Definition

Noun: 1. A type of crab characterized by very long legs and a relatively small, often triangular-shaped body: This term refers to any crab belonging to the family Majidae (or Inachidae), known for their distinctive, spindly legs which make them resemble spiders. Their bodies are typically smaller in proportion to their leg span.
