Worms And Their Habitats

A worm is an animal that can be found in the water. There are different species of worms you’ll find in water. Scientists have spent years studying worms and their evolution. Of all the worms on earth, the marine worm accounts for nearly 98% of all.

This makes it crucial to study the marine worms. These worms can be found across six phyla. This includes Phoronida, Hemichordata, Annelida, Nematoda, among others. When you consider the number of worm species within a phylum, you’ll realise how enormous these animals are. Within Annelida, there are over 800 species.

Worms also come in different sizes. While the largest have been seen to be about 180 feet, there have been those with far less sizes. They also come in different shapes. Just like some other animals with different shapes and sizes, worms are also not excluded from the equation.

A careful study of these animals will reflect that they take different sizes based on the species. Since there are thousands of species, it can be expected that the animals will come in various shapes and sizes. There have also been small worms that have been recorded.

The smallest has been a nematode and it’s microscopic. The thickness is also like that of a paper. There is a high diversity level when it comes to the shape. While some are flat, some others are like a ring in shape, while some others might be round.

Marine worms are spread across the world. They can be found across various seas. From deep seas to reefs to salt marshes, these animals have a vast habitat structure such that you can find them across a wide range of places. If you’re looking to examine worms or you’re researching and you need to get marine worms, you can locate them by going to a sea and looking within.

They also burrow themselves in algae, mud and sand. You can also locate them under rocks. There are certain species with a colonial nature. That is, they move together and love dominance. For these kinds, you’ll often find them together. You can get over a 100 clogged together in one place. Others that are not built this way are solitary. They are often alone and they burrow themselves in the sand or mud.

These worms have different kinds of lifestyle. There are some species that have an active lifestyle in that they swim across the sea and they leave their habitats to explore other places. These species can be found even far away from the mud or sand where they regularly burrow themselves. When they are not swimming, they can be on the seafloor foraging along.

On the flipside, there are some other species that build the mud up to burrow themselves. For these species, they spend most of their time in that particular space without leaving. This goes to show that there are different lifestyle approaches from these worms. Marine worms that are parasitic in nature will exhaust the bulk of their time on the host.
