Except for some basic gestures when diving
There are also some that identify fish
Let's take a look!
sea turtle
buddy. It's not hard to see that you've spotted a turtle. Fold your hands together and use your thumbs to make circular motions.

shark
Sharks are perhaps the diver's favorite animal to see. If you spot a shark nearby, grab your hand and place it on your head.
jellyfish
Pick up your hand and float like a jellyfish, letting your fingers move backwards like jellyfish tentacles so your dive partner will know there are jellyfish nearby and beware of being stung!
sea horse
Seahorses can't ride, but it doesn't prevent you from playing a game of riding underwater, and finding seahorses is a very pleasant thing
dolphin
If you spot a dolphin, you'd better react quickly! These fascinating marine mammals don't often linger for long. Use your index finger or your hand and undulate to mimic how a dolphin uses its powerful tail to propel itself through the water.
octopus
Imitate the body with one hand in a fist and the fingers of the other hand to imitate the tentacles of an octopus
crab
Crabs are often found hiding in corners and edges or in crevices in reefs. Pinch your fingers together like a crab's pliers.
lobster
Like crabs, lobsters like to hide in crevices in the reef and use your fingers to imitate their tentacles upturned into the air
The above is the underwater fish gesture shared with you today
It's not enough to learn gestures
Catch time by the forelock
Take a diving trip
Wouldn't it be even better?
