Yes. They have extensive cephalization. They have a brain and eyes.
MATBE
Tape worm like lung fluke and liver fluke
platehelminthes (flat worms)
Tape worm like lung fluke and liver fluke
Worms are hermaphroditic, so no, they do not exhibit homosexual behavior or heterosexual behavior.
cephalization for segmented worms, but idk about anything else
Yes, frogs exhibit bilateral symmetry. Cephalization is the concentration of nervous tissue at one end of an organism. The frog has this nervous tissue (the brain) at the anterior end of the body (the head.)
Phylum Nematoda does exhibit cephalization. Cephalization is a evolutionary trend in development in which the sensory and neural organs of a species becomes concentrated on one end of an organism.
Segmented worms, known as annelids, have bodies made up of repeated segments. They include common earthworms and marine bristle worms. Annelids have a true coelom and exhibit a high level of cephalization, with a well-developed nervous system and sensory organs. They play important roles in ecosystems by improving soil health and serving as food sources for other organisms.
An earth worm demonstrate cephalization through an an enlarged ganglion that acts as a simple brain. One particular part of the earth worms nervous system, an enlarged ganglion, does act as a simple brain, and it is located in the anterior portion of the earthworm's anatomy. Hence, the earthworm exhibits cephalization.
