Do dolphins have ear holes?
Marine mammals also need a streamlined head for fast and easy movement through water that external ears would impede. Instead, they have ear holes located right behind the eye. In bottlenosed dolphins, the ear hole is only 2-3 millimeters in diameter.
How far away can dolphins hear?
In shallow areas with a mud bottom, all whistle frequency components of the same whistle could be heard by dolphins travel up to 2 km. In channels, high-frequency whistles (13-19 kHz) could be detectable potentially over a much longer distance (> 20 km).
Where are whale ears located?
Unlike land mammals that have ears attached to the skull, the middle and inner ears of cetaceans are encased in bones that are located in a cavity outside the skull. In odontocetes, these bones are attached to the skull by ligaments.
Can dolphins hear human voices?
Conclusion. This study shows evidence that bottlenose dolphins are able to respond to individual sound cues produced by humans, even when sounds are emitted in the air. Further studies could test if dolphins can associate these sound cues with individual identities.
Is it OK to touch a dolphin?
Never touch or pet dolphins, even if they come close enough to touch. Use binoculars to watch dolphins from a safe distance in their natural habitat instead.
Do dolphins feel love?

SWTD programs have reported human injuries including lacerations, tooth rakes, internal injuries, broken bones, and shock.
Do dolphins save humans from shark attacks?
Whenever a member of the group is in danger from a shark, the rest of the pod rushes in to defend their buddy. Dolphins have even been known to protect humans in danger of sharks.
How do dolphins see humans?
Dolphins use echolocation to create an impression of the world around them. These pictures hold a wealth of three-dimensional information like depth, making it difficult to translate into flat images. “Seeing the 3-D print of a human being left us all speechless,” Kassewitz said in a statement.
Do dolphins see color?
Dolphins have limited color vision and poorer visual acuity, or clearness of vision from a specific distance, both in air and under water than primates.
Do dolphins have a sixth sense?
Dolphins have a sixth sense that we are missing: echolocation. They produce sounds in their nasal cavities that are sent out through the melon, their fat-filled forehead. These sounds bounce off an object and return as an echo to the animal through its fat-filled jaw.
Do dolphins see better underwater?
Dolphins are mammals, and as mammals, they have lungs. They have hair. And fascinatingly enough, their eyes have not yet adapted back to the perfected aquatic eye. Instead, they have picked up another sense, their echolocation, that helps them “see” better underwater.
