Sea Lovers!

I know there hasn’t been much posting lately - the truth is, I’m back in the States and trying to make my Bermuda research publication-ready. I’ll be back to a more regular posting schedule as soon as I turn this paper in on Friday.

Cheers!

Aeolianites Bermuda’s exposed land is composed primarily of wind-blown sand dunes that have since compacted into limestone. Intense glacial fluctuations during the Pleistocene caused high seas to flood the platform, creating an environment perfect for dune-building. There are outcrops all around the island that show beautiful examples of the depositional layers!

Porous Sea Rod (Pseudoplexaura porosa) These soft corals undergo mass spawning events about 5-6 days after each of the summer’s full moons. Both sexes (yes, they have a gender) eject gametes for about 30 minutes, allowing them to combine in the water column. Some studies have shown that their ability to reproduce is based on size, as only colonies larger than 50cm have been observed to participate in this synchronized lunar activity.

Giant Caribbean Sea Anemone (Condylactis gigantea) As cnidarians, giant Caribbean sea anemones have stinging cells called nematocysts. The tip of each tentacle contains a neurotoxin that can injure (or even destroy) the nerve tissues of an attacker - however, the concentration is too low to harm a human. The stinging method is also used to catch prey by stunning small animals as the arms pull them in toward the anemone’s mouth.

Cathedral Reef (Bermuda) A popular dive site for tourists, this reef is named for the huge underwater dome you can swim down into at around 45 feet. It consists of a series of breaker reefs that have created a group of connecting caves, overhangs, and canyons. They’re relatively easy to swim through - but disorienting if you’re not used to cave diving. The top of the Cathedral has several holes where shafts of light penetrate the darkness of the cave in beams of holiness.

Lionfish love to gorge themselves. Their bellies can expand up to 30x the original size, so there’s not much to stop a voracious appetite from devouring everything in its path. The fish has become an invasive species in the Atlantic, forcing Bermuda to adopt a spear-on-site policy to try and control the population. This cute little guy managed to survive his spearing and now lives domestically in our lab aquarium. (His name is Larry.)
