Lophotrochozoans - Study guides, Class notes & Summaries

Invertebrates️️Animals without a backbone. About 95% of known animal species. Calcarea and Silicea️️phylum that includes sponges; no symmetry, tissues, body cavity, organs, nervous system; basal animals; mostly marine; contain spicules; most are hermaphrodites; free-swimming during larval stage and sessile (non motile) as adults; suspension/filter feeders Suspention feeders️️small and large organisms that use filtering and trapping techniques to collect minute food particles su...

I have color coded and organized the groups of animals into protostomes, deuterostomes, and the phylum within along with important characteristics. There is also information on thermoregulation within the animals and maintaining homeostasis.

This is my study guide for my upcoming biology exam, all about animals. It briefly goes over all topics we have covered in these last few weeks of class, including the topics surrounding animal development, the Cambrian explosion, Porifera and cnidaria, neurons and sensory mechanisms in animals, triploblastic development, muscles, Lophotrochozoans, Deuterostomes, circulation in animals, gas exchange, the Gnathostomes, tetrapods and amniotes, and mammals. I hope you enjoy my notes!
