Open type blood vascular system is found in
1 earthworm
2 lizard
3 cockroach
4 toad
Explanation:
(c) Open type blood vascular system is a type of circulatory system in which nutrients and waste are moved through the body with the help of a fluid which flows freely through the body cavity, rather than being contained in veins. Many invertebrates like insects (eg, cockroach) and shellfish have an open circulatory system, with the exact composition of the circulating fluid varying, depending on the animal species involved.
