dugongs and manatees,
Sounds very different,
But they look alike.
Xiaobian first above the picture,
You can tell which is the dugong,
Which is the manatee?
I guess your inner activities are as follows:
They don't seem to be unrelated.
It's exactly the same.
In fact
Manatees and dugongs are really two species,
But it belongs to the same order Manatee.
The most obvious difference between them is the tail,
The tail of the manatee is nearly rounded;
The tail of the dugong is crescent-shaped and very similar to the tail of cetaceans.
Their heads are different,
The head of the manatee looks more normal;
The dugong's head looks a little strange,
There is an angled nose and mouth.

In terms of teeth,
Manatees have a row of molars,
The new teeth in the back will continue to move forward,
Replace worn teeth;
And the dugong's head has only a few molars like pig teeth,
These molars grow for the rest of their lives,
furthermore
Male dugongs have long incisors that form tusks.
Look closely at their hands (forelimbs),
Manatees have toenails on their forelimbs (except for Amazon manatees),
Looks a bit like an elephant's feet,
This is because manatees are close relatives of elephants;
And the forelimbs of the dugong are bare,
Without toenails, it looks very ordinary.

Seaweed is often attached to its head and back;
