Option B: Sea squirt
Option C: Sea potato
Option D: Both B and C

Answer 1

Hint: Herdmania is found in marine habitat and it is a ciliary feeder. It is brownish in colour. Herdmania comes under Kingdom Animalia in the family of Pyuridae .

Complete answer: Herdmania is a genus of ascidian tunicates in the family of Pyuridae.
Herdmania momus is the most commonly found species of ascidians.

Option A- Sea purse: It is the egg case of skates and some sharks it has a quadrangular outline. From these outlines filaments are produced that attach to the sea weeds. It contains one embryo or egg commonly. Thus, this is not the correct option.

Option B- Sea squirt: It is also known as ascidian. These are marine animals having few features of vertebrates. Some species live individually while others live in groups or colonies. As we discussed above herdmania also belongs to genus ascidian so this option is related to our questions’s statement.

Option C- Sea potato: Also known as Echinocardium cordatum. It is sea urchin from the family Loveniidae. It is found buried in the sea floor in temperate seas around the world.

Option D- Both B and C: option B and C creatures don't belong to the same family group and are characteristically different marine animals.

So our correct answer is Option B – Sea squirt.

Note: Herdmania is called a sea squirt because they have the capability to eject out or squirt out water when they are removed from their watery home. In such situations it suddenly contracts its body and with full force ejects out its inner contents and for this reason they are known as sea squirts.
