Defensive turtle
Also known as Turtle — Bottom (Defending) — the canonical term used on this site.
Descriptive — turtle position in defensive context
Defensive turtle is the descriptive name for the turtle-bottom position — flagging the defensive intent that distinguishes this version of turtle from offensive turtle-top configurations.
Etymology. “Defensive” specifies the tactical role; “turtle” attaches the body-position-family name. The compound predominates in instructional vocabulary that distinguishes the turtle as a defensive base vs. as a target for top-position attacks.
Mechanics. The defensive turtle’s four-point base denies the attacker hip access while the bottom player works back toward a more neutral or guard configuration.
Cross-reference. “All-fours position (defensive)” and “turtle base” are alternate names. Full mechanical coverage on Turtle Bottom.
