1. Mouth: the position of a fish’s mouth can indicate whether a fish consumes prey from the surface, in front of it, or the sea floor.

2. Superior Mouth: the mouth is positioned toward the surface and the fish feed on what is above them

3. Terminal Fish: the mouth is positioned in the middle of the head and the fish either chases its prey or feeds on what is ahead of it

4. Inferior: the mouth is positioned toward the bottom and the fish prey upon or scavenge food on the bottom of the marine or freshwater source

5. Which type of mouth shape do you see on this fish?

6. Superior Mouth (This is a Tarpon)

7. What kind of mouth does this fish have?

8. This Mosquitofish has a terminal mouth orientation.

9. What kind of mouth does this fish have?

10. This Gulf Kingfish has an Inferior mouth

11. Now let’s talk about the Caudal Tail!
Did you know that you can tell how quickly a fish moves by its Caudal Tail?

12. Remember that the Caudal Tail is connected with the speed and strength of a fish’s forward movement:

13. Continuous Caudal Tail:
Fish swims at a slow speed but can maneuver well
This fish will be able to swim into crevices and caves well
This is a cobbler

14. Lunate Caudal Tail: Very fast fish Can maintain high speeds
Lack of surface area on tail means that they cannot stop or turn easily (ex. Bluefin Tuna)

15. Forked Caudal Tail:
Cruising fish that swims continuously at a fast rate
Extra fin surface area provides better maneuverability than a fish with a lunate tail
This is an Australian Herring

16. Truncate Caudal Tail: Cruises at an intermediate (in the middle) speed
Good maneuverability due to large amounts of surface area on fins
This is a Mangrove Jack

17. Rounded Caudal Tail: Fish swims at intermediate (middle) speeds
Can maneuver well because of large amounts of surface area on the tail
This is an Estuary Cod
