White, tan, brownish-orange, or similar colors are the colors of the column. Their tentacles can be greyish or whitish. A white ring is sometimes located around their mouth. Their oral disks are well muscled. Small zooplankton, and small scraps of fish is what they feed on.
Asexual reproduction occurs by fragmentation of the basal disk, or by pulling itself into two parts.
This is known as laceration. Sexual reproduction occurs by releasing the sperm and eggs through their mouth into their environment. Their mouth is also their anus. We are feeding M. senile zooplankton through a turkey baster. The tentacles are bringing the zoopankton into the anemones' gastrovascular cavity.
