ACOEL Meaning and
Definition
-
Acoel is a biological term that refers to a member of the Acoelomorpha, a group of small, worm-like animals that lack a body cavity, or coelom. Acoels are considered simple invertebrates and are primarily marine organisms found in various habitats such as sand, mud, or coral reefs.
These animals are typically small, measuring a few millimeters to a few centimeters in length, and have a flattened, elongated body with a soft, flexible outer covering called a tegument. They lack any specialized respiratory, circulatory, or excretory systems.
Acoels are characterized by their unique body plan, which includes a simple, blind sac-like gut, a mouth located on the underside of their body, and a statocyst, a sensory structure that helps them orient themselves in their environment. Despite their simplicity, some acoels possess a branched nervous system that allows them to respond to external stimuli.
Acoels are primarily predators or scavengers, feeding on small organisms such as microscopic algae or tiny invertebrates. They use a muscular pharynx to engulf their prey and digest it extracellularly before absorbing the nutrients. Reproduction in acoels can occur both sexually and asexually through processes like fission or budding.
Due to their unique characteristics and evolutionary position, acoels have been the subject of scientific study and debate, shedding light on the early evolutionary history and relationships of different animal groups.
