Ele­phant Nose Fish – Gnathone­mus peter­sii. A species of the Mormyri­dae fam­i­ly that has 18 genus and 200 species!

Gnathone­mus peter­sii appear thin and oblong. Col­ors range from dark brown or gray fea­tur­ing white markings.

Nose shapes resem­ble the trunk of an ele­phant, hence their name.

A weak elec­tri­cal organ, locat­ed at the nar­row part of body where the tail attach­es, is used for sens­ing. This enables the ele­phant nose fish to com­mu­ni­cate with oth­er fish, detect preda­tors and foods.

It can feel the slight­est move­ments as the field around it is dis­turbed. Because the ele­phant nose fish – gnathone­mus peter­sii is noc­tur­nal, it can move through shad­ed or murky water, even at night.
