How does the mollusks reproduce?

Answer 1

Bivalves don't reproduce like humans or most mammals do. They reproduce by releasing sperm and eggs into the water. The sperm and eggs then fertilize and once fertilized the eggs then float to the surface.

Answer 2

Reproduction in mollusks can be sexual depending on the classes of mollusks. One of the most interesting reproductive characteristics is the reproduction of bivalves (mussels or clams). Mussels have 2 separate sexes, (both having male and female sexes) and they are called hermaphrodites. These bivalves reproduce by releasing eggs and fertilization happens externally. The sperm in the water fertilizes these eggs forming a plank tonic larval stage.

The spawning varies depending on the temperature and is usually happens from April to November and after being hatched in time the swim freely and after several weeks these larvae settle to the sea bed as a mature mollusk.

In some other species like the "prosobranch" snail, both have 2 sexes and reproduction occurs by spraying the eggs and sperm into the water but fertilization may happen or not and it's a matter of chance.

How do organisms in the phylum mollusca reproduce is unique and during the ejection of eggs and sperm cells into the water there is some form of chemical agents that stimulate other mussels to spawn or generate their sperms and eggs.

Fresh water mussels are quite different that the sea mussels as the larval stage lives parasitically within fish's tissues, gills or fins for about 2 weeks until they detach, and independently live on their own and sink down to settle to the substrate. This behavior of reproduction is one of the strategies for mussels to spread their larvae in order to colonize new mussel beds.

How do organisms in the phylum mollusca reproduce? Reproduction for other classes of molluscan can be sexual and this happens to snails. Common land snails are also hermaphroditic. They have both male and female reproductive organs snails and can mate mutually but still they prefer find another snail to mate with. Mating happens also during some particular time and temperature and usually during late spring or early summer. One snail stabs the skin of the other snail with what they call a calcified 'love dart' to stimulate the other snail and the sperm is transferred or exchanged from one to another sexual partner. Female snail will then produce eggs internally and then fertilized by the sperm that has been exchanged. It takes around 1 month for the snail to lay eggs, 14 days to hatch and 2 years fro the baby snails to become mature.

How do organisms in the phylum mollusca reproduce? The reproduction the squid starts when a male squid produces a special arm called a hectocotylus that transfers male sperm to the female squid through her pallial cavity. Once fertilized the female later lays a number of eggs that will hatch into a small squid larvae. The cephalopods are highly protective of their young ones. They cook care of them by cleaning, feeding and defending them from the attackers or threat of danger to the extent that female squid could die because they can't defend it self because they are too weak

Answer 3

Barnacles tend to live in shallow waters of the ocean. They usually latch themselves onto whales or boats and feed on the bacteria or algae that collects.

Answer 4

Mollusks reproduce sexually. Some are hermaphrodites, but still reproduce sexually. All of them lay eggs once they are fertilized.

Answer 5

Barnacles have adapted to be able to attach themselves to other animals or surfaces. They also have a hard shell to protect their bodies.

Answer 6

they rebuild it (great answer!)

Answer 7

well i dont know
