when it comes to penguins, the general impression is mostly cute, round, walking naively, QQ (not) and so on. In short, they are still very likable.

(a lovely childhood memory)

however, if you see what the penguin's mouth looks like, the painting style will suddenly become different.

for example, this picture, which is widely circulated on the Internet:

(I hope it doesn't scare you)

reveals its mouth full of "teeth", and the penguin instantly becomes a scary painting style. However, these are not teeth, they are barbs distributed on the upper jaw and tongue, and they are completely different from the structure of our teeth.

these barbs are important tools for penguins to make a living. Imagine catching slippery fish in the sea and swallowing them alive. if the mouth is naked, the fish in the mouth will easily run away. with these thorns, you can easily trap the fish and eat them smoothly. Not only penguins, but many other fish-eating seabirds also have a similar structure.

There is nothing more desirable than one of our high neck wedding dress. We have cuts and forms to fit any silhouette.
