  2. Cilia for filter feeding

  3. Teeth for crushing

  4. Teeth for filtering

A Correct answer
Explanation

The tentacles of Ctenophores have meridonial bands with transversely arranged combs like structures. Comb-like eight ciliary plates on the body serve the purpose of locomotion. 

So, the correct answer is 'Cilia for locomotion'.

Multiple choice zoology animal diversity - i (inverterbrate phyla) ctenophora phylum ctenophora cnidaria

Tentacles of ctenophores contain

  1. Cnidoblasts

  2. Colloblasts

  3. Digestive glands

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ctenophores use their tentacles to capture their prey and these tentacles are made of specialized cells called colloblast. These colloblast are made of axial filaments and a granular sticky dome.

So. the correct answer is 'Colloblasts'.

C Correct answer
Explanation

The correct matching is: Ctenophora-Pleurobrachia-bioluminescence, Platyhelminthes-Planaria-acoelomate, Cyclostomata-Hog fishes-migration, Aschelminthes-Ancylostoma-endoparasite, Echinodermata-Ophiura-coelomate. This follows taxonomic classification and characteristic traits.

Multiple choice zoology animal diversity - i (inverterbrate phyla) ctenophora phylum ctenophora cnidaria

Select the correct one(s) for Ctenophora -

  1. They have similarities with Cnidaria

  2. They have 8 external rows of ciliated comb plates for locomotion

  3. Bioluminescene

  4. All
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Ctenophores, variously known as comb jellies, sea gooseberries, sea walnuts, or Venus's girdles, are voracious predators. Unlike cnidarians, with which they share several superficial similarities, they lack stinging cells. They have ciliated comb plates for locomotion and exhibit bioluminescence
So, the correct option is 'All'
Multiple choice zoology animal diversity - i (inverterbrate phyla) ctenophora phylum ctenophora cnidaria

Comb jelles or sea walnuts are placed under -

  1. Cnidaria

  2. Ctenophora

  3. Echinodermata

  4. Annelida

B Correct answer
Explanation
Ctenophores, variously known as comb jellies, sea gooseberries, sea walnuts, or Venus's girdles, are voracious predators. Unlike cnidarians, with which they share several superficial similarities, they lack stinging cells.
So, the correct option is 'Ctenophora'
Multiple choice zoology animal diversity - i (inverterbrate phyla) ctenophora phylum ctenophora cnidaria

Find out the odd one.

  1. Adamsia

  2. Astraea

  3. Physalia

  4. Pleurobrachia
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Adamsia, Astraea and Physalia belong to the phylum Cnidaria (Coelenterata). Cnidarians are aquatic, mostly marine, solitary or colonial sessile or free swimming, radially symmetrical animals. These phyla are divided into three classes Hydrozoa, Scyphozoa, and Anthozoa. Pleurobrachia belongs to the phylum Ctenophora.

So the correct answer is 'Pleurobrachia'.
