Watermakers for boats turn seawater fresh. Freshwater is heavy. At 8.35 pounds per gallon, you don't want to carry a lot of water while cruising. Once you anchor, the generator is turned on and your onboard watermaker starts making freshwater. The power of having watermakers for boats can be summed up into one word: convenience. How Watermakers for Boats Work: The Science of Seawater Conversion Watermakers use pumps, filters, and membranes to purify raw seawater into freshwater. The process, reverse osmosis, is the same desalination plants use on a large scale. At the heart of the process is the membrane, a filter with pores the size of a red blood cell. After the larger particles in seawater are filtered out, the high-pressure pump forces water through the membrane removing almost all the dissolved solids. This method rejects up to 99 percent of salts, contaminates, and pollutants from seawater.   Heat and standing seawater create the ideal environment for biological gr...

在水族箱现有的那些外表绚丽，能给人以视觉享受的鱼类中，金毛巾可谓独树一帜。绚丽的色彩、醒目的条纹使它们成为养鱼爱好者眼中的"香饽饽"。它们天性娇弱，胃口独特，捕食行为也异于其它鱼类，这些特性常常让岩礁爱好者不知所措。也许没有哪条神仙鱼能像金毛巾（毛巾鱼）一样诠释这一点了。但是绚丽的金毛巾却难以适应人工环境，而且不能与水族箱里的珊瑚共处。但对于养鱼的老手而言，金毛巾可谓是水族箱中最耀眼的存在，它值得您的呵护与关怀。 金毛巾的与众不同之处并不仅仅在于绚丽的外表。它可是神仙鱼盖刺鱼科甲尻鱼属的独苗。金毛巾的分布范围十分广阔，遍及印度洋西北部、红海以及印度 - 太平洋。此鱼通常栖息于珊瑚密集区，海水深度为 3-150 英尺之间。金毛巾通常独自出没，偶见成对出游，成群出动则较为罕见。在自然环境下，金毛巾的性情较为孤僻，害羞，喜欢 呆在洞穴，裂缝旁边。平时以 底栖无脊椎动物 为食，尤其喜食海绵及 被囊类动物。金毛巾并非侏儒型神仙鱼，它属于小型神仙鱼，最大可长至23厘米 。 金毛巾拥有蓝白及黄橙相间的竖条纹。后部 背鳍 为蓝色，尾鳍黄橙相间，臀鳍同为黄橙相间或为蓝色条纹。此鱼着实十分美丽！不像其它神仙鱼，雄性雌性金毛巾在色彩上没有差异（科学家通常认为金毛巾不具有二色变异的特征）。然而金毛巾幼鱼与成鱼的 区别却很明显，原因在于成鱼的条纹更为厚实，背鳍的眼状色斑也更为圆润。捕自印度洋及红海一带的金毛巾在胸部与头部区域有黄橙相间的条纹，栖息在太平洋的金毛巾通常在胸间与头部区域有蓝灰相间的条纹。在褪去了幼年眼状色斑的成鱼标本中，上述来自不同海域的金毛巾在胸部颜色上的差异则更为明显。 印度-南太平洋变种金毛巾 印度洋与红海变种金毛巾 海洋水族馆网站时常提到太平洋（蓝腹）与红海（黄腹）金毛巾的细微差异。我们通常听闻红海毛巾的体格更为强壮，同时也更受人们的欢迎。然而太平洋毛巾可是个难伺候的主，它们更难适应新的环境。上述情形与鱼本身并没有太多的联系，关键在于人们捕获、处理以及装运毛巾时所采取的手段。无论是哪种金毛巾，养鱼爱好者必须在挑选及照料脆弱的金毛巾时投入更多的精力。老手们之所以能取得成功，是因为他们通常会花大把时间了解金毛巾的习性并学习他人的经验，目前已有很多关于金毛巾在岩礁箱中茁壮成长的成功案例。 如何挑选金毛...

Richard Cunningham Harrel lived the majority of his life in nature, be it through his hobbies, work or time spent with family. The former Lamar University biology professor died in his favorite rocking chair Oct. 8, but his love of nature and knowledge of the environment lives on within his family and former colleagues and students. In addition to his work at Lamar and a local environmental advocacy group, Richard also had a love for fishing and simply being outside, according to his daughter Terri Harrel. Granddaughter Lauren Hardman said that love of nature has now been passed down through generations of family.

Before you bring home your pet turtle, you need to start with a few basic items. For a young turtle, the best size tank is at least 20 gallons, but it will need to be upgraded before adulthood. On average, adult turtles need a minimum of a 40-gallon tank to give them room to grow and move. Along with a heat lamp and UV light, adding rocks and stones gives them basking areas. You also need a high-quality filter for the aquarium's water supply, though it is not a replacement for a consistent cleaning routine.

Vividly colored cichlid parrot fish make a big splash in a tropical aquarium, but with their popularity riding high, what can you safely place them with? Let's discover the 12 best tank mates to pair with parrot fish to create a harmonious and attractive underwater kingdom. Parrot Fish: Species Overview Cichlid parrot fish are popular tropical freshwater fish hybrids. Their chunky bodies, friendly expressions, and vivid colors brighten an aquarium. With the right care, they can live 10 to 15 years and reach 10 inches long. Don't confuse them with coral reef-eating wild parrotfish, which are a completely different species. These cheerful cichlid fish don't exist in the wild, and no one is sure exactly what their parentage is! Some experts suggest they're a cross between Central and South American cichlids. In terms of history, we know they appeared from Far East fish farms around 35 years ago. Today, cichlid parrot fish often replace traditional goldfish in tropical tank...

Witnesses to Wednesday's fatal vehicle explosion on the U.S.-Canada border described the incident that reportedly killed a husband and wife on their way to a KISS concert as "a ball of fire" noting it they had "never seen anything like it" before. Law enforcement analyst John Miller told CNN's  The Situation Room  the 56-year-old driver of the vehicle lived on a "very upscale island" in New York and may have suffered a "medical emergency." Authorities did not identify the names of the couple. The pair were on the way to a KISS concert, which was later canceled by frontman Paul Stanley due to illness, according to the DailyMail. Several witnesses recalled the moments leading up to the fatal crash noting that the $300,000 white Bentley was speeding toward Rainbow Bridge at "over 100 miles an hour," before "flying" in the air. "We were walking up the road and we [saw] this car coming down t...

Leishmaniasis is a skin-affecting, tropical disease that may now be endemic to the United States. Leishmaniasis is a disease caused by the protozoan parasite Leishmania —historically found in the tropics, subtropics, and parts of southern Europe. Transmission occurs when a female sandfly infected by the parasite then bites a human. [ ]   Leishmaniasis takes different forms: Cutaneous Leishmaniasis (CL), mucocutaneous Leishmaniasis (MCL), and visceral Leishmaniasis (VL). [ ] There are several different Leishmania species, including: L. (L.) major, L. infantum, and L. (L.) tropica (found in the Mediterranean, the Middle East, Africa, and India) L. (L.) amazonensis , L. (L.) chagasi , L. mexicana L , L. (Viannia.) naiffi , L. (V.) braziliensis , and L. (V.) guyanensis (found in the Americas) The 'old world' strains "predominantly cause self-limiting ulcers, whereas New World species can be severely destructive and even cause death, mostly in relation to MCL disease...
