1

What are the 5 sensory systems fish use to detect each other?

1. Mechano reception
2. Electro reception
3. Vision
4. Chemoreception
5. Magnetic reception

2

What do these 5 sensory systems mean?

1. Touch
2. Detect Electricity
3. See better in Water
4. Taste
5. Detect Magnetic Fields

3

Name the parts that fish use with their Mechano reception?

1. Lateral Line System
2. Inner Ear
3. Neuromasts (Nerve cells) that detect vibrations

4

What are the functions of the Lateral Line System?

1. Touching at a distance
2. Schooling Behavior
3. Predation
4. Hydrodynamic Imaging
5. Courtship Communication
6. Subsurface Feeding
7. Surface Wave Feeding
8. Orientation

5

Where are the Otoliths located and their function?

1. On sensory hair cells
2. Provide downward pull of gravity

6

Otoliths are also called what?

Bony/Ear Stones

7

What is the function of the Weberian Apparatus?

Transmit vibrations from gas bladder to the inner ear for detection by the Otolith Organs.

8

What are the sensory organs of Olfaction?

1. Chambers
2. Epithelia
3. Taste Receptor Cells

9

What are the Olfaction Chambers made of and their function?

1. Made of pits with epithelia and nerve snares covered with flap of skin
2. Directs Water over the epithelia

10

What are the Olfaction Epithelia made of?

1. Made of folded tissues in rosettes with chemo-receptor proteins

11

Taste Receptor Cells are often are clumped into what?

Taste Buds

12

What is the function of Ampullary Receptors?

Detect electrical currents

13

Why is salt water better for communication between fish?

Higher ionic concentration that makes it a good conductor of electricity

14

What do electrical organ discharges (EODs) use to send signals of electricity?

1. Produce electrocytes
2. Modified muscle cells called electra plaques

15

Electrogenic Fish

Fish capable of generating an electric field

16

Electroreceptive Fish

Fish capable of detecting electric fields
