Goby
Bloodlip Goby, Mud Goby
Goby is one of the most numerous fish families, with more than 2.000 species. They grow 1-30 cm and have an important role in cleaning
the bottom from various residues.
The combination of abdominal grown together fins and a dished body has similar characteristics as octopus' suction cups that serve goby
to the glue to the substrate, creating a negative pressure, which can support its weight in a vertical position.
Gobies are mostly residents of the coastal shallow sea, and are also numerous in brackish waters.
They mainly feed on small invertebrates and some larger species feed on smaller fish.
Sometimes they live in symbiosis with other marine organisms. One such example is the coexistence with prawns, where goby lives in a
hole made by a prawn and in return he does the scouting.
Glavoč
Glavoč krvoust, Glavoč blatar
Jedna od najbrojnijih ribljih porodica, s više od 2000 vrsta. Narastu od 1 do 30 cm. Imaju važnu ulogu u čišćenju dna od raznih ostataka.
Spoj trbušnih peraja koje su srasle zajedno i tvore tanjurasti organ ima slične osobine kao lovke hobotnice koji služi da se glavoč priljepi
za podlogu, stvarajući podtlak, koji može izdržati njegovu težinu i u okomitom položaju.
Glavoči su većinom stanovnici priobalnog dijela mora, malih dubina, a također su brojni i u bočatim vodama.
Uglavnom se hrane malim beskralježnjacima, a pojedine veće vrste se hrane manjim ribama.
ponekad žive u simbiozi s drugim morskim organizmima. Jedan od takvih primjera je suživot s kozicom, gdje glavoč živi u rupi koju je
napravila kozica, a on za nju "izviđa".
