Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

ciliated sponge

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

ciliated sponge

Sycon ciliatum, the ciliated sponge, is a small calcareous sponge in the family Sycettidae, widely distributed along the coasts of Europe and the North Atlantic. It grows as a slender, vase-shaped or cylindrical solitary body, typically 1–5 centimeters tall, with a distinctive fringe of long spicules surrounding the apical opening (osculum), which gives it its ciliated appearance. The sponge is white to pale yellow and is found attached to rocky substrates, algae, seagrass, shells, and pier pilings in shallow subtidal and lower intertidal zones. Sycon ciliatum is a filter feeder, drawing water through its porous body wall and extracting bacteria, phytoplankton, and organic particles. It is one of the most studied calcareous sponges and has been used extensively in developmental biology research due to its relatively simple body plan. The species is not assessed by the IUCN. Calcareous sponges in the class Calcarea, including Sycon, have been important in understanding the evolution of sponge body plans. Sycon ciliatum reproduces both sexually, releasing larvae that settle on available substrates, and asexually by budding. It is common and not considered threatened across its European coastal range. The species provides microhabitat for small invertebrates and forms part of the diverse encrusting community of rocky subtidal habitats.
