A recovered virally-infected Angel Comb

Above is what it looks like while infected, infecting nearby juvenile Angel Comb. This main comb cannot recover until the juveniles it is connected to have their infection ousted.

This is what the Angel Comb looks like once it has recovered.

This animal (Cecidia gamikos) has no Earthly analog. No apparent ecological niche except to reproduce and release virus. The ancestral firm may be a ctenophore (comb jelly).

Its core is a viral incubator stocked with genetic material from organisms in the surrounding ecosystem.

[1] Complete viral saturation*
The bloom core's entire body is densely infected with large RNA virus (generated name: Proteavirus beta). The only exception is the central bulb.

[2] External food supply**
The core's filter combs are inactive. It receives all its calories from the titan rockbore below, or, if that supply is disrupted, from nearby bloom cankers. Cutting off both food supplies might allow the bloom core to clear its infection.

[3] Living bioreactor
The central bulb of the core contains genetic sequences from organisms living in the nearby ecosystem. These sequences are used as training material for Proteavirus beta to improve its infectiveness. It is a laboratory for genetic adaptation.

Assessment: source of virus for all nearby bloom nodes. Starve and purge viral infection by clearing connected nodes and cankers. Retrieve central bulb for genetic research and adaptation. Further investigation urgently required. Does this organism have a function beyond viral propagation?

Note: users may be curious about the symbiosis between Earthly parasitic wasps and polydnaviruses. The wasp's own genome contains the viral genome, allowing the wasp to create the virus for use in its reproductive cycle.

It acts like any other Angel Comb once recovered and you may touch it to gain an adaptation for better ocean life/exploration.
