The most common pattern of the lateral line system on the caudal fin of Gobiidae is characterized by three longitudinal rows of free neuromasts. Deltentosteus collonianus and Deltentosteus quadrimaculatus are two benthic Atlantic–Mediterranean gobiid

Length distribution, sex ratio, length-weight relationship, age, growth, spawning period, age, and length at first maturity of four-spotted goby inhabiting Izmir Bay were investigated. A total of 1696 four-spotted goby were collected by trawl hauls between

Age estimations were made using otolith length and weight measurements from 3 goby species in the central Aegean Sea: the four-spotted goby (Deltentosteus quadrimaculatus Valenciennes, 1837), the black goby (Gobius niger Linnaeus, 1758), and Fries's goby
