Scary Triangles

Title text: Concealed mostly beneath the surface, sharks are the icebergs of the sea.

Explanation

This explanation may be incomplete or incorrect: Created by the Bermuda Triangle of the sea - Please change this comment when editing this page. Do NOT delete this tag too soon.

Cueball is giving a marine biology lecture about sharks and seems to have mixed up icebergs with the topic.

In pop culture, sharks will often approach prey or people with only their front dorsal fin visible, which looks like a triangle, above the water. As far as prey are concerned, this is inaccurate, as most sharks will attack from below to keep the element of surprise.

In the comic the joke is that Cueball reveals that marine biologists have only recently learned that the triangle is only a small part of a shark. Until this revelation people were only aware of the visible portion, and the fact that death and injury often occurred when they arrive, causing them to be known as 'scary triangles'. Finally the community has learned that more than 90% (i.e. the rest of the shark's body) is hidden beneath the surface. (In most, if not all, cases it would actually be significantly more than 90%.)

The 90% is borrowed from an often cited factoid about icebergs: that 90% of their volume is underwater. (This would be true for clean ice in freshwater, but in reality icebergs are filled with air cavities and float in salt water, so although most of an iceberg is beneath the surface, it is somewhat less than 90%.) Having learned that a similar fact is true of sharks, Cueball has drawn a dotted outline of the shark's body, equivalent to that often depicted in diagrams of icebergs, beneath the scary triangular fin, to show what a shark looks like under the surface.

The title text continues the joke explicitly, saying that sharks are the "icebergs of the sea." However, icebergs are already in, and thus also "of," the sea.

Transcript

[Cueball points with a stick to a poster hanging behind him to the left. The poster has a diagram of a shark. The dorsal fin is shown above a wavy surface of water. The part of the outline of the shark that are under water are drawn in dashed lines. There are unreadable text in the top and bottom left corner, and two labels with lines that points to its dorsal fin and its gills. Cueball's stick points to the label near the gills]

Cueball: Today's marine biology lecture is on sharks. We all know them as the scary triangles of the sea, but recent research has revealed that the triangle is only a small portion of the shark - over 90% of it is hidden beneath the surface.
