Definition

1. Verb:
   • To cause a body part to undergo autotomy: This is a biological term meaning to intentionally shed or cast off a part of the body, typically as a defensive mechanism to escape a predator. The process is reflexive and self-induced by the organism.

Usage

• The verb "autotomise" describes the specific action where an animal, such as a lizard or a starfish, deliberately detaches a limb or appendage.
• It is a transitive verb, meaning it takes a direct object (the body part being shed).
• This term is primarily used in scientific, zoological, and biological contexts.

Examples

• Verb:
  • When grabbed by the tail, some lizard species can autotomise it to escape.
  • The sea star will autotomise an arm if it is severely injured or captured.

Advanced Usage

• "to autotomise a limb": This is the most common collocation, specifying the body part that is shed.
  • The mechanism that allows crabs to autotomise a limb is a fascinating adaptation.

Variants and Related Words

• Autotomy (n): The noun form referring to the act or process of self-amputation.
  • Caudal autotomy is common in many lizard species.
• Autotomize (v): An alternative spelling, primarily used in American English.
• Autotomised/Autotomized (adj): The adjective or past participle form describing a body part that has been shed.
  • The autotomised tail continued to twitch on the ground.

Synonyms

• Self-amputate: A more general, descriptive synonym.
• Cast off: A less technical term that can be used in a similar, though not identically specific, biological context.
• Shed: A broad term for losing a body part, which can include non-defensive processes like molting.

Notes

• "Autotomise" is a highly specialized term. In everyday language, one would more commonly say "shed its tail" or "drop its leg" instead of using this precise scientific verb.
• The direct object of the verb is almost always the detached body part (e.g., tail, limb, claw), not the predator or the cause of the threat.
