Nurse shark anatomy

Here's a little anatomy lesson on nurse sharks:

Big flat head: Ideal for ramming into cracks to get lobster lunches;

Tiny eyes: This is not a visual predator;

Barbules: You can just abou make out two small sensitive barbel/barbule type thingys around its mouth ideal for finding prey buried in sand.


Massive pectorals for sleeping on.


Rearloaded fin array: Notice the two dorsals are pushed way back almost into the tail. Ideal for short bursts of speed but not continuous cruising.
