Yes it's a sessile.
hydras
As juveniles. As adults, hydra become sessile and fasten to rocks. "Nekton" are creatures that swim, like fish.
No a Hydra is non a pseudocoelmate, acoelomate, or eucoelomate. The basic body plan is a sac with central digestive compartment, the gastrovascular cavity. A single opening functions as mouth and anus. There are 2 variations on this body plan: the sessile polyp and the motile medusa
Benthic means bottom dwelling, and sessile means non-moving.
they are sessile
Fungi are non motile means they are not able to move.
The two forms of Cnidarians are the Medusoid or mobile form (e.g. Hydra), and the Polyp or sessile form (e.g. Aurelia).
All Cnidarians are mobile at some point in their lifetime. For most, it is in the larval stage. Jellyfish start out as mobile larva, then become sessile, then become the mobile jellyfish you are familiar with. Others, like corals, start out as mobile larva, settle down and remain sessile for the rest of their adult life. As adults, hydra can be mobile or sessile, as they choose, but they don't swim far.
no there is only one hydra armor ans its member nanana lol
most people believe that plantae are motile
Since they're sessile (fixed in place), they can't very well chase their prey so they have to wait until it comes close to them. That's the nature of ambush.
Hydras can commonly be found in freshwater lakes, and some species can live in saltwater environments. They are usually found near the shore as most species are sessile and live their life attached to rocks.
