Growing up I remember being entertained on my outings to the beach by Bull Kelp. Dragging the long whips along the beach and puncturing the bulbs to hear the sound of the gas escaping. Until recently I have never thought of the … Continue reading Bull Kelp
Naturally, I have to talk about something from the state up North. Although there are Orcas–northern residents and transients–in Alaska, I am much more familiar with the humpbacks. Humpbacks, Megaptera novaeangliae, are pretty much the cutest thing on earth… if … Continue reading Orcas make me smile, but Humpbacks make me splooge!
Until a week ago, I could not have told you the difference between a porpoise and a dolphin, and in fact, would have used the terms interchangeably. No longer, my friends! I have been learninated! At the Whale Museum last … Continue reading Porpoise or Dolphin?
Undoubtedly the darlings of Pacific Northwest megafauna, whales have captured our imagination for centuries. Vicious killers, gentle grazers, awe-inspiring and reverent, whales have filled human culture with imagery and lore that persists to this day. But are whales truly the … Continue reading Holy Sea Cow!
Whale lice. Who’da thunk it? At the Whale Museum last Thursday, most of you probably noticed the display case containing various parasitic invertebrates that can sometimes cause whales a lot of grief. One of the species displayed was the parasitic whale barnacle Coronula diadema. These barnacle infections occur frequently and are endemic to many ceteacean’s lifestyle (i.e., humpback and greys for example). Even though they are important, let’s face it they’re not as interesting as freakin’ WHALE LICE!! What a crazy concept. I mean you see barnacles in the intertidal zone all the time. So for this entry I’ll focus … Continue reading Cyamida: The other other other cetacean health concern
Cetaceans break my heart. They are the fragile and failing embodiment of old earth intelligence and majesty. Ever floating, flying, falling within a deep blue salty matrix of emotional complexity: empathy, loyalty, compassion, delight, elation. Further reinforcing this mystique and sensitivity last week was the Whale Museum’s revelation of the cultural breadth and character of Orca matriline song clans and formal pod greeting ceremonies. It makes me sad. Truly. To think how singular and momentous they are and how close they have come to vanishing completely. So… in an effort to fend off the potential for waxing melencholic… I’m posting a blog on blowing bubbles! Humpback Whale Bubble Blowing Humpback whales are efficient and practical with their bubble … Continue reading Bubble Nets & Torodial Air-Core Vortex Rings
When people think of a bivalve organism, they should typically imagine a sessile animal with it’s shell partially or fully buried in the sand and feeding through its elongated siphon which filters out plankton in the water column. A scallop, the only migratory bivalve organism, seems to defy many stereotypical morphological features that are endemic to the class Bivalvia. Obviously since they are not sessile, they have had no need to develop a way to anchor themselves in one spot. Infaunal bivalves such as clams, have developed a foot that elongates and helps them bury themselves in soft substratum. Similarly, … Continue reading Migratory Bivalve?? No way man.
