How Come Some Adult Elephant Seals Dont Have Big Noses?
Why do male and female elephant seals look different? Adult male elephant seals belonging to the northern species tend to have a larger proboscis, and thick chest area with a red coloration compared to the southern species. Females do not have the large proboscis and can be distinguished between species by looking at their nose characteristics.
What are elephant seals noses called? The nose of the male elephant seal elongates at puberty (7-8 years old) into an inflatable “proboscis.” This is used during reproduction when the males establish territories. The territories are established by fighting – both physically (by lunging at each other) and vocally (using their large nose).
Why do elephant seals put their noses in their mouth? It’s hard not to laugh at the appearance of an adult male elephant seal. His massive head is dominated by a large bulbous nose that droops over his mouth when he’s relaxed. When he’s asserting his maleness—usually to rivals—he rears back his head and inflates that big schnoz like a balloon.
