Mollusks mhuka dzesingaite musana dzinoonekwa nekuve nemuviri wakapfava une tsoka yemhasuru yakafukidzwa necalcium-based exoskeleton kana ganda. Kazhinji mhuka dzemumvura.

Mhando dzeemollusks

Kune makirasi matatu akasiyana kana mhando dzemahollops:

• Gastropods. Hozhwa uye slugs. Vanenge makumi masere muzana emamollusk ndeaya ekirasi iyi.
• Cephalopods. Octopus, squid uye cuttlefish. Iri iboka risinganyanyo kuwanda asi rakanyanya kushanduka.
• Vivalves. Muboka iri mune mafiramu, mussels uye maoysters. Hunhu hwechikamu chidiki ndechekuti ndivo chete vevatatu madiki vasina radula. Kupomba, mussels uye maoyster. Ivo chete ndivo vasina radula.

Morphology

• Kufuridzira system. Mollusks mazhinji anofema nemumakonzo, kunyange hazvo mamwe marudzi akagadzira mweya wekufema.
• Kugaya chirongwa. Mollusks anofudza kuburikidza nenhengo inonzi radula iyo yakaumbwa serurimi. Ichi chinodaidzwawo kunzi nguvo, nhengo iyi inovhara vhoriyamu uye mune mamwe marudzi anoviga calcium carbonate kuti igadzire ganda.
• Kutenderera system. Vane moyo, aorta, uye tsinga dzeropa.
• Kubereka hurongwa. Mollusks ane oviparous, ndiko kuti, ivo vanobereka nekuisa mazai neechikadzi. Maitiro avo akasurukirwa, hazviwanzo kuvaona vari mumapoka, kunze kwekunge vari kusangana. Mollusks mazhinji ari hermaphrodites.

Kudyisa

Mhando yekudyisa mamollusks inosiyana zvichienderana nemhando imwe neimwe. Kazhinji, mollusks epasi anodya mhuka dzinodya mhuka, nepo mhuka dzemumvura dzinodya nyama, kunyange hazvo vachisimbisa kudya kwavo paplankton uye algae.

Habitat

Nezvekugara kwavo, mollusks dzinogona kugara pasi pemvura, pasi pegungwa (zvinoumba 23% yezvipuka zvese zvegungwa uye zvemvura yakachena), asi ivo vanogona zvakare kujairira uye kugara 3,000 metres pamusoro pegungwa pasi.
