Anti predator adaptations exhibited by holuthuroid echinoderms include: Group of answer choices Pearl fish symbionts Cuvierian tubules evisceration spine-shaped ossicles

a japanese spider crab is an invertebrate, explain the mechanism of their protective structure. provide scientific explanation   please do not just copy from google

Echinodermata is the first phylum you have examined whose members possess true endoskeletons. What are some advantages that an endoskeleton provides?

a marine blue crab has ten pairs of jointed appendages, which include large claws called chelipeds to capture food, and eight walking appendages. Notice the differences in the structure of these 8 pairs. Compare the structures present in the first 3 pairs (modified as maxillipeds), and the last five pairs. What do you think are the main functions of the last five pairs? Crustaceans have biramous appendages. What structures are present only in the first pair? In the last pair? What do you think are the function of these structures?

Create a concept map or an illustration drawing for each phylum (annelida, Platyhelminthes, nemotod, echinoderms, chordata) that will help you classify invertebrate animals into that group

Key out the animal represented to the class level by the photo below using the dichotomous key attached. You must use this format: 1, 2, 7, 8... - BE SURE TO PLACE ONE SPACE AFTER THE COMMA AND BEFORE THE NEXT NUMBER AS SHOWN! DO NOT PROVIDE THE UNDERLINED NAME HERE!

In planarians ampulation : can planarians regenerate any body part?

In echinoderms, the main coelomic compartment is completely converted into the water-vascular system. restricted to a small space around the gonads. the pyloric stomach. O missing. a somatocoel.

Arthropods are known for displaying "tagmosis", which means that arthropods have tagma. The tagma of arthropods; Are the jointed appendages on the thorax Are the wings which are outgrowths of the exoskeleton Are fused body segments that are specialized for certain functions Are the specialized mouthparts they use to feed
