    Does ultrasonic sensor works in water?Does it cause any harm to fish and shrimps?
    How we should detect the shape of the object using sonar sensor?

    Welcome to EP!
    Some ultrasonic sensors are designed to work in liquid, others aren't.
    High enough sound/ultrasound levels can stun or harm animals.
    Shape detection would depend on the size of the object relative to the transducer dimensions and operating frequency. Sonar, with a directional beam, is commonly used to map sea-bed shape and to image wrecks.
