Traditional

Translation: defensive turtle

Overview

The Defensive Turtle family covers the turtle positions from the perspective of the defending fighter, who uses the curled-up posture to protect against submissions, pins, and strikes while working to escape. [1] Defensive turtle positions prioritise protecting the neck and arms from attacks while maintaining a stable base that is difficult to flatten or turn over. [1],[2] This family includes the standard turtle (basic defensive posture) and the tight turtle (compressed defensive posture with maximum protection). [2],[3]

History & Origin

Defensive turtle positions have been fundamental to wrestling and judo, where the bottom fighter's ability to maintain the turtle and prevent being turned or pinned is a critical defensive skill. [1] BJJ added neck protection as a primary defensive concern due to the choke threat from behind. [2],[3]

Effectiveness

The defensive turtle tucks the limbs tightly to protect the neck and prevent hooks, used as a survival position when in danger of back control. [1],[2]

Lineage

The defensive turtle is emphasised in judo ne-waza as protection against turnovers and in BJJ as a guard recovery position. [1]

Competition Record

The defensive turtle is commonly used in judo and BJJ competition when guard is lost. [1]

Training Notes

Defensive turtle is the all-fours position used to protect against guard passes and back takes — it is a survival position that must immediately transition to escape or guard recovery (Marcelo Garcia, Advanced Brazilian Jiu-Jitsu, 2011)
Defensive turtle principles: tuck the chin to protect the neck, keep the elbows tight to prevent arm entries, and maintain a tight, compact structure
Defensive turtle is NOT a resting position — the longer you stay in turtle, the more the opponent can attack; escape within 3-5 seconds
The primary escapes from defensive turtle: sit-out (rotate to face the opponent), guard pull (shoot the legs through), standup (post and rise), and roll (forward roll to guard)
The hands in defensive turtle protect the neck: one or both hands should be near the collar/chin to defend choke attempts
Defensive turtle is more common in MMA than in BJJ: fighters turtle when guard is about to be passed to avoid giving up position points
The mental approach to defensive turtle: it is an emergency position; treat it with urgency and escape immediately

Common Mistakes

!Staying in turtle for more than a few seconds — escape immediately; turtle is emergency-only
!Flattening from turtle to a belly-down position — maintain the all-fours structure; flat means defeated
!Not protecting the neck — the chin must be tucked and hands near the neck at all times
!Reaching backward for the opponent — keep the arms in front; reaching back exposes the neck
!Relaxing in defensive turtle — the opponent is actively attacking; maintain alertness
!Using turtle as a guard replacement — turtle is inferior to guard; recover guard as the first priority
!Not training turtle escapes against active opponents — passive drilling doesn't develop realistic escape timing

Frequently Asked Questions

How do I get the seatbelt grip when my opponent is defending their neck in turtle?

Use a distraction by going around their face with one hand, then punch your hand through their defense to get inside and secure the seatbelt grip.

Why do people say the scissor choke from turtle doesn't work?

According to Coach Brian, the scissor choke fails because most people don't position correctly—you end up on the opponent's face without a proper choke, usually just resulting in them escaping. The key is using it as a distraction while your actual control comes from your knee on their chest.

What should I do to prevent my opponent from escaping the turtle position?

Coach Brian emphasizes pulling your opponent to prevent them from returning to turtle, and positioning yourself tightly by getting up on your knee to maintain control and prevent them from jumping their body over yours.

Is the scissor choke or an armbar the simpler approach from turtle?

Coach Brian recommends going for the choke as the simpler and safer approach because it keeps you in a better position rather than taking the risk of transitioning to an armbar.
