Animals not belonging to any of the others groups are placed in this category. This includes animals groups such as corals, echinoderms, gastropods and more.


Species list:

deep sea coralsDeep Sea Corals

Although at great depths, sometimes more than 1,000 meter down, the ocean floor still contains a variety of life. Even different types of corals are often found, many with beautiful and complex structures.



Echinoderms are a large group of animals found at all depths. The name is derived from Greek and means “spiny skin”. The group has great biological importance and has an active role in many marine functions.

  • There are about 7,000 described living species belonging to this group.



Sometimes different kinds of eggs are also a part of the catch. They are often impossible to identify.



Gastropods a group of animals that are more commonly known as snails and slugs. They inhabit almost every part of the world both terrestrial and aquatic, and a vast range of ecological niches.

  • There are 60,000 to 80,000 living species of gastropods making it the second largest taxonomic class in the world.



Polychaetes are a class of annelid worms, generally marine, with segmented bodies. They are sometimes referred to as bristle worms. They can be found all over at any depth and have even been found at the world deepest place, the bottom of the Challanger Deep (10,911 metres down).

  • There are more than 10,000 described living species belonging to this group.



Siphonophores (Eschscholtz, 1829) belong to the phylum Cnidarians and are a class of marine invertebrates. They form super colonies which sometimes can resemble jellyfish. Although it might seem like one organism the colonies are formed by many distinct looking organism individuals. Some of the most famous members of this group are the Portuguese Man o' War (Physalia physalis) and Praya dubia, one of the largest animals in the world (40-50 m).

  • There are about 175 described living species of Siphonophores.

We have come across this organism a number of times, but, are still not certain if it really is a Siphonophore. But that is our best guess. Nevertheless did it fascinate us with its ability to completely disappear when put in water.
