Albino Mollusks vs Normal Mollusks
有白化現象和正常的軟體動物貝殼
The total lack of pigmentation in a living animal can be the result of genetic variability or mutation. Without the normal coloration of the living animal, and in this case including its shell, albino animals seldom escape the eyes of predators to reach adulthood.
活著的軟體動物貝殼完全缺乏色素可能是遺傳變異或突變的結果。沒有正常顏色的軟體動物貝殼，在這種情況下，包括它的外殼，白化軟體動物貝殼很少能逃脫捕食者的眼睛，達到成年。
These particular mollusks managed to reach maturity and pass along their genetically inherited traits to future generations. Each pair exhibits the normal coloration along with the extremely rare albino of each species.
這些特殊的軟體動物設法達到成熟，並將其遺傳的特徵傳給後代。每對都表現出正常的著色，以及每個物種極其罕見的白化病現象。
#zhihu知乎 provides the following explanation of the word “albino”:
Albino /ælˈbainǝu/ 是一個形容詞，用來描述那些由於遺傳原因而缺乏黑色素的生物。這種缺乏黑色素的生物通常呈現出白色或淡黃色的外觀，眼睛可能會是紅色或粉紅色，因為血管的顏色透過缺乏色素的視網膜顯現出來。在生物學上，這種狀態被稱為白化病或白化症。
在動物界，白化現象常見於各種物種，包括蛇類。例如，緬甸蟒（Burmese Python）中就有白化個體，這種個體被稱為白化緬甸蟒或黃金蟒。它們的皮膚和鱗片呈現出獨特的金色或奶油色，非常罕見且具有很高的觀賞價值。白化緬甸蟒是由於特定的遺傳基因突變導致黑色素的生成受到抑制，從而產生了這種特殊的顏色。
在服裝面料領域，Albino 並不是一個常見的品牌名稱。然而，有提到的 Albini 是一個著名的意大利面料品牌，以其高品質的襯衫面料聞名。雖然 Albini 不是直接與 Albino 有關，但它的名字可能在某些情況下被誤讀為 Albino，尤其是在討論高端襯衫面料時。
總之，Albino 主要指的是白化現象，這是一種生物學上的特性，而不是一個特定的品牌或種類。在不同語境中，它可能被用來描述具有白化特徵的生物或物體。

白化軟體動物 vs. 普通軟體動物
白化軟體動物與普通軟體動物的主要區別在於色素沉澱，這是由影響黑色素或其他色素生成的基因突變所導致的。以下是詳細比較：
1. 色素與外觀
- 白化軟體動物：缺乏黑色素或其他色素，導致外觀呈現蒼白、白色或半透明。有些可能仍會顯示出微弱的顏色，取決於未受白化影響的其他色素。
- 普通軟體動物：具有各種顏色與花紋，通常用於偽裝、吸引配偶或發出警示信號。
2. 貝殼與軟組織差異
- 白化軟體動物：貝殼可能呈現白色或淡色，尤其當色素基因影響貝殼形成時。其軟體（如身體、觸手）通常為半透明或淡色。
- 普通軟體動物：貝殼與軟組織具有多種顏色與花紋，適應環境需求。
3. 視覺與感官適應
- 白化軟體動物：若擁有眼睛，可能因視網膜缺乏色素而導致視力受損，類似於其他動物的白化症狀。
- 普通軟體動物：視覺功能正常，並適應其生存環境。
4. 生存與掠食風險
- 白化軟體動物：由於缺乏偽裝能力，更容易被捕食者發現。此外，若生活在淺水區，可能對紫外線較為敏感。
- 普通軟體動物：自然色素有助於偽裝與防禦，提高生存機率。
5. 稀有性與遺傳基礎
- 白化軟體動物：由罕見的隱性基因突變導致色素生產受阻。白化現象可見於蝸牛、蛤蠣、章魚等軟體動物物種中。
- 普通軟體動物：擁有顯性色素基因，使其展現多種正常顏色與花紋。
6. 環境與演化影響
- 白化軟體動物：在野外生存較為困難，但在人工飼養環境（如水族館）可能更易存活，甚至成為珍稀觀賞物種。
- 普通軟體動物：能夠適應不同生態環境，顏色與花紋有助於提升其生存與繁衍機率。
白化軟體動物雖然稀有且獨特，但通常更容易受到環境壓力的影響。然而，在受控環境下，牠們可能因特殊外觀而受到重視。
Albino mollusks differ from normal mollusks primarily in pigmentation due to genetic mutations affecting melanin or other pigment production. Here’s a detailed comparison:
1. Pigmentation and Appearance
- Albino Mollusks: Lack melanin or other pigments, resulting in a pale, white, or translucent appearance. Some may still exhibit slight coloration depending on other pigments not affected by albinism.
- Normal Mollusks: Have various colors and patterns, often used for camouflage, mate attraction, or warning signals.
2. Shell and Soft Tissue Differences
- Albino Mollusks: Their shells may appear white or faintly colored if pigmentation genes affect the shell as well. Their soft tissues (e.g., body, tentacles) are often translucent or pale.
- Normal Mollusks: Display a wide range of colors and patterns due to environmental adaptation and genetic diversity.
3. Vision and Sensory Adaptations
- Albino Mollusks: If they have eyes, they may suffer from vision impairments due to lack of pigment in the retina, similar to albinism in other animals.
- Normal Mollusks: Have normal eye function, adapted to their environment.
4. Survival and Predation
- Albino Mollusks: More vulnerable to predators due to lack of camouflage. They might also be more sensitive to UV radiation if exposed to sunlight.
- Normal Mollusks: Benefit from natural pigmentation that helps in camouflage and defense.
5. Rarity and Genetic Basis
- Albino Mollusks: Occur due to rare recessive genetic mutations that disrupt pigment production. Albinism in mollusks is observed in species like snails, clams, and octopuses.
- Normal Mollusks: Have dominant pigmentation genes, leading to typical coloration patterns.
6. Environmental and Evolutionary Impact
- Albino Mollusks: May have a harder time surviving in the wild but could thrive in controlled environments like aquariums.
- Normal Mollusks: Well-adapted to their ecological niches with colors suited for survival.
While albinism in mollusks is fascinating, it often makes them more susceptible to environmental pressures. However, in captivity, albino mollusks can be prized for their unique appearance.
