Coastal Area Sacarma Bay Two Square Miles 8 Visits Snorkeling, Net, Camera, Boat, Land Approximately 15 points of observation Snorkeling The Habitat
Abiotic The non-living physical features of the environment. Biotic Living or once-living organisms in the environment. Abiotic & Biotic
Plants Groundcover Water Herbaceous Woody
Green Buttonwood Sea Grape Woody • Conocarpus erectus • 3-8 m tall • 2.5 cm to 9 cm long leaves • 1-3 cm wide leaves • Coccoloba uvifera • Grows up to 40 ft. • Fruit hangs down in clusters • Shiny, leathery leaves
Groundcover • Water Sprite (Ceratopteris thalictroides) • Skinny leaves • All Green • Found around water
Water Plants Turtle Grass (Thalassia testudinum) • Found in up to 100’ of water • Average growth is 2-4 mm per day • Will grow in temperatures of 20 to 40 degrees C
Water Plants • Neptune’s Shaving Brush • (Penicillus capitatos) • 3 inches tall • Underwater plant • All green color
Water Plants • Sea Fan (Gorgonia ventalina) • Flexible • Flat • Spread out to as much as 5’ & as tall as 6’
Water Plants • Sargassum Weed (Sargassum hystrix) • a.k.a. Gulfweed • Asexual reproduction • Type of brown algae
Animals Invertebrate • Animals without backbones are invertebrates. Sea Cucumber
Invertebrates • Hermit Crab • (Pagurus bernhardus) • Large claw is always on right side • Eats scraps and worms • Shells from 1” to 5”
Invertebrates • Horseshoe Crab • (Limulus polyphemus) • Considered “living fossil” • Spines all over • Light brown color
Vertebrates • Animals with a backbone are called Vertebrates. Great White Heron

Water pH • The pH of a substance is based on the basic or acidic level. • The pH scale ranges from 0 – 14. 7 is neutral, any anything below is acidic, anything above is basic. • The higher the number the more basic the substance is, the lower the number the more acidic. • The habitat’s pH remained constant at 8.4
Unique Site Factors • Diversity of plants and animals • Hardly any pollution in the air or water (pollution exists on land) • Various organisms in the site (not apparent at first glance) • Accessible by water or land • The Upside Down Jelly Fish (Cassiopea medusa) is most abundant organism
Ecologically Sensitive/Endangered Organisms • No Sensitive or endangered organisms were noted at the habitat site.
Human Impact • Trash – Negative Impact • It can kill animals; i.e. plastic can be swallowed or entangle species • Motor props - Negative Impact • Kill organisms on sea floor • Mangroves – Positive Impact • Under protection by law • Diving/snorkeling – Negative & Positive Impact • May interfere with the sensitive species due to touching, gathering specimen, etc. • Humans increase their knowledge and awareness of sensitive environment • Fishing – Negative Impact • May over fish and deplete species, interfering with food web cycle
Human Impact • At Habitat Site: I found lots of dead fish. These provided food for other animals, making it a positive impact for them, but too many were killed for no apparent reason and would lay there and rot. This is a negative impact.
