Question

Haemocoel is found in____________.

Answer 1

Hemocoel:

1. Arthropods and Mollusca have a blood-filled bodily chamber called a hemocoel.
2. The hemocoel is an enlarged blastocoel that shrinks the coelom significantly.

Phylum Arthropods:

1. Arthropods have symmetrical bodies on both sides.
2. The body of these animals is divided into three segments: head, thorax, and belly.
3. They have appendages with joints that aid in locomotion.
4. Haemocoel, white-colored blood, fills the bodily cavity.
5. The exoskeleton is a rigid structure consisting of chitin, a complex polysaccharide.

Phylum Mollusca:

1. They range in size from massive squids and clams to tiny one-millimeter snails.
2. They have two radula and mantle characters that aren't found anywhere else.
3. Coelomates, triploblastic body, soft, unsegmented, bilateral symmetrical (except in Monoplacophora).
4. Tissue-systems organization is superior.
5. The head, foot, mantle, and visceral mass are all body parts.
6. Body composed of chitin, a complex sugar.

Therefore, Haemocoel is found in Phylum Arthropods and Mollusca.
