Traits

Jellyfish tendrils and a soft, jelly-like "hat" on the head. These tentacles are not prehensile and cannot move on their own; instead, they rest like hair would. Can be venemous.

Squid-like  pointed"hat" and 8-10 squid arms and 2 tentacles. Tentacles stand out by being wide with suckers at the end, while squid arms are generally shorter, thinner, and taper off at the end.

Cuttlefish-like pointed "hat" with 6-10 short arms, may have 2 tentacles.

A shelled "hat" with shorter tentacles emerging from it. Can have up to 90 thin tentacles - though it can have much less than that for the sake of stylization.

Octopus tentacles/octopus arms emerge from the head - may have 6-10 tentacles, but 8 is the most common amount.

An upward shaped beak that curves into a point.

A beak that points forward, longer than usual Nauticava beaks. Highly efficient for fishing.

A beak that points downwards, more resmniscient of bird beaks.

A thicker beak, efficient in breaking open shells of marine prey.

Fleshy whiskers like that of a catfish's barbels. Any number of them can be present on a Nauticava's head. May not have suckers or mimix extra tentacles.

Adds scales or plating to a Nauticava. It can be applied to the body, limbs, or the head/mantle. This may not give a Nauticava segmented or robotic-looking limbs.

Fins that resemble those on the Seraph tail; they can be located on the back or any other part of the body, and can be more than one pair.

Hands that don't have any claws on them, or have missing claws.

Hands that feature no webbing to them. Makes swimming with hands less efficient, but makes hands more flexible on dry land. This can also apply to feet.

A large, hooked claw for spearing food - this can be trimmed or clipped, but will always grow longer than the others. Can apply to one claw or to all of them.

A standard webbed, clawed hand type.

An extra prehensile limb in the form of a tail. Can be short or long, but may not surpass the length of the body from head to toe.

A short, nub tail. May have suckers like a tentacle, or be simple and featureless.

A curled, armored tail that resembles a seahorse's tail. Can be prehensile.

A tail that resembles a shark's, long with sharpened fins.
