海帶目是褐藻綱之下一個目級的海藻分類單元,現時包括有約30個屬[來源請求]。 這些海帶生長於淺海海洋底下的海藻林:一種類似於陸地上森林的海洋植物群落,估計從中新世(即500到2300萬年前)就已出現[3][與來源不符]。
分類
本目包括下列各科[4]:
- 厚岸藻科(Akkesiphycaceae)
- 翅藻科(Alariaceae)
- 繩藻科(Chordaceae)
- 多肋藻科(Costariaceae)
- 海帶科(海帶科)
- 巨藻科(Lessoniaceae)
- 擬繩藻科(Pseudochordaceae)
生長和繁殖
生長在分生組織基部發生。
海藻林
海帶目聚集的地方會發展成被稱為「海藻林」的海底森林,為最富有豐富生產力與多樣性的地球生態系統[5][6]。較小片的海藻林又被稱為海藻床。在挪威海岸,有接近5800平方千米的海岸就長滿了海藻林[7][6],還為大量動物提及棲息地[8][9]。
海藻林分佈於溫帶到極地地區的沿岸海域。[5]在2007年,於厄瓜多爾附近的熱帶海域也發現有海藻林分佈。[10] 和熱帶的珊瑚礁一樣,海藻林為許多生物提供生活環境,包括軟體動物、甲殼動物、棘皮動物、魚類及海洋哺乳動物等;同時也為人類提供生產力豐富的漁場。
商業用途
巨型海帶由於其表面的樹冠和在較深水域停留的生長習性,可以相當容易地收穫。
