The collection of algae, seagrasses and fresh water plants of TelAvivUniversity is the largest of its kind in the Levant. This collection contains over 30,000 tagged specimens. The vast majority of this collection consists of algae collected along the coasts of Israel and Sinai. The collection is at the beginning of a computerized cataloging process that relies on an existing catalog. At the end of this process, data will be available for academic studies by algal taxonomists of universities from around the world.

This collection is divided, by the type of preservation, into two collections. One collection contains moist specimens that were initially kept in formalin and recently transferred to alcohol. The second is a dry collection containing algae and other aquatic plants dried and attached to sheets.

Most specimens were found and collected by Dr. Yaacov Lipkin, who founded the collection in the Sixties of the twentieth century. At first, the collection was kept at Abu Kabir, former home of the Faculty of Life Sciences. This collection resides TelAvivUniversity at Ramat Aviv today. Since the beginning of the millennium the collection of algae and seagrasses started to grow again with the addition of thousands of new specimens. These samples clearly and unequivocally indicate changes in the composition of algal species in the Mediterranean shore of Israel. These changes are the result of invasion of alien seaweed species originating in the Indian and PacificOceans and the Red Sea. These species find suitable conditions for settlement due to the global warming of seawater that optimize the environment for the invasion of tropical species.

The Algal collection contains specimens of four groups: Cyanobacteria, Chlorophyta, Rhodophyta and Ochrophyta. This collection is growing steadily in recent years with the addition of new species to Israel, the Mediterranean Sea and even new species to science. Seagrasses collection contains many specimens collected in the Red Sea. The collection of freshwater plants contains specimens of Phylum Charophyta and samples of very rare water mosses. The algal and seagrasses collections are currently in use for phytogeography study of the floristic changes that took place along the Israeli shore.
