What is a rostrum?

We have said earlier that L. plumosus have a beak like long “rorstrum”. A rostrum is a beak like body part. Many animals have them like Bottlenose Dolphins, Weevils, many types of bugs etc. In case of shrimps, the rostrum is nothing but an extension of their carapace or head shield.

What is the difference between a shrimp and a lobster?

Shrimps and Lobsters are closely related aqua animals. Anybody can guess that from the similarity of their shape. Shrimps can be found in both fresh and salt water bodies but almost all of the lobster species are marine dwellers. Another importance difference is size. Lobsters are considerably bigger in size than the shrimps. Shrimps are swimmers but lobsters are bottom crawlers. The pregnant shrimps carry the eggs inside their body but lobsters are not known for such behaviors.

Where do Donald Duck Shrimps live?

They are small marine animals. But they do not live everywhere in the oceans. They are very localized creatures. Till date, these shrimps are only located in the shallow coral reef areas of the Maldives islands. 

Why the Plume Shrimp is called as a “Crustacean”?
