Swartstert-dikkop ( Afrikaans )

provided by wikipedia AF

Die Swartstert-dikkop (Ptereleotris heteroptera) is 'n vis wat voorkom in die Stille Oseaan, die Indiese Oseaan, die Rooisee en aan die ooskus van Afrika tot by die noorde van KwaZulu-Natal. In Engels staan die vis bekend as die Spot-tail dartfish.

Identifikasie

Die vis word tot 12 cm lank en is lank en skraal. Die lyf is lig blou-grys met 'n swart kol op die geel stertvin. Daar is 'n iriserende blou ring om die oë‎.

Hulle leef in tropiese strandmere en koraalriwwe in water wat 7 tot 46m diep is. Die vis is gewoonlik alleenlopers maar leef ook in pare of groepe saam. Hulle verkies sand en klipperige bodems waar hulle gewoonlik net bo die bodem rond beweeg naby hulle skuiling. Die visse vreet soöplankton. Die visse is sku en gaan vinnig veiligheid soek in hul skuiling sodra hulle genader word.

Täplänuolikko ( Finnish )

provided by wikipedia FI

Täplänuolikko (Ptereleotris heteroptera) on nuolikoihin kuuluva kala.

Koko ja ulkonäkö

Täplänuolikko kasvaa noin 12 cm pitkäksi. Sen vartalo on vaaleansininen, evät tummemmat. Pyrstössä on kalalle nimen antanut musta täplä.[2]

Alkuperä

Täplänuolikko elää luonnossa Indopasifisella merialueella.[3]

Käyttäytyminen

Täplänuolikkoja tavataan luonnossa usein pareittain. Akvaariossa se on niin aggressiivinen lajitovereita tai muita suunnilleen saman muotoisia kaloja kohtaan, että sitä pidetään joko yksin tai parina mutta ei useampien nuolikkojen kanssa.

Ravinto

Täplänuolikko syö eläinplanktonpitoista ruokaa sekä vedestä että pohjalta. Sitä on syötettävä kolme kertaa päivässä, ellei altaassa kasva tarpeeksi planktonia, jota se voi saalistaa itsekseen.

Ptereleotris heteroptera ( Italian )

provided by wikipedia IT

Ptereleotris heteroptera (Bleeker, 1855) è un pesce di acqua salata appartenente alla famiglia Microdesmidae ed alla sottofamiglia Ptereleotrinae.

Distribuzione e habitat

È una specie Indo-Pacifica il cui areale ha limite nord alle Ryūkyū e sud all'isola di Lord Howe; è diffusa nel mar Rosso. Vive fino a 46 m di profondità, spesso in baie e lagune e sia su fondali sabbiosi che rocciosi[1].

Descrizione

Presenta un corpo allungato e compresso lateralmente che non supera i 14 cm[2]. La colorazione non è molto vistosa e varia dal grigio bluastro all'azzurro pallido. Come nelle altre specie del genere Ptereleotris, presenta scaglie cicloidi; la seconda pinna dorsale è più alta della prima. Le pinne sono trasparenti ad eccezione della pinna caudale, che è biloba, giallastra e con una macchia scura al centro.

Biologia

Comportamento

Gli adulti formano coppie, mentre i giovani possono formare grandi gruppi, anche di 500 esemplari[1].

Alimentazione

Si nutre di zooplancton[2].

Predatori

È spesso preda di carangidi come Carangoides fulvoguttatus[3] e di uccelli marini come la sterna stolida bruna, di cui è una significativa parte della dieta a French Frigate Shoals[1].

Conservazione

È una specie comune dall'areale molto esteso, quindi la lista rossa IUCN la classifica come "a rischio minimo" (LC)[1].
