Tunicates are preyed upon by various predators such as sea slugs, sea stars, fish, and some species of marine birds. Additionally, some species of sea urchins and sea turtles also feed on tunicates.
Deuterostomes that show radial symmetry in their adult form called phylum Echinodermata. Phylum Echinodermata are things like sea stars, sea urchins and sea cucumbers.

Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Non-vertebrate chordates are those animals that have a notochord but no true backbone. There are two groups known as the tunicates and lancelets. Tunicates include sea squirts and salps. Lancelets are a group of burrowing filter feeders that live on the ocean floor.
Tunicates (Because it has a covering called a Tunic)
Tunicates, (Sea squirts, Sea tulips) should adequately meet your desire for strange!
The common name for subphylum Urochordata is tunicates or sea squirts. These marine animals are characterized by their cylindrical bodies encased in a tough tunic made of cellulose.

There are actually four major classes of echinoderms. These are Crinoidea, Asteroidea, Ophiuroidea, Eichionidea, Holothuroidea, and Concentricyloidea. The animals in these range from sea lilies to sea urchins.
There are over 6000 types of echinoderms. A few examples are the banded-arm brittle star, common sea urchin, cushion sea star, etc. I you were looking for types of echinoderms, they areSea star or starfish (Asteroidea)Brittle stars, basket stars, serpent stars (Ophiuroidea)Sea urchins, heart urchins and sand dollars (Echinoidea)Holothurians or sea cucumbers (Holothuroidea)Feather stars and sea lilies (Crinoidea).
Animals in which the anus develops before the mouth belong to a group called deuterostomes. Examples include echinoderms (such as starfish and sea urchins) and chordates (which include vertebrates like humans). During early embryonic development in deuterostomes, the blastopore develops into the anus first, with the mouth forming later.
