Answer:
First person recalling a past event.
Step-by-step explanation:
In the given excerpt of the passage from "Sharks' Teeth" by Langston Carter, we see the narrator/ speaker using the first person "We" throughout the passage. The narrator talks of how he, along with other 'friends' or even maybe 'relatives', found the sharks' teeth.
Again, the use of the past tense verb form signifies that the event the narrator is talking about is from the past. And it was a personal experience, which makes the present passage a form of recollection of what had already happened. Thus, the whole passage has been narrated by a first person narrative voice, recalling a past event that he/she had personally experienced.
