EGGS AND LARVAE |
The larva of a
polychaete worm
|
 |
| The tadpole larva
of a tunicate. This free swimming larva shows the
relation with chordates. In later life it will
attach itself to a substrate and transform into
the adult sack-like form. |

 The egg capsule of the mollusc Littorina
|
| The waters of the
Oosterschelde in the Netherlands are rich in many
species of marine organisms. In the months March
and May the bloom of algae (especially diatoms)
has it's effect on the reproduction of many
animals. Many of the larvae feed on the algae.
During the meeting of Dutch and British
microscopists in May '98 we saw larva of many
species. This page portrays some of these. More about the meeting can be read in
the Micscape article Renesse and on the Quekett Club site

|
| This picture of a
gastrula shows the way many organisms begin their
larval development. This one could become a
starfish. The beginning of a gut is already
visible. |
