### discovery | determination:

Echolocation
* Most echolocation takes places.
* allows bats to detect even slight movement
  - evaluate targets with precision
  - navigate in total darkness and to detect and capture food on the wing
  - dolphins to find things without using sight
* also helps the bat to move around
  - permits bats to navigate through deep caves in total darkness
* begins with a series of clicks that accelerates into almost a buzz.
* description of the function of particular biosonar use.
* enables a bat to detect objects as small as a mosquito while flying in the dark
  - bats to capture small flying insects and to avoid obstacles in their path
* form of a. active sonar.
* has a different name, it is sonar.
* informs the dolphin of the size, shape and movement of an object.
* is an ability that babies have to learn how to use
  - adaptation for navigating in visually limited environments
  - interesting phenomenon to study for various reasons
  - as important to dolphins as sight is to most land mammals
  - basically a process where bats are producing sound waves
  - clearly one of the most fascinating aspects of the biology and behavior of bats
  - dolphins making a high pitch noise which bounces off other objects
  - extremely sensitive
  - like sonar , which submarines and ships use to find things underwater
  - localization
  - much like radar, the bat bounces sound off objects to ascertain their direction
  - orientation by analysis of echoes from sound pulses
  - probably a major tool in food-finding and navigation
* is similar to sonar
  - sound found in bats
  - sort of like radar or sonar
* is the ability to see through sound
  - primary source used to locate food and to guide it toward or away from objects
* is the same as active sonar , using sounds made by the animal itself
  - process used by doctors for ultrasound imaging
  - way all dolphins communicate with each other
  - thought to aid in the search for food
* is used by animals such as orca, and bats and system similar to submarine sonar
  - primarily to locate food
* is used to find prey and orient to the surroundings
  - locate food and fellow baiji in the muddy water
  - when a whale sends sounds out that bounce off objects
* means they use echoes to find where things are.
* method of orientation which uses pulses of sound and their echoes.
* presumably is used to avoid obstacles and to search for prey on the bottom.
* trait that is found in all species of toothed whale.
* very effective way to hunt for insects and avoid obstacles in the dark of night
  - precise way of sensing the environment
* way of using sound to find objects in the environment.
* works like 'radar' and is used by dolphins to find food - like schooling fish.
+ Bat, Adaptations, Echolocation
  * An interesting thing about bats is that even though they can see with their eyes, they also use their ears to help them 'see' in the dark. Because of this, they can fly into very dark places where no eye could see. This way of sensing is called 'echolocation'. Echolocation means they use echoes to find where things are.
  * Echolocation is like sonar, which submarines and ships use to find things underwater. Biologists have instruments to record them, and then play them back at a lower frequency so humans can hear them.
