Pomatoschistus minutus

Species biology: The sand goby inhabits shores of the NE Atlantic and the Baltic Sea. Its behaviours and reproductive strategies include exclusive paternal care with males building nests under mussel shells. The sand goby is euryhaline i.e. it is able to adapt to a wide range of salinities, however, not to fresh water. Sand goby life stages from pelagic fry to adults are staple food for cod and other large commercial fishes.

Rationale for genome sequencing: The sand goby is a small and experimentally tractable fish, which is exceptionally well-studied when it comes to reproductive biology and behavioural ecology. It is also used e.g. in studies of adaptive genetic evolution in different seawater environments. Phylogenetically it has an interesting position with respect to teleost evolution and the family of gobies has a worldwide distribution with 2000 species of gobies making generalizations and comparative studies possible.
