Tuna

Tuna entu seomplokan ikan laot nyang secara èlmu hayat masup suku Thunnini, deri kuarga Scombridae (makerel). Dia punya macem ada 15 spésiès (dalem 5 genera)^[1] nyang béda-béda ukuran gedénya, mulain deri nyang kecit nama tuna pèlor (5 cm; 1,8 kg) ampé nyang gedé banget nama tuna kèpèt biru Atlantik (4,6 m; 684 kg). Bolé dibilang, nyang rata-rata dia punya panjang entu 2 mèteran, èn dia punya idup entu dipercaya bisa ampé 50 taonan.

Biar tau ajè kalo tuna, opah, èn cucut makerel entu atu-atunya omplokan spésiès ikan nyang bisa ngejaga dia punye panas badan lebi tinggi daripada suhu aèr sekitarannya. Entakanuh, lantaran enni ikan pemangsa nyang gesit pisan, dia punya bentuk badan mulus panjang nyang bikin dia jadi sala atu tukang berenang paling cepet. Misalnya tuna kèpèt kuning, dia bisa ngebut ampé 75 km/jem.^[2]^[3] Laporan ilmiah lama ada nyang nyebutin kecepetan nyang lebi tinggi lagi, mar entu mah kaga' bener, cuman masing ajè sering nongol di makalah kesohor.^[3]

Gampang ditemuin di daèrah laot anget, enni ikan mah èmang uda deri jaman baholanya banyak ditangkepin secara komersil, ama bekèn juga' dipaké bakal sasaran lomba mancing di tenga laot. Walhasil, gara-gara kebablasan ditangkep orang, beberapa spésiès kaya' tuna kèpèt biru kidul, uda mulain terancem punah dah jadinya.^[4]
