epimorphic

Thân thiện

A caterpillar undergoes epimorphic development, retaining its body segments as it grows.

Definition

1. Adjective:
   • Characterized by incomplete metamorphosis: In biology, "epimorphic" describes a type of development or metamorphosis where the organism does not undergo a complete transformation through distinct larval and pupal stages. The juvenile form often resembles the adult.
   • Having the same number of body segments in successive stages: Specifically, it refers to growth where the number of body segments remains constant from an early stage through to adulthood.

Usage Examples

• Adjective:
  • Some insects, like silverfish, exhibit epimorphic development, showing little change in form as they mature.
  • In epimorphic growth, the creature adds size to its existing segments rather than developing new ones.

Advanced Usage

• Technical/biological context: The term is almost exclusively used in specialized biological and entomological texts to describe developmental patterns.
  • The study focused on the epimorphic regeneration of the salamander's limb, where the new limb replicates the original structure precisely.

Variants and Related Words

• Epimorphosis (n): The process of epimorphic development or regeneration.
  • Epimorphosis is a key area of study in developmental biology.

Synonyms

• Ametabolous (in entomology, for development without metamorphosis).
• Direct development (a broader descriptive term).

Antonyms

• Holometabolous (characterized by complete metamorphosis).
• Hemimetabolous (characterized by incomplete or simple metamorphosis, though this is distinct from the specific segment-count meaning of "epimorphic").
