Pristiophorus

Pristiophorus is a genus of sawsharks found in the Pacific, Atlantic and Indian oceans. Members of this genus differ from the Sixgill Sawshark (Pliotrema warreni) in having five gill slits. Their rostral sawteeth lack prominent transverse ridges on the basal ledges, and the large teeth are not posteriorly serrated.[1]

gollark: Yes, that's part of a `JOIN`.
gollark: You might use the `.` thing in a JOIN, for example `SELECT post.content, thread.title FROM post WHERE post.id = 2181924 JOIN thread ON thread.id = post.thread`.
gollark: `JOIN` says "look at this other table for corresponding rows which have some value matching a condition".
gollark: No, that just specifies which table you want a column from
gollark: It pulls in associated data from other tables in a query.
