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
