(of an animal) to cast off a part of its own body as a defense mechanism.
To shed or cast off a part of oneself, usually by reflex action, to escape danger or attack.
Linguistics
Semantic Notes
This verb is primarily used in zoology and biology contexts. The process is involuntary, often a reflexive action triggered by stress or threat, and differs from intentional shedding. It is typically applied to animals like lizards (tails), arthropods (legs), or sea cucumbers (internal organs).
Dialectal Variation
British vs American Usage
Differences
Spelling: British 'autotomise', American 'autotomize'. This is the only consistent difference. Both variants are used in scientific writing according to regional orthographic conventions.
Connotations
No connotative differences; both are strictly technical and neutral.
Frequency
Extremely rare in both varieties. No significant frequency difference; found exclusively in scientific and academic zoology texts.

Examples
By Part of Speech
verb
British English
- The common lizard can autotomise its tail to escape a predator's grasp.
- If handled roughly, the harvestman may autotomise one of its long legs.
American English
- The gecko will autotomize its tail at a specific fracture plane.
- Researchers observed the sea cucumber autotomize its internal organs as a defense.
adverb
British English
- The limb broke off autotomisingly as a last resort.
American English
- The tail detached autotomizingly at the pre-formed breakage point.
adjective
British English
- The autotomising reflex is triggered by nerve signals.
- This species exhibits an autotomised limb stump.
American English
- The autotomizing species was studied for its regenerative abilities.
- An autotomized appendage can continue to twitch, distracting predators.
Examples
By CEFR Level
- A lizard can drop its tail if a bird catches it. This is called autotomy.
- Some animals have a special ability to lose a body part on purpose to get away. When they do this, they autotomize.
- The crab autotomized its claw, leaving it behind in the attacker's mouth while it escaped to safety.
- The evolutionary advantage of the ability to autotomize lies in the trade-off between losing a limb and preserving the organism's life, thereby enhancing its long-term fitness.
Learning
Memory Aids
Mnemonic
Think: AUTO (self) + TOM (cut) + IZE (to make) = to make oneself cut off a part.
Conceptual Metaphor
[DEFENCE IS SELF-SACRIFICE] - Surrendering a small part to preserve the whole.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'autotomy' (the process/ability) and 'autotomize' (the action).
- Avoid using 'autotomize' as a general synonym for 'cut off' or 'amputate'; it implies an organism's own defensive reflex.
Common Mistakes
- Using it transitively for the severed part (e.g., 'The predator autotomized the tail' is incorrect; the *lizard* autotomizes the tail).
- Confusing it with voluntary shedding or molting.
- Using it in non-biological contexts.

FAQ
Frequently Asked Questions
No, it is typically a reflexive, involuntary defence mechanism triggered by stress or predation.
The noun is 'autotomy' (the process or ability). An act of autotomizing is an 'autotomy'.
The term is almost exclusively reserved for animals. Plants may 'abscise' (shed) leaves or fruit, but this is a different process not termed autotomy.
Often, the lost part can regenerate over time (e.g., a lizard's tail), though the new part may differ in structure from the original.
