Have you ever thought about whether shark can smile? We will answer this interesting question below. As we know dogs, monkeys and dolphins may show some expressions. And when we look at the shark as if the shark can smile.
In sharks and other fish, the parts of the brain related to feelings aren’t developed enough to produce a smile.
Some animals can express different kinds of feelings such as happiness, anger and fear. All of these creatures show facial expressions akin to human smiles.
On the other hand, some sharks really do look as if they’re smiling, like the lemon shark that made the rounds on Twitter in 2016, after being caught on film by Kenneth “Wayne” MacWilliams in Juniper, Florida.
“So can shark smile? It’s not likely. And scientists warn against reading too much into animal faces and behaviors. That sort of anthropomorphizing – attributing human form or behavior to animals – can get in the way of scientific objectivity, they say. Still, future scientists are sure to discover more about sharks’ relationship with their world, giving us all a better glimpse into the lives of the creatures who co-inhabit planet Earth with us”, mentions earthsky.org.
So, to come up to this question we surely can say. Not likely. Sharks do not smile. But dogs, monkeys and dolphins all show expressions akin to human smiles.
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term “shark” has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans.
