1) Hydra mainly feed on aquatic invertebrates such as Daphnia and Cyclops. When feeding, Hydra extend their body to maximum length and then slowly extend their tentacles. Upon contact, nematocysts on the tentacle fire into the prey, and the tentacle itself coils around the prey.
2) In order obtain food, sponges pass water through their bodies in a process known as filter-feeding. Water is drawn into the sponge through tiny holes called incurrent pores.
