Planarian auricular processes function as the sense of touch and smell

No, it's taste and smell.

1. Planarians are widely distributed, most of them are freshwater species, and some live in seawater, land or parasitism. The body is leaf-shaped, soft and ciliated. The head is spade-shaped, has two eyes, but cannot see, is sensitive to light, and sometimes has tentacles.

Tail tip. The mouth is posterior to the ventral surface, often in the posterior part of the body1 3. No body cavity.

The pharynx can protrude from the mouth and swallow the intestine, which is a blind tube. The body length is generally about 3 15 cm (in) and some exceed 30 cm (about 1 ft).

2. Planarians live in fresh water, often adsorbed to stones, do not move much, and do not like sunlight. Planarians often hide under rocks or leaves at the bottom of the water, and can easily be found in streams where the current is not fast and there is abundant organic matter upstream. For example, a stream bypasses a small village, feeds into a pond and flows a short distance downstream, turning over rocks or leaves at the bottom of the stream, often to find planarians.

The planarian insects feed on small animals and organic matter in the soil, and are nicknamed earthworm killers, which should not bite people. It is a relatively inferior animal that has not been found to be harmful to humans.

1) The body of planarians is about 1 cm long, dorsoventrally flattened, shaped like willow leaves, the front end is triangular, and there is an ear process on each side, which has the effect of perceiving taste and smell There are two eyespots on the back of the head, which can distinguish the intensity of light Planarians are the representative of the canonical paw of the planarian hood, the body of the planarian is dorsoventrally flattened, shaped like a willow leaf, and its body is symmetrical on both sides.

Platizoa phylum Planarians planarians planarians.

The body is soft, flattened and leaf-like, slightly convex on the back, brownish, light on the ventral surface, the anterior head is triangular, with well-developed ear processes on each side, and the sense of touch and smell is subtle, and there are two black eyespots on the back of the head, which can perceive dark light.

Wouldn't this also be meat reishi, hehe! Can't tell.

<> solution: The body of planarians is about 1 cm long, dorsal and ventral flattened, shaped like willow leaves, the front end is triangular, and there is an ear process on each side, which has the effect of perceiving taste and smell There are two eyespots on the back of the head, which can distinguish the intensity of light Therefore, planarians are flattened animals, and the body shape of planarians is characterized by flat dorsal and ventral, and the left and right sides are symmetrical As shown in Fig:

Therefore, c

Fish in the ditch and put it in the fish tank, find some aquatic weeds and throw them in, ask the nearby aquarists who have a few in the fish tank, and go to the flower and bird market to sell live bloodworms.

That's the larvae of mosquitoes, your fish tank is an ordinary fish tank, it's almost winter, and it's going to be gone soon.

People want to get rid of you, but they want to.

1. Planarian eggs in the ADA mud.

2. Tap water may carry insect eggs.

3. When buying aquatic plants, you may also bring insect eggs.

Basically everyone who raises grass tanks will have this worm.
