This study reveals how different goldfish are from their wild counterparts, with an exceptional morphological diversity among breeds. Divergence and innovations are found in their overall external morphology, skull, hearing structures, and brain, sometimes accompanied by physiological impairments. As with pigeons and dogs, artificial selection for ornamental purposes in goldfish has favoured the acquisition of unique morphologies nonviable in natural environments. However, how goldfish diverge from their wild counterparts is unique, highlighting also a lack of universality in the domestication process.

"Using 21st century tools on a dataset comprising the 16 main goldfish breeds, 23 wild close relatives, and 39 cypriniform species, we show that Charles Darwin’s expressed wonder at the goldfish is justified."

"In goldfish as well, the intensity of breeding selection for ornamental purposes led to major morphological innovation. Some traits have never been recorded in wild specimens, such as the caudal bifurcation of the axial skeleton in twin-tail breeds. Goldfish do not include as many breeds as other domestic animals, but there is considerable morphological diversity in them. In contrast, there are hundreds of recognized breeds of dogs and pigeons. Concerning the time and mode of origin of such diversity, historical sources document how already the Song (960–1279) and Ming (1368–1598) Chinese dynasties record the major kinds of goldfish, including most of the breeds present in our sample from the 15th and 16th centuries."

𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁
Domestication process effects are manifold, affecting genotype and phenotype, and assumed to be universal in animals by part of the scientific community. While mammals and birds have been thoroughly investigated, from taming to intensive selective breeding, fish domestication remains comparatively unstudied. The most widely bred and traded ornamental fish species worldwide, the goldfish, underwent the effect of long-term artificial selection on differing skeletal and soft tissue modules through ornamental domestication. Here, we provide a global morphological analysis in this emblematic ornamental domesticated fish.

We demonstrate that goldfish exhibit unique morphological innovations in whole-body, cranial, and sensory (Weberian ossicles and brain) anatomy compared to their evolutionary clade, highlighting a remarkable morphological disparity within a single species comparable to that of a macroevolutionary radiation. In goldfish, as in the case of dogs and pigeons in their respective evolutionary contexts, the most ornamented varieties are extremes in the occupied morphological space, emphasizing the power of artificial selection for nonadaptive traits. Using 21st century tools on a dataset comprising the 16 main goldfish breeds, 23 wild close relatives, and 39 cypriniform species, we show that Charles Darwin’s expressed wonder at the goldfish is justified.

There is a commonality of overall pattern in the morphological differentiation of domesticated forms selected for ornamental purposes, but the singularity of goldfish occupation and extension within (phylo)morphospaces, speaks against a universality in the domestication process.

𝗣𝗵𝗼𝘁𝗼 𝗖𝗿𝗲𝗱𝗶𝘁
Fully dichotomous phylogeny used in PCoA. We crafted the phylogeny based on the genera in our sample present in the robust molecular phylogeny of Stout et al. (2016), conserving branch lengths. We added goldfish and some Cyprininae to the tree based on the phylogenies of Tang et al. (2011) and Podlesnykh et al. (2015), duplicating the branch lengths of Gymnocypris from the phylogeny of Tang et al. (2011). We forced the dichotomy of incorporated taxa by following the phylogeny of Chen et al. (2020) and the diagrammatic genealogy of Smartt (2008). The production of this tree in addition to the tree shown in Supplementary Figure S2 is justified by the need to incorporate a fully resolved tree for PCoA. As a control test, we provide additional analyses without the incorporation of phylogeny (Supplementary Figure S3). Fish illustrations are not scaled, and references are available in Supplementary Table S7.

【珊瑚居大不易！海景第一排的空間競爭】
身為人類的我們，不時會為了租房、買房等居住問題煩惱不已，選擇居住地點得考慮生活機能、環境舒適度等等。偷偷跟你說：有群生物們為了居住問題，總是時時刻刻激烈作戰，那就是住在海景第一排的珊瑚們！

#珊瑚的一級戰區必爭之地
也許你已經知道，淺海珊瑚生長在海岸線之下，與共生藻合作行光合作用。可想而知，大多珊瑚喜愛的居住地點包含了幾個條件：位於低潮帶以下、陽光可達的深度、溫暖舒適、海浪沖刷力道恰好，以及能讓珊瑚站穩附著的硬底質。

篩選條件後，大致就是位在熱帶至亞熱帶的淺海、水深0公尺到30公尺的硬底質海域。這裡可謂眾多淺海珊瑚的一級戰區、兵家必爭之地！珊瑚為了爭奪棲身之所，無不使出全身解數、猛烈競爭。如果你剛好覺得自家隔壁鄰居很難相處，就看看珊瑚是如何相互霸凌的吧！

#慢動作廝殺的惡鄰們
也許在多數人眼中，珊瑚只是某種靜態的美麗地景，但看似安寧美好的珊瑚海，實際上卻是一片戰場。珊瑚分出勝負的時間短則一天，長則三週。儘管我們難以察覺，對珊瑚而言，卻是隨時都正上演著慢動作的激烈互毆。

狡詐招數①：把鄰居消化掉再吃掉
當一些石珊瑚發現周遭鄰居太靠近，會伸出消化性的「隔膜絲」（mesenterial filaments），覆蓋弱勢的鄰居，將對方分解、吃掉。這招可以快速解決近鄰，昨日好端端的鄰居，今天可能就只剩光禿禿的骨架。珊瑚蟲的活動往往都在夜間進行，駭人案件發生得神不知鬼不覺。

狡詐招數②：用掃把觸手刺殺鄰居
面對距離相對遠的鄰居，優勢的珊瑚還有另一招！「掃把觸手」（sweeper tentacle）的長度約為普通觸手的十到二十倍。伸出掃把觸手，就好比拿著長槍橫掃四周、刺殺戰場上的敵人。這個方法比較花時間、也需要投入更多能量，但為了住得舒適安穩，這都不算什麼啦！

狡詐招數③：釋放毒素抑制鄰居
打不過人家？那就下毒吧！軟珊瑚不像石珊瑚具有隔膜絲，卻擁有防禦手段——釋放化學毒物，以此抑制石珊瑚靠近。空間競爭戰中處於劣勢的珊瑚們必須想辦法活出生天，因此有些策略是下毒，有些是多生一點，有些則是長快一點。

狡詐招數④：遮蔽鄰居的陽光
淺海珊瑚競爭黃金地段的關鍵之一，就是為了獲取白天的陽光，好讓體內的共生藻行光合作用。因此，只要長得夠快就能形成優勢，「一手遮天」讓鄰居曬不到太陽、難以生存！

珊瑚的交鋒時常會在聚落之間留下明顯的「地界」，其他時候則可能造成珊瑚的變形與孔洞，那是腥風血雨的證明。事實上，從珊瑚還只是一隻浮游幼蟲，就非常注重選址了！

#浮游珊瑚幼蟲選址大作戰
珊瑚的受精卵在水中漂浮幾天或幾週，便會發育為浮浪幼蟲。幼蟲具有趨化性（chemotaxis）和趨光性（phototaxis），能對環境中的化學物質與光線做出反應，以有限的行動能力決定自己要落腳在哪一個位置。比如說，當幼蟲感受到此處有許多同類的排泄物，就代表此處可能是宜居之所！

#住不下去只好按下彈射椅按鈕
居住環境越來越糟糕該怎麼辦？多數珊瑚只能原地衰弱死亡，而少數珊瑚種類像是列孔珊瑚和柱珊瑚，則有避難奇招——「珊瑚蟲跳脫」。這個救命機制就像戰機的彈射座椅，讓飛行員棄機求生。當單一珊瑚蟲脫離骨骼、離開群落，便能讓海浪帶走重新物色新家。對珊瑚蟲來說，逃避並不可恥～珊瑚蟲跳脫能讓生命另闢蹊徑！

珊瑚除了透過釋出精卵來達成有性生殖之外，也有出芽、分裂、斷裂、珊瑚蟲跳脫等無性生殖的手段。每逢風浪將珊瑚的分枝打斷、沖走，只要環境適合，斷裂的小分枝依然可以重新長成珊瑚群體，這也是為什麼在珊瑚的人工復育中，常使用斷裂生殖的方法。

讀到這裡，珊瑚對居住空間的認真態度是否感動了你？下次拜訪珊瑚海時可別小看這群看似寧靜的生物喔！
