Can you hear whales in a submarine?
Whales, Dolphins, shrimp, fish, you name it - if it makes noise in the water, it can be picked up and heard by submarine passive sonar systems. As an old Submarine Sonarman myself, I can tell you that Humpback whales make the most beautiful (and haunting) songs in the ocean. Sperm whales make a high-frequency "clacking" sound, similar to whacking a pair of 2x4's together. Dolphins make a very high-frequency squealing noise, which can be irritating when they're really close. They tend to turn up when a boat comes to Periscope Depth, as do other fish, shrimp, and various other sea critters, especially at night. Unless you're really close to a Humpback whale though, it's difficult to impossible to hear one through the hull directly because of the constant noise of machinery - electronic systems, electrical fans, hydraulics, engines, etc.
What do dolphins have to have to be able to hear under the water?
sonar
How do you know if a fish is a fish?
If the creature/animal has scales and a fin then it is a fish. Whales have smooth skin so it's a mammal. Dolphins have smooth skin so it's a mammal try asking him. i hear most fish are quite approachable.
How does the military sonar affect whales?
Sonar affects most marine mammals in a very negative way. It can cause them (especially whales) to dive down very deep and surface too quickly in an effort to escape the sound. This causes them to suffer from an ailment that we commonly know as 'the bends' it causes headaches, nosebleeds and, depending on the severity, fatal haemmoraging. It also, as most marine mammals use sonar to navigate, causes them to lose their way when they hear the artificial signals as they confuse them. Many whales get beached and often die.

How do killer whales hear and talk?
Orcas speak by producing noises and clicks known as sonars at a certain frequency which is like how humans speak. Orcas hear by receiving sonar and other sounds through the lower jaw bone to be transmitted to the inner ear. This is possible as the lower jaw bone is hollow.
