Use this website to fill in the missing information for the following marine fish. All of these fish are found here in southern California waters so make sure you are looking up species whose distribution includes southern California.

1.Common Name: Pacific Angel Shark

a.Scientific Name:

b.Photo (copy and paste a photo of this fish here):

c.NativeRange Map (copy and paste the native range map of this fish):

d.What is the maximum reported age of this fish?

e.Describe what type of environment (i.e. pelagic, benthic, in reefs, etc.) this fish would live in based on fin position, body shape, and coloration pattern.

f.Click on the photo of this fish to view more photos. Click on the photo of the mouth so you can see it up close. Describe what type of food this fish would eat based on mouth shape/size and tooth shape/size (carnivore, herbivore, filter feeder etc.).

To identify fish in which you only have a photo of, use FishBase and click on “Quick Identification”. Use the provided photoand read the group description on FishBase to determine what group of fish the unidentified fish would belong to and then click on that group. Again, use the photo to determine what order of fish the unidentified fish would fall under and click on that order. Keep going until you identify the fish. Remember, that these fish are found off of southern California so make sure you select the fish whose distribution includes southern California.
