A Hopeful New Year for the Florida Manatee

January 21st, 2019tinalc0 Comments

A few weeks ago, I had the honor of sharing space with a manatee while cave diving. No, it wasn’t in the cave. The manatee was enjoying the constant 72 F spring water to warm up during the chilly day. I, on the other hand, was using the run to get to and from the Devil’s Cave system at Ginnie Springs. This isn’t the first time I have had the opportunity to observe these magnificent creatures in their underwater world. Earlier in 2018, I snorkeled with manatees in the Crystal River. Yet another perk of living in Florida. Regardless, their …

The Manatees Return

As winter descends on the Northern hemisphere, the costal waters surrounding Florida begin to cool. Warm waters that see temperatures in the low 80s for most of the year drop to the mid 60s and below. For the West Indian manatee, or manatee for short, sustained water temperatures of 65° F and below can be incompatible with life. Luckily for these underwater mega-herbivores Florida is home to several freshwater springs that maintain a constant temperature of 70-72°F year-round. Estuaries and rivers leading from the Gulf of Mexico and Atlantic Ocean give easy passage to these winter havens. …

Sea Otters: A Species Under Threat

September 29th, 2012tinalc0 Comments

With the new challenges wildlife faces daily, it is no longer enough just to survive. To ensure species longevity, individuals must learn to quickly adapt. Although a lot of attention is given to the conservation of the large, iconic creatures of land and sea, it is often those species that reside in the middle of the food chain that play the most vital rolls in ecosystem balance that are overlooked. One particular animal that fits into this category is the sea otter. Like all otters, the sea otter is a member of the weasel family. The three subspecies of Enhydra …

The Ocean: Where Life Begins and Ends

September 25th, 2011tinalc0 Comments

The ocean, for most, represents a great blue void. It is sometimes hard to imagine that an incredible world, much larger than the space terrestrial beings inhabit, lies beyond the shoreline and below the surface. The Censes of Marine Life, completed in 2010 by 2,700 scientists from 80 countries, identified more than 1 million species that call the ocean home. In addition, researchers feel that despite their great accomplishment, 50-80% of the species inhabiting the sea surrounding South Africa, Antarctica, Japan, the Mediterranean, and Australia are yet to be discovered. The ocean covers 71% of Earth’s surface and holds 97% …
