Changu

Changu au tangu ni samaki wa baharini wa familia Lethrinidae ya oda Spariformes katika ngeli Actinopterygii walio rangi ya majivu au fedha pamoja na madoa, milia au sehemu za mwili zenye rangi angavu. Wanatokea katika maji ya kitropiki ya Bahari za Hindi na Pasifiki huku "Lethrinus atlanticus" akiishi katika Bahari ya Atlantiki pia. Mara nyingi hupatikana kwenye miamba ya matumbawe ambapo hula invertebrata na samaki wadogo. Wengine wana meno yafananayo na magego yanayowasaidia kula invertebrata wagumu kama moluska na kaa.

Familia hii ina spishi 45 duniani kote. Spishi 20 zimeriportiwa kutoka Afrika ya Mashariki.

Kuna spishi za familia Lutjanidae na Nemipteridae zinazoitwa changu pia, lakini majina janja na chenda yanapendelewa kwa mtiririko huo.
