Biology

PLATHELMINTHES, NEMATODES AND ANNELIDS

Álvaro Martínez 1ºB Jose. M Cantos 1ºB Aitor Cruzado 1ºC Pedro Megías 1ºC Iván Perez 1ºC

They have bilateral symmetry.

They tend to live in humid enviroments.

They don´t have articulated appendages, such as legs or antennae.

Common characteristics

Did you know... There are 20,000 types of worms

PLATYHELMINTHES

Platyhelminthes are simplest animals that have cephalisation. There are two groups: tapeworms and planarians and they are parasites.

Did you know that... worms improve the structure of soils

Planarians

Tapeworms

INTERACTION

nutrition

Tapeworms

Planarians

Their digestive cavity has only one orifice. It functions as both the mouth and anus.

Some have hooks and suckers to anchor themselves to the lost

They absorb nutrients from the animal´s intestine.

They have eye spots that can detect changes intesity of light.

They are sexual and asexual.Sexual planarians are hermaphrodites.Asexual planarians can be cut into pieces and this pieces can be regenerate.

PLANARIANS

TAPEWORMS

Reproduction

They are hermaphrodite and they can self-fertilisation and cross-fertilisation.

NEMATODES

Nematodes are roundworms that don´t have segmented bodies. Some are parasites and some of them are free-living. Pinworms, whipworms and heartworms are parasitic nematodes.

They usually reproduce sexually.Female lay eggs inside the host and they are released in the host´s excrement.

They have sense organs and some adults have hooks or teeth at the head end sob they can attact to the tissue of the host.

Food travels from the mouth directly to the intestine and out of the anus.

NEMATODES

NUTRITION

INTERACTION

REPRODUCTION

Annelids have cylindrical bodies that are divided into segments, called metameres.Annelids live in aquatic enviroments and in moist lands enviroments.

ANNELIDS

Nutrition

Interaction

Reproduction

The majority reproduce sexually. Some are hermaprodite (self-fertilisation). Generally an individual mates with another to reproduce (cross-fertilisation).

They have hard hairs on their skin, called setae, to help them move.

Annelids have a digestive tube with a mouth and an anus. Most of the larger aquatic annelids have gills to breathe. Otherwise they breathe through their moist skin, this is called cutaneous respiration
