Tonic Immobility in Tiger Sharks | SharkFest


Welcome to Tiger Beach. NARRATOR: Eli recognizes
some of the tigers, but one shark stands out. Her swift movements keep
Eli and Matt on their toes. [grunt] Whoa! NARRATOR: They
name her Jitterbug. Time and again, Eli
must risk a bite to redirect her with his
expert handling skills. [bleep] Yeah, she definitely
has the personality. [bleep] NARRATOR: Jitterbug’s
persistence and curious nature make her a good candidate
for an accelerometer. All right, let’s try
to get a tag on her. Yeah, let’s see where she’s
going and what she does. Did you get it on? Nope, not that one. Let’s do it again. NARRATOR: Jitterbug
is too quick for Matt to safely attach the tag. [grunt] Yeah, she’s
a bit too [inaudible] so we’re going to have to see
if we can settle her down. NARRATOR: Eli has an
idea to help her relax. He’ll put her in a state
of tonic immobility. What I’m going to
do, Matt, is I’m going to rub her nose a little bit. NARRATOR: Around the head and
underside of a shark snout lay small
electroreceptors called the ampullae of Lorenzini. They help sharks detect minute
electrical impulses from prey and are extremely
sensitive to touch. By stimulating
these sensors, Eli is able to calm
Jitterbug and cause her to enter a trance-like state. Here we go! NARRATOR: Eli releases her. This gives Matt a
chance to make his move. You just had it! Yes, it’s on. Awesome!

  1. You would have to pay me Steph Curry's, KD' s, James Harden's and Kevin Love's salaries to put a tag on Jitterbug or any other shark down there.
