Salient Feature of Ctenophora | B.Sc. Zoology 5th Semester | Paper-1st | Unit-3 | NEP-2020

Ctenophora, also known as "comb jellies," are a group of marine invertebrates known for their distinctive appearance and unique features. Below are the key characteristics of the phylum Ctenophora: Body Structure and Symmetry Radial Symmetry: Ctenophores exhibit radial symmetry, meaning their body parts are arranged around a central axis. Gelatinous Body: They have a soft, translucent, and gelatinous body, often with a "jelly-like" consistency. Body Shape: Their bodies are usually oval or cylindrical, with a flexible, transparent surface. Lack of Exoskeleton: Unlike many other marine organisms, ctenophores do not have a hard exoskeleton or shell. Ciliary Movement: Their movement through water is unique due to the action of their ciliated combs, which gives them a "shimmering" appearance. Ctenophores are fascinating marine organisms, distinguished by their gelatinous bodies, ctenes (comb rows), bioluminescence, and their role in marine ecosystems. Their simple yet effective anatomy and behavior contribute significantly to the diversity of life in marine environments. Sexual Reproduction: Ctenophores are typically hermaphroditic, meaning they have both male and female reproductive organs. Fertilization is usually external. Eggs and Sperm: The eggs and sperm are released into the water, where fertilization occurs. Development: The fertilized egg develops into a ciliated larva, which undergoes further development into the adult form. #zoology #bscbotany #zoologymcq #science #chemistry #bscbotany #bscchemistry #physics #zoologyfacts #zoologynotes Join this channel to get access to perks:    / @letsstudyindia   ======================================== Thank-You For Watching This Video...!!
