Ctenophores such as this one look similar to jellyfish but have 8 rows of fused cilia (ctenes) along their sides which beat for propulsion. Pleurobrachia bachei is elliptical in shape with no large lobes. The comb rows (ctenes) are nearly equally spaced and extend nearly the entire length of the body. Two long (up to 15 cm), branched tentacles trail back from sheaths which angle out from near the gut toward the aboral pole (photo). The tentacle branches (tentillae) are abundant (photo), are only from one side of the tentacle, and are not coiled (though the tentacles can be retracted into the sheaths). The animal is clear, but organs and tentacles may be pink, yellow, white, or orange-brown. There may be purplish blotches near the pharynx. Diameter to 1.5 cm; length slightly longer than diameter.
