The lumpsucker is a fish species, found in the Baltic Sea near Lithuania, also known as the sea-toad. Lumpsuckers are named appropriately enough: they are short and round, have no scales and are covered with warts like real toads.
Lumpsuckers are interesting bottom-dwelling fish of unusual form found in the Baltic Sea. They live on a rocky bottom where they use to adhere with their pelvic discs to rocks. During the spawning season the male becomes reddish in colour, whereas the female is blue-green. Lumpsuckers grow up to 5 kg in weight. The broods of big and red roe are guarded by males for about two months. Males take care of hatchlings which in the event of danger use to cling with adhesive pelvic discs to their "father".
Lumpsuckers and other species of fish inhabiting the Baltic Sea and rivers and/or lakes of Lithuania will be exposed in the reconstructed Aquarium. Here the visitors will be pleasantly surprised by a transparent tunnel arranged under the central pool with sturgeons. The acrylic tunnel of 20 m long will allow them feel like walking under the water.
