Worms:
Acoel flatworms, Waminoa sp., are a small invertebrate resembling flatworms. The animals lack a gut; the mouth opens directly into the interior body tissue.
Polyclad flatworms are hermaphroditic. Some species engage in "penis fencing", attempting to impregnate each other. Bearing young is metabolically expensive for these animals.
Yellow papillae flatworm, Thysanozoon nigropapilosum

Persian carpet flatworm, Pseudobiceros bedfordi
Flowers' flatworm, Pseudobiceros cf. flowersi
Calcareous tube worms are worm-like sessile invertebrates that anchor their tails to a substrate and secrete mineral tubes around their bodies into which the whole animal can withdraw.
