What is the function of a statocyst?
Statocysts are structures that aid in orientation and balance during swimming in medusae and are located around the margin of the bell in Craspedacusta and similar medusae (Payne, 1924).
Which animal has statocyst as their sense organs?
The statocyst is a balance sensory receptor present in some aquatic invertebrates, including bivalves, cnidarians, ctenophorans, echinoderms, cephalopods, and crustaceans. A similar structure is also found in Xenoturbella.
What function does the statocyst do in the crayfish?
The statocyst is responsible for balance and such reactions as rising to the surface of the water or sinking.
How does a statocyst act as a transducer?
What can you conclude from Fig 2.1 about the mechanism by which a statocyst acts as a transducer? Kinetic energy is converted into an action potential as movement of statolith moves sensory hairs. There is weak support as classification is based on phylogeny, statocyst could be an example of convergent evolution.
Do flatworms have statocyst?
Platyhelminthes: Catenulida: Catenulidae: Genera Statocyst present. Paired refractile organs behind the posterior brain lobes absent. Gut excretophores absent.
What is the function of Ocelli and statocyst?
The ciliated pits and grooves contain chemical receptors, or chemoreceptors, which permit the animal to detect food. The statocyst is responsible for balance and such reactions as rising to the surface of the water or sinking.
Is statocyst present in Ctenoplana?
-These organisms communicate via pheromones. So, the correct answer is, ” Statocysts are found in Palaemon.” Note: Arthropods are the most successful invaders of the terrestrial environment and amount all the invertebrates because of the presence of cuticles, appendages, and wings.
What are Statocysts in jellyfish?
Statocysts, the balance organs of jellyfish, are located at the bell rim of the medusae. They contain tiny crystals, the statoliths, representing the only solid and inorganic structures in the gelatinous medusa bell.
What is the function of statocyst in prawn?
Statocyst provides an information related to the movement of an animal to the brain which helps the animal in maintaining their balance it is mostly found in arthropods, and crustaceans. In simple words, the statolith shifts as the animal moves.
What is statocyst Class 11?
Hint: The statocyst is a balanced sensory receptor. It is present in some aquatic invertebrates, including molluscs, bivalves, cnidarians, ctenophores, echinoderms, cephalopods, and crustaceans.
