Sea stars don't have acirculatory systemlike we do. They have a water vascular system. This is a system of canals in which seawater, instead of blood, circulates throughout the sea star's body. Water is drawn into the sea star's body through themadreporite, which is shown in the nex...
oyster) and worms by pulling the food apart with tube feet and turning stomach inside out, into the food. Digestive enzymes are then secreted onto the food item and pulled back inside the sea star body partially digested. Mouth of the sea urchin is called an Aristotle’s Lantern...
Echinoderms can also reproduce asexually by regenerating body parts, such as arms and spines. Sea stars are well-known for their ability to regenerate arms that are lost. In fact, even if the sea star has only a small part of its central disk left, it can grow an entirely new sea star...

made of fused skeletal plates and marked by regularly arranged tubercles to which the movable spines are attached. Five rows of the skeletal plates are pierced by pores for the tube feet of the water-vascular system; these are typical of echinoderms and are used for locomotion. The mouth is...

Furthermore, we propose that this simple nutrient transport system formed a framework for the evolution of intricate ECM-based circulatory systems, ensuring a systemic nutrient supply in increasingly large and complex bilaterians.

The presence of adult flukes in the circulatory system of infected animals and the embolization of eggs through host vessels leads to lesions of varying severity, including arteritis, thrombosis, aneurysms of the great vessels and disseminated granulomas in all body districts [1,2,3]. Six genera...
‘cryptometamorphosis’, occurs with a dramatic reorganisation of its digestive system where the oesophageal gland is greatly enlarged while the other parts of the digestive system effectively stop growing21. Thus, these two genera have evolved an endosymbiotic lifestyle independently and convergently, ...
