Baby ducks eat mostly invertebrates for the first few weeks of their lives, including insects, worms, snails and crustaceans. They need a huge amount of high-protein food for these first few weeks, and as soon as the ducklings hatch, the mother will usually take them to wherever there is the most food.Know More
As they are born with part of the egg yolk still inside them in an egg sack, baby ducks can survive for approximately the first three days of life without eating. Ducks mature incredibly quickly, so by the time they are two or three weeks old, they will already begin eating like normal adult ducks. For some species, this means switching over to eating primarily plants or possibly nuts and seeds.
Domesticated ducklings also have the same high fat and protein nutritional requirements as their wild counterparts. However, they are usually supplied this in the form of specialized duckling food that can be found in pet stores. It is also possible to feed them food designed for baby chickens, but it's necessary to increase the niacin content of this food, such as with brewer's yeast. Some people also recommend slowly adding oats to their diet as well.
Ducks require bits of rock and dirt in their stomach to properly digest food, so it's also important to take a small amount of gritty dirt or buy chick grit and mix this into the duckling's food.Learn more about Waterfowl
Lobsters eat fish, worms, mollusks, other crustaceans, plants, sea urchins and snails. They are omnivores, meaning they consume both plant and animal life. Lobsters prefer to hunt and eat live prey but do scour the ocean floor for dead sea creatures when necessary. Some deep-sea lobsters scavenge for large, dead animals such as whales.Full Answer >
Depending on the species, some sea worms eat crabs, other worms, snails, crustaceans and fish, while some are parasites that eat crab eggs or anything that can be scavenged from a host. The ribbon worm lives in the sandy seafloor and covers its prey with a toxic slime, paralyzing it.Full Answer >
Different species of echinoderms eat a variety of different foods, from ocean plants to smaller sea creatures such as snails, worms, and crustaceans. Some species also scavenge dead plant and animal matter on the ocean floor.Full Answer >
Shore crabs feed primarily on invertebrates such as molluscs, clams, crustaceans and worms, but they eat practically anything they can get a hold of, including the remains of dead organisms. Their voracious appetites have lead to the regional decline of several species. Shore crabs are an invasive species due to their easily accomodated diets and widespread dispersion.Full Answer >
