Closed-Jaw Alien Monster

It shows the monster with its jaws shut.

It comes from the Sharp MZ computer’s European alternate display set, a second built-in character table for screen graphics. The MZ-700’s second table was for display, not keyboard entry: BASIC programs could show its characters with POKE, a command that writes a value directly into memory. This one occupied table slot 2D.

Why does the sprite have such a specific name?

The name describes the picture; it is not a known original title.

Legacy computer makers often supplied a code chart or screen image without written names for each design. Unicode proposal writers added descriptive labels like this one and mapped the old character for conversion software, emulators, and text-mode programs that use simple characters to draw pictures.
