Traits

Long tapering feelers that are highly flexible.

Tentacle feelers can grow numerously in a flat array, appearing as a mantle.
The tentacles can have suckers along their undersides; those without suckers are used to detect movement in deep water.

Note: They should be visibly smaller and thinner than a basic tail. Bunches of feelers cannot occur from one point in groups of more than three.
Deviations of these (i.e extremely long, thick, or bunched feelers) will require the clustered feelers upgrade.
