate within the group to notify each other when changing locations, spacing of group members or predator threats. However, their vocal calls to each other don’t seem to be used when establishing territories.
Despite their lack of development at birth, by the age of 7 weeks the young are able to fully mobilize themselves as if they were full grown adults!
While most of the group is foraging, one mob member acts as sentinel, keeping watch and sounding an alarm if predators are seen. Sentinel duty rotates throughout the group in the course of a day, and switching of duty is announced vocally.
Anti-predator behaviors include alarm calling, running for cover, mobbing, defensive threats, and covering the young.
If you see a seal pup on the beach, you should leave it alone and keep your distance. A mother may have left it on shore to go fishing (young harbor seals can’t swim), but she will soon return to care for her pup.
They have large eyes with flattened corneas that allow them to take in more light and see well underwater.
Their whiskers detect sound waves, which helps them locate prey.
A group of foxes is called a “skulk” or a “leash.”
The fur of the Arctic fox changes twice yearly. The winter fur is thicker and entirely white, providing camouflage against snow and ice; the summer coat is gray and brown, blending in with the tundra and grassy hills.
Their thick, heavy tails provide cover in cold weather.
