In which among the following animals, retrogressive metamorphosis is found?
1 Vertebrata
2 Urochordata
3 Invertebrates
4 Chordates
Explanation:
B Urochordata possesses a unique feature called retrogressive metamorphosis. In this type of metamorphosis, an active larva metamorphoses into a sedentary (adult) phase. - Metamorphosis is the phenomena in which there are converts which transform the organism from its juvenile stage (initial stage) to adult stage (end stage). - They belong to the group of Urochordates also known as Tunicates. - Tunic is a compound which form protective covering and animals are called tunicate. Tunic is produce by tunicates which are similar to cellulose which contain the cellulose micro fibrils. E.g. Herdmania.

Pick up the organism that emits light
1 Pyrosoma
2 Mytilus
3 Pontobdella
4 Aplysia
Explanation:
A Pyrosomes is the organism that emits light. It is capable of bioluminescence, a phenomenon where it produces and emits light. This ability to glow is a fascinating aspect of pyrosoma's biology.

At retrogressive metamorphosis the uro chordate larva
1 loss of notochord
2 loss of tail
3 experience reduction of nervous system to a visceral ganglion
4 all of the above
Explanation:
D Retrogressive metamorphosis in urochordate larvae involves the loss of the notochord, loss of the tail and reduction of the nervous system to a visceral ganglion. This process leads to a simpler anatomical structure as the larva matures into an adult form.

Mode of feeding in tunicates is :
1 acrophagus
2 parasitic
3 ciliary
4 myxotrophic
Explanation:
C The mode of feeding in tunicates are ciliary or filter type. Tunicates are suspension feeders, means they feed by filtering plankton and other small food particles from the water. They are commonly known as sea squirt.

Outer covering of tunicates is formed by :
1 tunicin
2 cellulose
3 chitin
4 all of these
Explanation:
A The outer leathery covering in tunicates is formed of cellulose like substance called tunicin. It acts as exoskeleton. The body covered by the test it formed by tunicin. It protects from predators like sea star snail and fishes.
