About Caenorhabditis elegans
Description	C. elegans is a nematode worm known for its small size, simplicity, and precise structure.
Life Cycle	It grows from a fertilized egg to a millimeter-long adult within 3-5 days and has provided profound insights into human and biological sciences.
Research Utility	Widely used in studying neuronal and molecular biology.
Scientific Milestones	First multicellular organism to have its full genome sequenced and neural wiring mapped.
Reproductive System	C. elegans has two sexes: hermaphrodite (female-like with limited sperm production) and male. The hermaphrodite can reproduce by self-fertilization or cross-fertilization with male sperm. Self-fertilization allows a single heterozygous worm to produce homozygous progeny.

About Caenorhabditis
elegans

Description

C. elegans is a nematode worm known for its small size, simplicity, and precise
structure.

Life Cycle

It grows from a fertilized egg to a millimeter-long adult within 3-5 days and
has provided profound insights into human and biological sciences.

Research Utility

Widely used in studying neuronal and molecular biology.

Scientific Milestones

First multicellular organism to have its full genome sequenced and neural
wiring mapped.

Reproductive System

C. elegans has two sexes: hermaphrodite (female-like with limited sperm
production) and male.
The hermaphrodite can reproduce by self-fertilization or cross-fertilization
with male sperm.
Self-fertilization allows a single heterozygous worm to produce homozygous
progeny.

What are Nematodes?
Abundance Habitats	Among the most abundant animals on Earth. Habitats Found as parasites in animals and plants, or as free-living forms in various environments like soil, fresh water, marine settings, and unusual places such as vinegar, beer malts, and deep cracks within Earth’s crust.
Physical Features	Bilaterally symmetrical, elongated, and typically tapered at both ends Some species possess a pseudocoel, a fluid-filled body cavity between the digestive tract and body wall.
Global Distribution Parasitic Nematodes	Reported from every continent on Earth, inhabiting diverse environments including deserts, swamps, oceans, tropics, and Antarctica. Commonly found as parasites in almost all organs of animal bodies, particularly in the alimentary, circulatory, and respiratory systems.
